The basic intent of watershed management is similar to ecosystem-based management. An ecosystem approach accounts for the interrelationships among land, water, air, and living things, including humans, and involves all user groups in comprehensive management. An ecosystem approach can be symbolized as a circle with three equal compartments representing social, economic, and environmental interests (Figure 1). The operating principle of an ecosystem approach is that no segment of the circle can be sacrificed and all are essential to maintain a functional and sustainable ecosystem. In addition, an ecosystem approach to watershed management works to ensure win-win solutions among economic, environmental, and societal interests.
Figure 1. An ecosystem approach to watershed management.
What watershed planning and management and ecosystem-based management are trying to accomplish is to comprehensively address contaminant (e.g., point and nonpoint sources, contaminated sediment remediation), physical (e.g., flow augmentation, streambank stabilization, physical habitat modification), and biological (e.g., stocking/harvesting, wetland restoration and enhancement, food web manipulation) management alternatives that will achieve locally-based, ecosystem goals. Such site-specific, ecosystem goals are established based on ecosystem characteristics, public needs, and scientific, regulatory, and resource management input.
Historically, many people have believed that when environmental concerns win, economic concerns lose, and vice-versa. That doesn't have to be the case. Watershed and ecosystem-based management provide a balance among environmental, economic, and societal issues, forming win-win situations.
On May 3, 1996 a Practical and Cost-Effective Watershed Management Conference was held in Livonia, Michigan. The conference attempted to move beyond theory to practice by presenting practical and cost-effective methods for implementing watershed management. The conference included technical sessions on:
Over 300 people participated, including township, village, and city elected officials; planning and zoning officials; government managers and staff; developers; builders; consultants; planners; engineers; landscape architects; park and subdivision design and review consultants; road commissioners and staff; drain commissioners and staff; citizen groups; property owners; and other stakeholders. The purpose of this summary report is to:
Watershed management is not a new concept, however, its practical application is. Watershed management attempts to apply an ecosystem approach. An ecosystem approach is both a way of doing things and a way of thinking. Themes inherent in an ecosystem approach:
Adopting an ecosystem approach to watershed management means undertaking holistic planning, research, and management. In governmental regulatory and resource management agencies, adopting an ecosystem approach has initiated a shift from a narrow perspective of managing a single environmental medium (e.g., water, air) or a single resource (e.g., fish, trees) to a broader perspective that focuses on managing human uses and abuses of watersheds or bioregions, and that addresses all environmental media and resources in a comprehensive and systematic fashion. For example, Fisheries Division of Michigan Department of Natural Resources, Land and Water Management Division and Surface Water Quality Division of Michigan Department of Environmental Quality, and Michigan's Office of the Great Lakes have all adopted a common approach to watershed management and agreed to cooperative action.

Watershed Management is a process of decision-making regarding uses and modifications of lands and waters within a watershed. This process provides a chance for communities to balance diverse goals and uses for local resources, and to consider how their cumulative actions may affect long-term sustainability of these resources. Human modifications of lands and waters directly alter delivery of water, sediments, and nutrients, and thus fundamentally alter aquatic systems. People have varying goals and values relative to uses of local land and water resources. Watershed management provides a framework for integrated decision-making, where we strive to: 1) assess the nature and status of the watershed ecosystem; 2) define short-term and long-term goals for the system; 3) determine objectives and actions needed to achieve selected goals; 4) assess both benefits and costs of each action; 5) implement desired actions; 6) evaluate the effects, actions and progress toward goals; and 7) re-evaluate goals and objectives as part of an iterative process. As a form of ecosystem management, watershed management encompasses the entire watershed system, from uplands and headwaters to floodplain, wetlands and river channels. It focuses on the processing of energy and materials (water, sediments, nutrients, and toxics) downslope through this system. Of principle concern is management of the basin's water budget, that is the routing of precipitation through the pathways of evaporation, infiltration, and overland flow. This routing of groundwater and overland flow defines the delivery patterns to particular streams, lakes, and wetlands; and largely shapes the nature of these aquatic systems. Watershed management requires use of the social, ecological, and economic sciences. Common goals for land and water resources must be developed among people of diverse social backgrounds and values. An understanding of the structure and function - historical and current - of the watershed system is required, so that the ecological effects of various alternative actions can be considered. The decision process also must weigh the economic benefits and costs of alternative actions, and blend current market dynamics with considerations of long-term sustainability of the ecosystem. |
At the federal level, considerable emphasis is also being placed on management of places, instead of simply managing programs. U.S. Environmental Protection Agency refers to this as "place-based environmental management" (i.e., the work of agencies and organizations should be driven by ecological, economic, and social needs of communities and ecosystems). Critical success factors for place-based environmental management include:
Such national emphasis will undoubtedly provide greater impetus to implement an ecosystem approach within local watersheds and bioregions.
Education and cooperative learning are fundamental to the success of cooperative, watershed management. No one has all the answers. Everyone is on the learning curve. The process of cooperative learning must ensure respect for different perspectives, while striving for agreement on common goals and actions. Like "place-based environmental management", watershed-based educational processes must be founded on a sense of place that is linked to concepts of an ecosystem approach and bioregionalism.
Within the process of implementing an ecosystem approach to watershed management there is a need to initiate short-term actions while undertaking long-term planning. This is referred to as adaptive management where priorities are set, actions are implemented, and monitoring of effectiveness is performed in an iterative fashion for continuous improvement. Emphasis should be placed on a step-wise approach to implementation, with demonstration of incremental progress in order to sustain momentum required to realize the vision and goals of watershed management.
Session participants recognized that one of the major challenges in ensuring that habitat is adequately addressed in watershed management efforts is that "habitat has no home" (i.e., physical habitat often "falls through the cracks" and does not receive adequate attention in traditionally separate water quality management and fish and wildlife management programs). To address this challenge there must be a concerted effort to ensure that habitat is an integral part of community master plans. Critical components of a process to ensure that habitat is incorporated into community master plans include:
Options to be considered in plan development include:
Higher priority must be given to soft engineering alternatives to achieve "win-win" outcomes for habitat and economic development, so as not to preclude future options.
There is no doubt that higher priority must be given to adequate monitoring and assessment, including inventories and classifications systems. Session participants suggested that individuals must get involved up-front in project planning to adequately address habitat and ensure adequate assessment and monitoring. In addition, habitat rehabilitation and enhancement projects should be viewed as experiments, so as to help ensure follow-up assessment in order to guide future habitat projects.
From a strategic perspective, greater emphasis needs to be placed on "piggy backing" habitat protection and rehabilitation on other local and regional planning and development initiatives. For example, communities can capitalize on the opportunity of waterfront redevelopment to ensure that habitat gets incorporated into master plans. Effective communication and strong partnerships will be essential to achieve this. Although a systematic and comprehensive process of habitat conservation, rehabilitation, and restoration will be a long-term endeavor, considerable opportunities exist to move forward with short-term actions which will benefit habitat and other issues (e.g., land use, economy, agriculture, recreation). Some examples of practical actions include:
Additional practical actions need to be identified. As well, the values and benefits of these practical actions need to be quantified and communicated to all stakeholders to ensure continued progress toward healthy and sustainable watersheds and ecosystems.

Melding Wetlands, Wildlife, and Water Quality With Stormwater Design
Introduction
As natural resource consultants, Resource Management Group, Inc. (RMG) is often charged
with the responsibility of assisting a client in meeting environmental or local zoning regulations.
With the responsibility comes the opportunity of creating innovative solutions to environmental
problems which result in a win-win situation for the environment and the proposed project.
Usually, economics drive the willingness of a client to propose or consent to innovative resource
protection or enhancement measures; however, more and more people are realizing good
watershed stewardship is good economics and new approaches to old problems are becoming more
common. This presentation is an extremely brief discussion of the problems being faced, the
opportunities before us, and the results we may be able to attain by melding of wildlife, wetlands,
and water quality with stormwater design.
Objectives
With many developments, engineering and site planning, in compliance with zoning
regulations, dictate the design of the project. The primary objectives of stormwater control
infrastructure are to control the amount of runoff leaving a site and attempt to improve the
quality of stormwater entering lakes, streams, or rivers. Habitat considerations are usually last on
the list, well below the aforementioned, dwelling density, and others. Lack of awareness is
probably the reason for wildlife habitat loss. The objective of this conference and our work at
RMG is to inform people how to create more win-win for wildlife.
Discussion
For many years, stormwater control equated to large rectangular pits, surrounded by a chain
link fence, which were constructed and forgotten. Present day, evolving best management
practices for stormwater management involves a "treatment train" approach with basins which are
blended with the landscape and mitigate wildlife habitat impacts. Stormwater treatment with the
system approach often includes natural or created wetlands as a key component of the design.
Wildlife concerns should be more of a consideration in development and professional
biologists need to be involved in those decisions. In all cases, development is disrupting to wildlife
to some degree. The old line of "the birds and bunnies will move across the road" is not
ecologically correct; loss of habitat equates to loss of wildlife. The degree of impact depends on
the quality of the habitat; maintaining a diversity of vegetation provides better wildlife habitat.
Many wildlife species are mobile, having daily, seasonal, or annual migrations. Some are less
mobile and have a smaller "home range" where they spend their entire lives. The less mobile
species will suffer most by destruction or alteration of their habitat. Analysis of wildlife habitat
should exceed the boundaries of the project area and be evaluated on a landscape (watershed)
basis. Wildlife travel corridors between areas of quality habitat can be as important to wildlife as
the habitat itself. Roads, especially roads carrying large volumes of high speed traffic, are not
good wildlife habitat. Bisecting high quality wildlife habitat components with roads can impair
wildlife populations in perpetuity, due to constant mortality by vehicles as animals attempt to
move between habitat units to feed, rest, or raise young.
A professional biologist should determine the wildlife species inhabiting a project site and
determine the ecological relationships between the habitat on the site and the animals living
there. With this basic understanding, biologists must be an integral part of the development
team and be given appropriate consideration for input to the site design. Mitigating measures
should be employed to avoid impact on valuable habitat wherever practical, minimize impacts
which cannot be avoided, and compensate for unavoidable impacts to wildlife.
Most frequently, wildlife habitat protection is not a requirement, except for upland open space
requirements, regulated woodlands and wetlands. The "open field" habitat type is most often
sacrificed because it is not regulated, per se', unless it is saved as upland open space (i.e. non-
wetland or woodland). Even then, wildlife ecology is not considered; only where it is not possible
to place lots or parcels is natural open field habitat preserved, but not as a result of a valuable
wildlife use. Wetlands, which often have a diverse and important wildlife component, are
generally well-protected by local, state, and federal regulations. The same is true with riparian
habitat, streams, rivers, and lakes.
The following three E's should be considered when planning the stormwater treatment
system for a proposed development. Engineering requirements must be followed to ensure the
proper functioning of the system and to comply with local regulations. Ecology should be a
strong consideration, allowing the project design team to blend the stormwater system with the
natural environment which existed prior to development. Economics, not from the perspective of
reducing costs of stormwater design and construction, but from the proven adage that good land
stewardship is good economics. In the long term it pays to follow the three E's, because the
quality and long term effectiveness of the stormwater treatment system will help to make the
development more attractive.
The following practices are part of the blueprint to accomplish the three E's:
Conclusion
Given the obvious benefits to the environment and good economic sense of innovative
stormwater management, it is incumbent upon landowners to take the responsibility for good
stewardship of wildlife resources in the use of their land and it is incumbent upon natural
resource professionals and governmental units to educate people about the watershed approach to
planning and land use. Only through education and commitment will proper due be given to all
aspects of our natural systems.
Evolution of Streambank Stabilization and Watershed Restoration in N. Michigan
The Huron-Manistee National Forests are located in northern Michigan within a day's drive
of one quarter of the nation's population. Its most prized features include the northwoods rivers
and streams. People use these rivers for fishing, canoeing, or just to find solitude from an urban
setting. They also provide habitat for many aquatic and riparian-dependent species, some which
are threatened or endangered. Unfortunately, many of these streams carry excessive sand,
degrading aquatic habitat. Thus, a great deal of energy and resources applied to northern
Michigan rivers is oriented towards erosion control to reduce sediment delivery.
Traditionally, much of the river restoration work undertaken in northern Michigan has
focused on streambank erosion. It was demonstrated from research on the Pine River, a typical
northern Michigan stream, that slightly more than half of the sand bedload was directly
attributable to eroding streambanks. Initially, stabilization was done on a site-by-site basis, with
site selection often being dictated by the squeaky wheel philosophy. However, in the 1980s a
more systematic approach was adopted and eroding streambank inventories were done for entire
river systems. This yielded a "big picture" perspective. This systematic approach also drew
attention to the challenge of mixed private, state, and federal land ownership patterns within
many northern Michigan forested watersheds. While ownership may be mixed, it was recognized
that rivers within these watersheds have a total disregard of both property and political
boundaries. Water resource problems anywhere along a watercourse will have an impact on
downstream riparian values; therefore ownership of these problems had to be taken on by all
riparian landowners.
The systematic streambank erosion inventories also pointed out the high costs associated
with the big picture approach. For instance, it was estimated that it would take $1.5 million to
stabilize the 100 severe and moderately eroding streambanks in 40 miles of the Pere Marquette
River system. Obviously, no one agency or organization had the financial resources to take on
such a project. Thus, a partnership between state, federal, and private organizations was
developed to address such a large-scale river restoration project. Six partners (Michigan
Department of Natural Resources, Pere Marquette Watershed Council, Trout Unlimited,
Mason-Lake Soil Conservation District, Northwest Michigan Resource Conservation and
Development Council, and the U.S. Forest Service) have collaborated to stabilize these eroding
streambanks over the past 10 years.
Concurrent with the evolution of streambank stabilization from the site scale to the
landscape scale, the techniques employed have also changed over the years. Historically, wooden
structures were often used to stabilize eroding streambanks. However, while many of these
structures were initially successful in stabilizing eroding streambanks, most became defunct due
to lack of maintenance and subsequently were damaged or lost during high flow events.
Recognizing this problem, the majority of eroding streambanks are now stabilized using
fieldstone riprap. Wisconsin "LUNKER" structures are also being incorporated. These
structures enhance the traditional riprap stabilization by simulating a natural undercut bank. In
areas where equipment access is limited, techniques such as whole-tree revetments are used . All
techniques are being done through a bio-engineering approach, that being combining vegetation
with the structural technique. This vegetation adds a "living" aspect to the stabilization which
increases the structural integrity of it. It also helps maintain the outstanding scenic character of
our northwoods rivers, many of which are designated National Wild and Scenic Rivers or State
Natural Rivers.
Our outlook towards streambank stabilization is also changing from a species orientation to
more of an aquatic ecosystems perspective. Initially stabilization focused entirely on improving
spawning and rearing habitat for trout and salmon. However, taking an ecosystems viewpoint
meant considering the needs of all riparian-dependent species. For instance, it was discovered
that the wood turtle, a State "species of special concern", uses southerly exposed eroding
streambanks for its nesting habitat. The needs of wood turtles are now integrated into
streambank stabilization programs as important nesting sites are identified and protected.
Management of large woody debris, especially as it relates to recreational watercraft, has also
become part of erosion control programs. Woody debris can protect fragile streambanks,
especially during flood events. In a sense, it functions similar to a baffle system, dissipating
stream energy during higher flows. Remove it and the erosive power of stream flows is increased
and streambank erosion can be greatly accelerated. The U.S. Forest Service, in cooperation with
the Michigan DNR and river user groups, has developed guidelines for woody debris removal on
National Forest streams which balance safety concerns for boaters with aquatic ecosystem
protection. At the same time, we have a goal of long-term woody debris recruitment from our
riparian forests.
While streambank stabilization has evolved from the site scale to the landscape scale as part
of river restoration programs, resource managers have also realized that we needed to broaden
our vision beyond the stream, looking at the entire watershed. Another key piece of the sediment
delivery puzzle in northern Michigan watersheds are road-stream crossings, especially when viewed
from a cumulative perspective across the landscape. Similar to the large-scale streambank erosion
inventories conducted in the 1980s, watershed-wide inventories of road-stream crossings began in
the early 1990s. Each crossing has been assigned a severity ranking along with recommended
actions for reducing sediment delivery. These inventories, when combined with the
comprehensive streambank erosion inventories, have allowed managers to use a landscape
approach in determining priorities in watershed restoration efforts.
Habitat Development on Industrial and Private Property: The St. Clair River
Waterways for Wildlife Program
Corporations own about 25% of the privately owned land within the United States.
National programmatic efforts to preserve and protect our natural resources for future
generations should and need to include the corporate sector. The Wildlife Habitat Council
(WHC) with its corporate and conservation members, is demonstrating that corporations can and
are willing to act in a voluntary manner to protect the environment. WHC is a non-profit, non-
lobbying organization established in 1983 as a joint venture between the corporate and
conservation communities. The Council encourages and aids corporations in the development
and establishment of voluntary wildlife management programs on corporate lands. WHC
members currently manage nearly 300,000 acres of property for wildlife at over 350 sites
internationally.
Through the Waterways for Wildlife program, WHC is working with Detroit Edison, Ontario
Hydro, Terra International, Consumers Power, Ford Motor Company and other corporate and
conservation groups to establish and implement an international watershed management plan for
the St. Clair River which flows between Michigan and Ontario. The Waterways for Wildlife
Project is a WHC program that is designed to promote voluntary cooperative habitat
enhancement efforts on a regional scale. The programs are driven by both the private and public
sectors and involve multiple landowners. Waterways for Wildlife projects are built around wildlife
enhancement efforts initiated by WHC member corporations along river corridors. These
successful efforts are used as models to encourage participation from neighboring public and
private managers.
The St. Clair River Waterways for Wildlife program will focus on engaging corporate and
private landholders in management of their properties to achieve project objectives as identified by
the general program participants in a plan scheduled for release during the summer of 1996.
Although just beginning, the St. Clair River Waterways for Wildlife program has achieved some
notable early results including engaging conservation, corporate, and natural resource agencies in
joint discussions regarding habitat enhancement activities in the watershed, coordinating a joint
reforestation effort on the Darcy McKeough Floodway Channel between the St. Clair Region
Conservation Authority and Detroit Edison, establishing an international Steering Committee of
conservation organizations and corporations to spearhead the project, partnering with the Rural
Lambton Stewardship Network and the Ontario Ministry of Natural Resources on several
restoration and management projects, and aiding Detroit Edison in the expansion of their wildlife
management program at the Belle River Power Plant and other properties in the St. Clair River
Basin. Through the Waterways for Wildlife program for the St. Clair River, project participants
are protecting and enhancing habitat along the river, using scarce financial resources more
efficiently, contributing to the long-term health and viability of the river and protecting habitat
for riparian, upland, and prairie-associated wildlife.
Design Of Structures, Trails And Bike Paths
The design of environmentally sensitive improvements for recreational uses goes far beyond
decisions regarding practical and cost effective construction techniques and materials. While
these questions are important in the overall process, first and foremost one must be totally
familiar with the site and the characteristics that make it unique. Secondly, one should have a
good understanding of the type, frequency and intensity of both the existing and the anticipated
uses. Maintenance and budget are obvious concerns, also. Not until all of this information has
been gathered can appropriate solutions to specific design issues such as the what, the where and
the how be more easily derived.

Reshaping Shorelines for Habitat in Lake Superior's North Shore Areas of Concern
Introduction
Along the north shore of Lake Superior, the International Joint Commission has designated
four sites for development of Remedial Action Plans (RAPs) to restore and protect water quality.
During the early stages of RAP development, it was clear that the loss of fish and wildlife habitat,
one of fourteen use impairments outlined in the 1987 Great Lakes Water Quality Agreement,
had occurred in each of Thunder Bay, Nipigon Bay, Jackfish Bay and Peninsula Harbour Areas
of Concern (AOCs). Community input in each of the AOCs involved the development of
specific "Water Use Goals," and emphasized the need to address incidental habitat in the context
of social, economic as well as ecological issues. As a result, a number of habitat projects were
developed to restore specific degraded habitat and demonstrate new techniques that could be
applied to other areas in the Great Lakes basin.
In the summer of 1990, habitat projects submitted for the North Shore AOCs were approved
under the federal Great Lakes Cleanup Fund (CUF). The newly formed Lake Superior
Programs Office (LSPO), a cooperative initiative with Environment Canada, the Department of
Fisheries and Oceans and the Ontario Ministries of Natural Resources and Environment and
Energy, was responsible for the coordination and administration of the Lake Superior RAPs and
CUF habitat projects. Initial financial support of $4.4 million from the Great Lakes Cleanup
Fund has generated an additional $10.3 million over a five year period from more than 34
project partners representing federal and provincial agencies, municipalities, industry, community
organizations and the public.
Program goals for habitat projects include improving ecosystem health in the AOCs and
encouraging public involvement and understanding of environmental concerns in the Lake
Superior basin. Individual projects aim to demonstrate our ability in restoring degraded habitat,
increasing habitat diversity, developing experimental techniques to restore fish populations and
in-situ treatment of contaminated sediments. Extensive monitoring of projects allows
documentation of successes and transfer of knowledge and technology to other AOCs. Since
1990, the LSPO has evolved from the development of concepts to the implementation and
completion of many projects.
A number of habitat projects in Thunder Bay and Nipigon Bay deal exclusively, or in part,
with degraded or lost nearshore aquatic habitat. Remedial actions, identified through extensive
public consultation in each community, have focused on specific themes including breakwall
construction, island construction, shoreline reshaping and wetland creation and restoration.
Three completed examples of incorporating habitat enhancements into shoreline development are
presented.
Sanctuary Island
Degradation of aquatic habitat in tributaries entering Thunder Bay harbour was identified by
the RAP Team and the RAP Public Advisory Committee as a major impairment in the AOC.
Work at the mouth of McVicar Creek has restored spawning habitat for native fish, restored
physical attributes of the Creek and will prevent future bank erosion. Sanctuary Island, a 205
metre crescent-shaped island, was constructed adjacent to the mouth of McVicar Creek. This
island/wetland complex has created diverse new fish and wildlife habitat and new recreational
opportunities for the public along this section of the Thunder Bay waterfront. Habitat
enhancements such as in water rock shoals and sediment traps, and planting pods on the island
itself have been successful in increasing the aquatic and terrestrial habitat diversity of this
structure. In addition, submergent aquatic vegetation has colonized the leeward side of the
Sanctuary Island between the Island and mainland.
McKellar Ponds
On the McKellar River in Thunder Bay, dredging for commercial shipping has transformed
this once productive arm of the Kaministiquia River delta into a straight, steep banked channel.
Two 1.5 ha lagoons have been excavated at the river mouth to create a unique area of shallow,
productive habitat for fish spawning, waterfowl nesting, fish and wildlife viewing and educational
opportunities. Post construction assessment has verified use of the ponds by a number of fish
species, benthic organisms, wildlife and waterfowl.
Red Rock Marina
In Nipigon Bay, the Township of Red Rock initiated construction of a marina/park in the
summer of 1991. The Nipigon Bay RAP Team and RAP Public Advisory Committee have
worked closely with the Waterfront Development Steering Committee to incorporate
environmental components into the breakwater design. Construction has been completed to
overlay a standard armour stone breakwall with suitable habitat enhancements designed to
increase diversity in the nearshore aquatic ecosystem, improve public access and provide improved
aesthetics and additional recreational opportunities to marina/park users. The completed
breakwater is the first of its kind in Ontario, and will provide an excellent model for future
waterfront developments in the Great Lakes basin. This demonstration project will be directly
applicable to not only marina developments, but a wide variety of structures that are designed to
harden shorelines for the purpose of erosion control and/or storm protection.
Conclusion
Successful implementation of the Lake Superior Cleanup Fund Program can be attributed to
committed partnerships at all levels of program delivery. The Lake Superior Programs Office has
provided a demonstration where federal and provincial agencies, in times of severe financial
constraint, can effectively share resources and expertise to reduce program costs, minimize
overlapping mandates and develop real partnerships with industry and the public. The combined
efforts of the agencies, industry and the public have resulted in the restoration of habitat in
Nipigon Bay and Thunder Bay.
Controlling Sediment Delivery At Road/Stream Crossings in Northwest Michigan
In 1985, the Northwest Michigan Streambank Erosion Inventory found moderately and
severely eroding streambanks and road/stream crossings to be the two primary sources of sediment
pollution to the majority of the rivers in northwest Michigan. Recent road/stream inventories
have determined that severely eroding crossings can deliver up to 500 tons of sediment per year
while moderately eroding sites deliver up to 100 tons per year. The cumulative effect of
sedimentation from these crossings is tremendous. Excessive and bedload destroys fish and
wildlife habitat by filling deep pools, decreasing hydrologic diversity and covering spawning gravel
and aquatic substrate. The sediment also degrades water quality by carrying oils, greases and
other pollutants into the water.
The Northwest Michigan Resource Conservation and Development Council has pioneered
the road/stream inventory, ranking, costing, mapping and database methods on the Pere
Marquette, Pine and Little Manistee watersheds. With inventories in hand, the RC&D Council
has been successful in bringing together non-traditional partners and funding sources to address
problem crossings on a prioritized, worst-first basis. During 1993 to 1995, the RC&D Council
has received four different watershed wide grants totalling more than $400,000 from the
Michigan Department of Transportation ISTEA program to help improve many of the most
severe crossings on the Pine and Pere Marquette watersheds. Road commissions, private interest
groups and water quality agencies cooperate on the projects. This funding would not have come
without the inventories.
Best Management Practices (BMPs) are selected to best control erosion and sediment
delivery for each unique stream crossing condition and are recognized as the most effective
treatments for controlling sedimentation. Recommended BMPs include: drainage control
structures such as culvert replacement or extension, diversions and sediment basins. Each
measure will eliminate or significantly reduce sedimentation immediately after installation, and
will continue to control this primary nonpoint source in the future.
A road/stream inventory also provides for continued implementation of BMPs as
participants are educated through the inventory process. Road commissions begin to evaluate all
crossings from both a transportation and water quality aspect. They then incorporate water
quality improvements into routine improvements or enhancements, and work with neighboring
road commissions teaching them how to improve crossings in adjacent watersheds.
Managing Open Spaces for Biological Diversity
Introduction
The citizens of Ann Arbor, Michigan (pop. 111,000) are proud of their parks. They have
repeatedly shown their support by voting to tax themselves to generate additional revenue to
improve the park system. A 5-year "Parkland Acquisition Millage" was approved in 1988 to add
additional acreage to the park system, much of it to be preserved in a natural, undeveloped state.
As a result of this millage, the current city park system stands at 133 parks, containing
approximately 2,000 acres, one-half of which are undeveloped. In 1993, as the "Parkland
Acquisition Millage" was drawing to a close, the voters overwhelmingly supported a new .37 mil
"Park Maintenance and Repair Millage." This 5-year millage generates nearly $1 million per
year, with more than 15% of it earmarked specifically for "Natural Area Preservation and
Management."
A portion of these funds was used to create a new permanent position with the Department
of Parks and Recreation entitled, "Natural Area Preservation Coordinator." The primary mission
of this position is to "preserve, protect, and care for the natural areas of Ann Arbor, especially
those in the City's park and recreation system." Additionally, the Natural Area Preservation
(NAP) Coordinator serves as an in-house environmental consultant to the other divisions within
the Parks Department (Recreation, Operations/Maintenance, Forestry/Horticulture, Planning,
and Administration), as well as other departments within the city. But the main work of the
NAP Division falls into two categories: Ecological Assessment, and Ecological Restoration and
Stewardship.
First Step - Ecological Assessment
Aldo Leopold once said, "The first step of intelligent tinkering is to save all the parts."
Before we start tinkering with our natural ecosystems and trying to do "restoration," we need to
make sure we save all the parts. That means we need to inventory what the various parts of the
ecosystem are, and also try to assess the status of these natural areas. This was done in a general
way by several city-wide assessments of natural features. Some attempt was also made to identify
and map the various natural communities within the city. Although this effort gave a general
impression of where the natural areas were within the city, it did not provide any answers to some
of the key questions such as: Which area has the highest priority for management? How should
it be managed? What are the ecological threats to this natural area? Within a given park, where
is the best place to locate a trail to minimize environmental impact?
To answer these specific questions, NAP launched a city-wide inventory of the plants,
butterflies, frogs, and breeding birds within the parks and other natural areas. In the first
summer, 1994, 75 volunteers adopted parks in which they attempted to inventory every tree,
shrub, and wildflower species present. They were trained by three staff botanists who offered six
hours of free on-site plant identification training every week. By the end of the summer,
volunteers had spent 300 hours sharpening their plant taxonomy skills. The training paid off; in
the 50 natural areas inventoried in the past two summers, 926 species of plants have been
recorded, 17 of which are listed as "endangered," "threatened," or "special concern" in the State of
Michigan. The other inventories have yielded equally informative (and impressive) data after only
one year: 52 butterflies species (1 of special concern), 8 of southern Michigan's 11 frog and toad
species, and 87 breeding bird species.
Interpreting the Assessment - Setting Priorities
So what can an inventory of the plant and animal life of each natural area tell you? It can
begin to provide answers to many questions. Is this site populated with native or alien species?
What were the original plant and animal communities on this site? How easily can these
communities be restored? How has this site changed over time? How will various management
practices effect this site? Are there any legally-protected, threatened or endangered species here?
Which natural areas are most threatened by invasive species? What type of recreational activities
are appropriate in this natural area?
Although these inventories will be repeated and refined in coming years, they have already
provided valuable information for us to use when making management decisions. Once the
location of a rare species is identified and mapped, we can steer development away from that site.
By knowing more about the local populations of butterflies, we can make wiser decisions about
the best response to the infestation of Gypsy moths which have just reached Ann Arbor. Data on
frog populations will help us monitor the ecological health of wetlands in the city, especially those
affected by stormwater development from new subdivisions. As more and more information
about a site's natural features is compiled, the overall ecological significance of the site, and the
restoration potential of the site, begin to emerge.
So far, the main focus of the inventory efforts has been in the city's park system to help us
better manage those sites. In the future, what is most needed is a similar area-wide effort in all
the undeveloped properties. If a region-wide inventory of natural features can be done without
regard to property boundaries, then decisions on zoning and development patterns can be made
much more wisely, and without the narrow-focused debates brought on by proposals to develop
individual plots of land.
Until such a comprehensive planning effort is accomplished, we must rely on other stop-gap
measures. For 15 years, the city has been struggling to develop a fair but effective "Natural
Features Ordinance." NAP staff are involved in these efforts and have helped to strengthen the
wording of the ordinance, such as by providing more protection for large, landmark trees on a
site. In the city's new "Wetland Preservation Ordinance," NAP staff used their expertise on the
most troublesome invasive plant species of southeast Michigan to help develop the "Invasive
Species List" for the ordinance. This lists over 100 species of invasive plants which may not be
planted in a wetland mitigation. We have also developed a Native Landscaping brochure to help
developers and homeowners find alternatives to commonly-used, exotic, horticultural species.
Ecological Restoration and Stewardship
Perhaps worrying about what species are being planted in the city seems like a trivial matter.
But within Ann Arbor's natural areas, invasive species have emerged as the #1 ecological threat.
Whether it's Gypsy moths, Zebra mussels, purple loosestrife, buckthorn, honeysuckle, or
something else, non-natives are overrunning the natural systems.
What do we mean by natural? As our definition of natural, we look at the ecological systems
in southeastern Michigan as they were immediately prior to European settlement in the late
1700s and early 1800s. Luckily, those environmental conditions are not as mysterious to us as
they may first appear. In the early 1800s, surveyors from the federal General Land Office laid
out the townships with their 36 square-mile sections that create the checkerboard appearance so
evident to an airline passenger flying over the Midwest. The survey for the Ann Arbor area was
done in 1819, five years before the city was even founded. To the careful reader, the survey notes
- available in county courthouses in most Midwest counties - give details about the type and size
of ecosystems present in each square mile of land. They even reveal which tree and shrub species
inhabit the area.
Although 1819 was a long time ago for us, it was just yesterday to the plant and animal
species which have lived in this environment for millennia. Although the landscape has changed
drastically in the 177 years since then, the climatic and environmental factors to which those
native organisms are adapted have not changed appreciably. The plants best adapted to live in
southeast Michigan then are still the same ones best adapted to live here now - and the ones most
important to the native butterflies and other animals that use them as food.
What does all of this mean to the management of natural areas? A major activity of NAP
staff is to physically remove invasive plant species in an attempt to restore the native flora of the
Ann Arbor area. We cut and remove shrubs, and herbicide their stumps. We re-introduce fire as
a natural process in fire-dependent communities. Just this spring alone, we have conducted 17
prescribed ecological burns in city parks to help restore the native prairie and oak savanna
ecosystem once present in the Ann Arbor region. We also collect native seeds and sow them in
landscapes we are trying to restore.
Education
In addition to physically altering the landscape and restoring native ecosystems, education of
the public is vital. All the millages and grants in the world cannot protect the natural areas of
Ann Arbor or anywhere else if the environmentally-damaging attitudes and behaviors of people
don't change. It does no good to remove honeysuckle from a park if the neighbors keep planting
it in their backyards. It does no good to set aside a natural area if there is no will to care for it, or
even an appreciation of why it is special.
In an attempt to reach out to the public and involve them in local stewardship issues, and to
multiply the efforts of a limited number of staff, we have launched a major Volunteer
Stewardship Campaign. At least twice a month, NAP staff hold volunteer work days in one of
the 50 or so natural areas in the city park system. The work usually involves cutting and hauling
invasive shrubs, but the impact - we hope - goes much further. After spending three hours on a
Saturday morning hauling brush and learning some natural history, citizens develop a kinship
with their neighborhood park. They keep an eye on it when staff are not present. And they think
twice before planting that honeysuckle in their backyard.
Land Protection and Conservation Methods
The Southeast Michigan Land Conservancy (SMLC) is a non-profit charitable corporation
serving the seven county southeast Michigan region. The mission is to preserve parks, open space
and natural areas for environmental protection and wildlife habitat, and to enhance the quality of
life for area residents.
SMLC protects land by purchasing it, by accepting donations of land, and by holding
conservation easements on land to protect critical natural features. Since incorporating in 1988,
SMLC has protected 655 acres through 15 projects with a land value of $3 million. Of these
projects, three have been land purchases, seven have been land donations, and five have involved
conservation easements.
In general, there are four principle conservation methods available to protect land (i.e., land
acquisition, purchase of development rights, planning and zoning, and conservation easements).
Land Acquisition
The Michigan Natural Resources Trust Fund (MNRTF) is the principle funding source for
land acquisition in the state. It is a constitutionally-protected fund which derives its revenue
from royalties on the extraction of oil, gas, and minerals from state lands. There is a 25% local
match requirement, although this may be supplied by the landowner. The MNRTF can also fund
less than fee simple ownership (purchase of development rights). Local governments must have
an adopted Recreation Master Plan on file with the Michigan Department of Natural Resources
to be eligible for grants. Citizens may also nominate lands for acquisition. The application
deadline is April 1st. For grant materials and further information contact:
Purchase of Development Rights (PDR)
The Michigan Department of Natural Resources administers a fund under PA 116, the
Farmland and Open Space Preservation Act, to purchase development rights on critical
farmland. Applications have to be submitted by April 1st. Grant information is available from:
Local communities can also enact programs to purchase development rights. At present,
Peninsula Township near Traverse City is the only Michigan community with an adopted PDR
program. Other communities, however, are investigating this effective planning tool.
Planning and Zoning
Local governments retain significant authority to shape their local landscape. Properly
enacted zoning can be used to protect agriculture, rural residential and conservation features.
Zoning can be bolstered by cost-effective Purchase of Development Rights programs. Numerous
studies have documented that most new development is a net tax drain on a community, leading
to higher taxes to pay for the increased demands for infrastructure, schools, police and fire, etc.
Conservation Easements
A conservation easement is a legal agreement a property owner makes to restrict the type and
amount of development that may take place on his or her property. Each easement has
restrictions which are tailored to the particular property and to the interests of the individual
owner.
To understand the easement concept, think of owning land as holding a bundle of rights. A
landowner may sell or give away the whole bundle, or just one or two of those rights. These may
include, for example, the right to construct buildings, to subdivide the land, to restrict access, or
to harvest timber. To give away certain rights while retaining others, a property owner grants an
easement to an appropriate third party.
The specific rights a property owner forgoes when granting a conservation easement are
spelled out in each easement document. The owner and the prospective easement holder identify
the rights and restrictions on use that are necessary to protect the property - what can and cannot
be done with it. The owner then conveys the right to enforce those restrictions to a qualified
conservation recipient, such as a land trust organization or public agency.
Why Grant a Conservation Easement?
People grant conservation easements to protect their land or historic buildings from in
appropriate development while retaining private ownership. By granting an easement in
perpetuity, the owner may be assured that the resource values of his or her property will be
protected indefinitely, no matter who the future owners are. Granting an easement can also yield
tax savings, as discussed below.
What Kind of Property Can be Protected by an Easement?
Any property with significant conservation or historic preservation values can be protected by
an easement. This includes forests, wetlands, farms, endangered species habitat, beaches, scenic
areas, historic areas, and more. Land conservation and historic preservation professionals can
help you evaluate the relative features of your property.
Who Can Grant an Easement? To Whom Can They Grant It?
Any owner of property with conservation or historic resources may grant an easement. If the
property belongs to more than one person, all owners must consent to granting an easement. If
the property is mortgaged, the owner must obtain an agreement from the lender to subordinate
its interests to those of the easement holder so that the easement cannot be extinguished in the
event of foreclosure.
If an easement donor wishes to claim tax benefits for the gift, he or she must donate it or sell
it for less than fair market value to a public agency or to a conservation or historic preservation
organization that qualifies as a public charity under Internal Revenue Code Section 501 (c) 3.
The Southeast Michigan Land Conservancy, as well as most land trust organizations, meet this
criterion.
Holding an easement, however, is a great responsibility. A property owner should make sure
that the recipient organization has the time and resources to carry out that responsibility. An
organization that accepts the donation of an easement typically will ask the owner to make a
contribution toward the costs of monitoring and defending the easement in perpetuity or will
establish a monitoring fund from other sources.
How Restrictive is an Easement?
An easement restricts development to the degree that is necessary to protect the significant
values of that particular property. Sometimes this totally prohibits construction, sometimes it
doesn't.
If the goal is to preserve a pristine natural area, for example, an easement may prohibit all
construction, as well as activities that would alter the natural character of the land. If the goal is
to protect farm land, however, an easement may restrict subdivision and development while
allowing for structures and activities necessary for and compatible with the agricultural operation.
Even the most restrictive easements typically permit landowners to continue traditional uses of
the land.
How Long Does an Easement Last?
An easement can be written so that it lasts forever. This is known as a perpetual easement.
Where state law allows, an easement may be written for a specified period of years, and this is
known as a term easement. Only gifts of perpetual easements, however, can qualify a donor for
income and estate tax benefits. Most recipient conservation and historic preservation
organizations accept only perpetual easements.
An easement runs with the land - that is, the original owner and all subsequent owners are
bound by the restrictions of the easement. The easement is recorded at the county records office
so that all future owners and lenders will learn about the restrictions when they obtain title
reports.
What are the Grantee's Responsibilities?
The grantee organization or agency is responsible for enforcing the restrictions that the
easement document spells out. To do this, the grantee monitors the property on a regular basis,
typically once a year. Grantee representatives visit the restricted property, usually accompanied
by the owner. They determine whether the property remains in the condition prescribed by the
easement and documented at the time of the grant. The grantee maintains written records on the
monitoring visits. The visits also keep the grantee and the property owner in touch. If a
monitoring visit reveals that the easement has been violated, the grantee has the legal right to
require the owner to correct the violation and restore the property to its condition prior to the
violation.
Must an Easement Allow Public Access?
Landowners who grant conservation easements make their own choice about whether to open
their property to the public. Some landowners convey certain public access rights, such as
allowing fishing or hiking in specified locations or permitting guided tours once a month. Others
do not.
If an income tax deduction is to be claimed, however, some types of easements require
access. If the easement is given for recreation or educational purposes, public access is required.
For scenic easements, much of the property must be visible to the public, but physical access is
not necessary. Access generally is not required for easements that protect wildlife or plant
habitats or agricultural lands. For historic preservation easements, either visual or physical access
is required, depending on the nature of the property or building to be preserved.
How Can Donating an Easement Reduce a Property Owner's Income Tax?
The donation of a conservation easement is a tax-deductible charitable gift, provided that the
easement is perpetual and is donated "exclusively for conservation purposes" to a qualified
conservation organization or public agency. Internal Revenue Code Section 170 (h) generally
defines "conservation purposes" to include the following:
To determine the value of the easement donation, the owner has the property appraised both
at its fair market value and at its fair market value with the easement restrictions. The difference
between these two appraised values is the easement value. Detailed federal regulations govern
these appraisals.
An example: A property has an appraised fair market value of $100,000. Mrs. Price, the
landowner, donates a conservation easement to the Southeast Michigan Land Conservancy. The
easement restrictions reduce the property's market value to $64,000. Thus, the value of her gift
of the easement is $36,000. Assuming the easement meets the conservation purposes test, Mrs.
Price - like any donor of appreciated property - is eligible to deduct an amount equal to 30
percent of her adjusted gross income each year for the total of six years, or until the value of the
gift has been used up. If Mrs. Price has an annual adjusted gross income of $60,000, she can
deduct $18,000 a year (30% x $60,000) until she has used up the $36,000 value. In this case,
she will use up the gift in two years (2 x $18,000 = $36,000), if her incomes does not change.
This is just a simple example. Easement donors may qualify for greater tax savings,
especially when state income tax deductions are applicable. Potential easement donors should
seek legal counsel.
How Can Granting an Easement Reduce a Property Owner's Estate Tax?
Many heirs to large historic estates and to large tracts of open space - farms in particular -
face monumental estate taxes. Even if the heirs wish to keep their property in the existing
condition, the federal estate tax is levied not on the value of the property for its existing use, but
on its fair market value, usually the amount a developer or speculator would pay. The resulting
estate tax can be so high that the heirs must sell the property to pay the taxes.
A conservation easement, however, often can reduce estate taxes. If the property owner has
restricted the property by a perpetual conservation easement before his or her death, the property
must be valued in the estate at its restricted value. To the extent that the restricted value is lower
than the unrestricted value, the value of the estate will be less, and the estate will thus be subject
to a lower estate tax. (Note that if the property owner donates the easement during his or her
lifetime, he or she may also realize income tax savings.)
Even if a property owner does not want to restrict the property during his or her lifetime, the
owner can still specify in his or her will that a charitable gift of a conservation easement be made
to a qualified organization upon the owner's death. Assuming that the easement is properly
structured, the value of the easement gift will be deducted from the estate, reducing the value on
which estate taxes are levied. Again, a lower tax results.
Can Granting an Easement Reduce an Owner's Property Tax?
Property tax assessments are usually based on the property's market value, which reflects the
property's development potential. If a conservation easement reduces the development potential
of the property, it may reduce the level of assessment and the amount of the owner's property
taxes.
The actual amount of reduction, if any, depends on many factors. In Michigan, however,
assessors are required to consider the impact of a conservation easement upon the property's
market value.
