Detroit—what do you think of when you hear that name? Auto industry?
Steel? The sounds of Motown? Makes sense. But, for a growing number of
people “Detroit” calls to mind the river that flows past the
city's front door and forms the boundary between the United States and
Canada. Unfortunately, this river has been unmercifully abused by humans,
but nevertheless, it retains tremendous potential to benefit wildlife,
fish, and people.
The Detroit River has paid a tremendous price for what humans call “progress.”
Indeed, most of what was natural in and around the Detroit River is now
gone. When Antoine de la Mothe Cadillac established Detroit in 1701, the
river had extensive marshes along its banks and a diversity of adjacent
upland habitats. Today, 95 percent of the historical coastal wetlands
have disappeared under fill, steel, and concrete pilings. Several islands
in the river have been altered, eroded, or used to dispose of contaminated
river sediment and industrial waste. Invasive plants, fish, and mussels
also have contributed to the river’s degradation. Yet, special places
still exist and can be restored alongside the high rises, stadiums, and
smoke stacks.
The Detroit River International Wildlife Refuge was born of a vision
shared by a group of local governments, corporations, and conservation
organizations from the United States and Canada. It became a reality when
President George W. Bush signed Public Law 108-23 in December 2001. The
law established an acquisition boundary for the refuge in the United States
and also designated three small river islands, once part of Wyandotte
National Wildlife Refuge, for inclusion. The new refuge’s habitats
include islands, coastal wetlands, marshes, shoals, and riverfront lands
along 42 miles of the lower Detroit River and western Lake Erie in Michigan.
The law calls for the U.S. Fish and Wildlife Service (Service) to establish
partnerships with Canada and local communities and to enter into cooperative
land management agreements with private landowners. To that end, the Service,
Michigan Department of Natural Resources, and Environment Canada are currently
developing a Comprehensive Conservation Plan (Plan) to guide the refuge
for the next 15 years.
The habitats protected and restored by the refuge will provide a hospice
for 65 fish species and some 300 species of migratory birds, including
29 waterfowl species. The lower half of the river sits at the intersection
of the Atlantic and Mississippi Flyways and connects Lake St. Clair to
Lake Erie. Some 3 million migrating waterfowl naturally follow the western
shoreline of Lake Erie, where they stop to rest and feed in the river
and in its nearby marshes. Over 300,000 diving ducks, primarily canvasback
and greater and lesser scaups, feed in the river’s wild celery beds.
The 1986 North American Waterfowl Management Plan included the river’s
ecosystem in one of its 34 waterfowl habitat areas of major concern. The
river’s importance to wildlife and people is further reflected by
two national designations: American Heritage River and Canadian Heritage
River. And, several marshes along the river’s lower region are Western
Hemisphere Shorebird Reserve Network sites.
The Canadian government has not designated formal boundaries for a sister
refuge, but conservation efforts on the Canadian side of the river are
being guided in concert with the refuge’s goals and the binational
Conservation Vision for the Lower Detroit River Ecosystem. Environment
Canada has been working in partnership with the Service and Canadian agencies
to achieve a compatible and shared focus for fish and wildlife habitat
conservation.
The forthcoming Plan will provide guidance for inventorying resources,
will include recommendations regarding the conservation of remaining coastal
habitats, and will identify ways in which industry, local governments,
and private landowners can enhance their lands to benefit wildlife. Meanwhile,
collaborative habitat protection and restoration work is underway in several
locations. For example, in the United States a cooperative management
agreement has been signed to restore habitat on a 500-acre nuclear energy
facility, and the U.S. Army Corps of Engineers is transferring property
to the refuge for protection.
A positive view for the future of the Detroit River and Lake Erie’s
western basin reflects an abiding faith in nature. Do we look at what
has been lost, wring our hands, and give up? Or, do we identify what remains
and what we can recover, value it, and work for its preservation? Our
positive outlook is influenced by the persistence of wildlife: despite
the almost complete conversion of the river’s banks to concrete
and steel, despite the loss of nearly all the coastal wetlands, and despite
decades of industrial pollution, the birds still come, as they have for
millennia, looking for what they need to survive—we can’t
let them down.

An Unexpected Dividend
by Lew Crouch, Cheeha-Combahee Plantation
Shortly after the end of World War II, the owners of Cheeha-Combahee
Plantation on South Carolina’s lower Combahee River embarked on
a business venture that would affect thousands of waterfowl, wading birds,
shorebirds, and other wetland-associated species for more than a half-century.
With a goal of recovering operating costs, the owners developed a business
plan, one element of which was to invest in the building of a 1,500-acre
impoundment in the river’s brackish tidal marsh. By constructing
banks, ditching, and controlling water levels, they established a pasture
area in which to raise beef cattle, which would be sold to help offset
the plantation’s operating expenses. For 15 years, that impoundment,
known simply as “Magwood,” served the grazing needs of several
hundred head of cattle.
As you might expect, though, the plan went afoul as the law of cause-and-effect
came into play. The prolonged drying out of the wetland caused the soil’s
pH to plummet, and the marsh grasses needed to maintain the pasture began
to die. By 1962, the Magwood bovine project was abandoned. There was a
silver lining, however. The owners used the same mechanisms that had been
employed to convert the wetlands into pasture to transform Magwood back
to a brackish-water marsh. For many years thereafter, the rehydrated impoundment
was a magnet for thousands of ducks, ibises, egrets, and herons. Magwood
remained as such until the early 1990s, when the plantation changed hands.
A second silver lining appeared: the new owners—eight individuals—had
an interest in wetland habitat management. They made extensive repairs
to the impoundment’s banks and installed new water-control structures
to enhance wetland management.
Magwood has been an important wintering area for migratory waterfowl,
such as northern pintail and American black duck, but its habitat quality
had seriously declined over the 50 years of manipulation. In 2001, a third
silver lining was found behind the habitat-quality cloud. The plantation’s
owners wanted to further improve the marsh and engaged others to help.
The partners received a $22,445 North American Wetlands Conservation Act
grant to which they added $26,270. They used the funds to renovate miles
of ditches that had been dug 50 years earlier, excavate new ditches, and
install another water-control structure. These changes enhanced the owners’
ability to manage Magwood’s water and salinity levels to obtain
the desired vegetation.
The improvement in water quality and subsequent enhancement of marsh
vegetation was noted almost immediately. While visits by traditional migrants
such as American wigeons, gadwalls, glossy ibises, American bitterns,
and southern bald eagles continued during the winter of 2001-2002, there
were also newcomers: white pelicans. Spring and summer visitors also seemed
to approve of the marsh’s renewal. Nesting use by several species,
including black-necked stilts, least bitterns, willets, and mottled ducks,
and feeding use by wood storks, black terns, and Forster’s terns
has increased.
There is a moral to this story: what may be a disastrous financial investment
for one can mean profits and big dividends for another. In this case,
it’s a payoff for the birds.

Safety in Numbers
by Ed Swan, Vashon-Maury Island Land Trust
Washington State’s 96-square-mile Vashon Island is a rural outpost
in the middle of highly developed central Puget Sound. Like Sherman's
march to the sea, urban sprawl from Seattle to the east, Tacoma to the
south, and Bremerton to the west has devoured much of the sound’s
natural landscape. To the north, Bainbridge Island, with a bridge to the
mainland, has nearly succumbed as well.
Vashon Islanders, aware of the advance, feared for their island home
and bucolic lifestyle. At the end of the 1980s, a group of residents formed
the Vashon-Maury Island Land Trust (Land Trust) to preserve some of the
best wetlands and salmon habitat remaining in the sound’s central
region. High on their priority list was the Christensen Creek watershed,
including its headwaters, Christensen Pond. In the 1990s, the Land Trust
assembled a coalition of several landowners to protect more than 100 acres
along the creek, working toward creating a patchwork of conservation easements
and county open space that meanders to the pond’s property. Then,
in 2001, a miracle happened: the 30-acre parcel that contained the pond
was offered for sale.
"It was a neighbor who notified us about the availability of the
30 acres and the pond," said Donna Klemka, a Land Trust board member.
"We moved quickly to purchase what is now called the Christensen
Pond Bird Preserve. We have been able to preserve the hydrology and habitat
of a huge section of the watershed, including an easement at the estuary,
significant riparian areas, and the pond. The preserve is a piece of heaven.
As you step off the road toward the south-end ferry, you are embraced
by the wood’s greenery and birds’ songs."
The Land Trust and its partners received a $47,200 North American Wetlands
Conservation Act grant in 2002 to help purchase the property. The partners
raised $414,200 more to close the deal.
The 5-acre pond and its 20 acres of associated wetlands have been undisturbed
for decades. These habitats are crucial to sustaining the island’s
surface-water supply and to recharging the island’s sole aquifer.
They are also important to a myriad of wildlife species. The pond provides
good habitat for amphibians, and the creek offers nursery habitat for
salmon and a playground for otters. The pond’s size and isolation
make it ideal breeding habitat for hooded mergansers and wood ducks. The
mixed coniferous/deciduous forest adjoining the pond appeals to many neotropical
migrants. Four warbler species, Wilson’s, orange-crowned, Townsend’s,
and yellow-rumped, and the Pacific-slope flycatcher are common in the
preserve. Rufous hummingbirds and band-tailed pigeons, both on the Audubon
Society Watch List, also inhabit the woods. Great blue herons and bald
eagles drop in on the pond for a snack, and at night, barred owls prowl
through the woods. Fifty-four bird species have been spotted on the preserve.
The project’s measure of success can be accounted for in many ways.
Its benefits to wildlife are an obvious measure, but the effect it had
on uniting the island’s residents to protect something dear to them
may top the list.

Mother Nature: An Industrial Application
by Tony Pace, Parsons Corporation
Although the sun has been up for almost an hour, it’s just now
rising over the bluffs along southwestern Ohio’s Great Miami River.
It’s mid-June and the fog is beginning to lift from over a pond
and its adjacent wetlands. Swallows are busy at work, swooping and dipping
into the still water. A red-winged blackbird sits atop a cattail singing
his morning song. The sounds of what seems to be a babbling creek can
be heard among the peeps, chirps, croaks, and whistles of the birds, frogs,
and other wildlife. A doe and her fawn wander through the landscape and
contentedly nibble on new vegetative growth.
You’re probably surmising this is a scene from some remote stretch
along the river. It’s actually a fairly typical day at ChevronTexaco’s
former Cincinnati Refinery, which now contains a constructed treatment
wetland. The site sits on the outskirts of suburbia, only 17 miles west
of Cincinnati. Built by Gulf Oil Corporation, the refinery began operating
in 1931. Chevron acquired it, along with a half-century’s build
up of hydrocarbon-based contaminants, during its merger with Gulf Oil
in 1985. In 1986, Chevron ceased production at the 45,000-barrel-per-day
operation. Various decommissioning and remediation activities have been
under way since then, the most significant being the installation of a
several-million-gallon-per-day groundwater pumping and treatment operation.
As is often the case, necessity is the mother of invention. In this case,
however, necessity was the mother of utilization. The existing settling
pond was slated for decommissioning as part of remediation activities,
and an alternative was required. In this day and age, new wastewater technologies
are continuously being developed. However, ChevronTexaco opted to use
a pond/wetland system, a technology pioneered by Mother Nature. The system
consists of a series of gravity-fed ponds. The first pond acts as a settling
pond to remove solids. The other two, constructed in parallel, are much
shallower than the first and filled with native wetland plants that “polish”
the water prior to discharge. The main difference between a constructed
treatment wetland and a natural wetland is that the former is designed
to treat pre-processed wastewater and the latter typically treats storm-water/agricultural
runoff.
Having been in operation for a little over a year, we celebrated the
wetlands’ construction during the spring of 2003 with the first
of hopefully many wood duck hatches. Three broods were discovered in June,
comprised of 8 to15 ducklings each. Raptors also have been found in the
wetlands, including American kestrels and a breeding pair of red-tailed
hawks. The habitat complex attracts resident species as well. Serving
as a nursery of sorts, there have been regular sightings throughout the
complex of deer, rabbits, and wild turkeys with their offspring. White-tailed
deer doe are especially appreciative of the tall, warm-season grasses
and forbs planted around the complex’s perimeter, as it gives them
a secure place to leave their fawns as they browse. Approximately 300
trees and shrubs were planted to provide food and shelter for wildlife.
In replacing an aging wastewater treatment facility, ChevronTexaco has
returned wetlands and grassland prairie to a nearly century-old industrial
site.

The Heart of a Community
by Thomas Abello, The Nature Conservancy
What does it take to protect the heart of a community? That’s what
the people of Parsonsfield, Maine, population 1,500, were asking themselves
when 8,600 acres of forested lands that had added to the quality of their
lives were slated to be auctioned off as several parcels. At stake was
the largest block of managed forestland south of Sebago Lake: the Leavitt
Plantation Forest.
The prospect of fragmenting this forest was staggering. For generations,
it had provided forestry-related jobs—significant to the local economy—and
opportunities to hike, hunt, fish, and snowmobile—equally significant
to the locals’ lifestyles. Subdividing the forest did not bode well
for wildlife. From moose to bobcat, from American bittern to wood duck,
the loss of habitat spelled “problems.”
The town’s residents were not alone in their concerns. Thanks to
Renewable Resources, a timber management company that wanted to buy the
land intact and keep it in production, an opportunity arose to forestall
the auction and save the forest. But to do so, the company needed some
financial help. . .the kind it could get by selling a conservation easement
to protect the forest’s ecological values.
That’s where a coalition of public and private organizations led
by The Nature Conservancy (Conservancy) entered the picture. The Conservancy
approached the Maine Department of Conservation to see if it was willing
to take title to an easement on the property. It was, if its covenants
required sustainable forestry practices, protection of native wildlife,
and public access for traditional recreational uses. The next step: negotiating
the easement and raising $2.8 million to pay for it.
The town’s residents got the ball rolling when they voted to have
$50,000 of their tax revenues allocated to saving the plantation. As it
turned out, this was the foundation upon which success was built. Many
stepped forward to make personal contributions—the Conservancy and
Parsonsfield-area residents amassed another $575,000.
With nearly 800 acres of wetlands on the property—ideal habitat
for migratory songbirds such as veery, purple finch, and chestnut-sided
warbler—the partnership then applied for a $50,000 North American
Wetlands Conservation Act grant, which they received.
The partnership continued to grow. The board of Land for Maine’s
Future, a state-funded conservation program, liked what was happening
and joined in with $1.2 million. The Maine Outdoor Heritage Fund contributed
another $50,000, noting the overwhelming support of selectmen, planning
board members, county commissioners, local businesses, outfitters, and
educators.
With such active support of the area’s citizenry, this story shouldn’t
only be about raising money, but there’s one more pecuniary chapter:
$600,000 more was needed. The State sent a proposal to the USDA Forest
Service for a $600,000 Forest Legacy grant. A celebration followed, as
the awarded grant assured that the plantation would remain unfragmented,
providing good homes for wildlife, access for the public, and opportunities
for sustainable forest management.
In the end, a town is tied to the fate of its lands. For Parsonsfield,
generations to come will be able to explore the wonders of the Leavitt
Plantation Forest. They can thank a broad-based partnership that blended
the strengths of all the organizations and people involved.
