Rare
Fern Appears
Last summer while walking his dog in an abandoned gravel
pit in the Blackhawk Forest Preserve in Kane County, Jon
Duerr spied a green shape in the shade of some tartarian
honeysuckle. As Director of Field Services for the Kane
County Forest Preserve District, Duerr's plant identification
skills are darn good, but this one stumped him. He sent
a sample for identification to fern expert Dr. Warren Wagner
at the University of Michigan.
The
finding? Botrychium campestre, from a family of plants
known as grape ferns. Though native to the western prairie,
this species has never been found in Illinois. "I don't
know if the spores blew across that distance on the wind
or were brought here on train cars from the west, but the
fern seems to like the gravely soil of that pit," Duerr
said. "It's just another exciting example of the crossroads
of habitat that typifies Chicago Wilderness."

Voyageur
Canoeists
Musket
shots fired early in the morning of June 12, in Swan
Lake Park, Wisconsin launched a 75-mile Voyageur
Canoe Expedition down the Des Plaines River ending near
Romeoville, Illinois. These canoes, 26 feet long and weighing
300 pounds, are replicas of those used by the original French
Canadian voyageurs, the "truckers" of the fur
trade for hundreds of years.
The
expedition made 21 stops along the way to pick up and drop
off elected officials, agency staff, print media reporters,
and others (including three county board commissioners from
Lake, Cook, and DuPage Counties). Paul Stack, Mayor of Riverside,
announced that "Riverside has always looked at the
river as a liability. Now, we are going to develop the river
as a recreational asset." Gary Mechanic, coordinator
of the expedition, hoped the event would foster alliance-building:
"Paddlers, bikers, runners, birder watchers, fishers
all want the same thing, a continuous greenway and
water trail stretching the length of the Des Plaines River.
We all meet at the water's edge."
The
voyageurs helped kick off the Des Plaines River Watershed
Conference and a proposed Friends of the Des Plaines River.
If you live, work, or play in the Des Plaines River watershed
and want to get involved, contact Gary Mechanic (773) 267-0146

Banded
Killfish
The
banded killifish, known from only eight other locations
in Illinois, was discovered last February in a remote Lake
County bog. Employees from Integrated Lakes Management had
been hired to remove non-native shrubs that were choking
out the bog at Grant Woods Forest Preserve near Fox Lake.
Crew leader Pete Winkler had been noticing thousands of
small fish under the clear ice when one somehow flopped
out through a hole onto the ice in front of him. Recognizing
that the fish was unusual, Winkler took it back to his Gurnee
office, where the firm's director, Jim Bland, identified
it.
"We
were ecstatic," says Bland. "Its presence raises
interesting questions about the bog's connection to nearby
lakes and streams. This might be a relict population, completely
isolated from other killifish." Once common throughout
northern Illinois, the four-inch-long darter is considered
threatened by the Illinois Endangered Species Protection
Board. Reasons for the species' decline are not well understood,
but ecologists point to poor water quality and possibly
unnatural diseases and competition (unintentionally introduced
by anglers who may dump out extra live baitfish at the end
of the day).
Ospreys?
Keep your distance!
The Birds of Illinois asserts that ospreys have not
nested in Cook County in the 20th century. Not, that is,
until now. Like its better known cousin, the bald eagle,
the osprey has made a remarkable comeback in North America
since DDT was banned, and this summer a pair of these fish-eating
birds hatched three young in a stick nest beside a Cook
County Forest Preserve slough. Avid bird monitor Craig Thayer
first saw the downy nestlings on June 21. Although ospreys
generally are tolerant of humans, they are like other
birds still susceptible to nest failure if bothered
too greatly during incubation and brooding.
According
to the Canadian Wildlife Service, "Predation of young
by crows, owls, gulls and raccoons does not usually happen
unless parents have been disturbed by humans." Thayer
hopes that visitors to the site respect these magnificent
birds and will not be tempted to bushwhack their way too
close to the nest site. The birds are easily viewed from
a distance with a spotting scope. Since ospreys show great
site fidelity to an eyrie, they may return to breed in their
Palos region preserve for many years.
The
Second Life of Peck Farm
Citizens
rescued Peck
Farm from bulldozers in 1991, when they voted to approve
funds needed by the Geneva Park District to purchase the
site. Peck Farm was once nationally recognized for its flocks
of pure-bred Merino sheep. Later years saw evolution of
the farm into row crops and a cattle feed lot. The third
generation George Peck family, tired of seeing nearby farmland
converted to housing developments, decided this site could
be a memorial to founder Eli Peck. Landscape architects
and restoration ecologists have been hard at work; native
seed and a prescribed burning program are rapidly reclaiming
nature lost during years of agricultural cultivation. Some
old-fashioned farm gardens will be retained as well.
The
property, located near Kaneville Rd. and Fabyan Parkway,
will feature a 20-acre shallow pothole lake, 88 acres of
planted mesic and wet prairies, seven acres devoted to educational
buildings and open spaces, and 18 acres for recreational
fields. The 1860s farmhouse will contain two public rooms
devoted to history and nature discovery; the corn crib will
be converted to an orientation theater providing an overlook
to the prairie and wetlands, and walking trails will give
visitors a closer glimpse of bluebirds and waterfowl. Peck
Farm, a showpiece celebrating a bygone era and the restoration
of native landscapes, opens in August.

National
Park Quiz
Trick
question: What national park is dominated by oaks, dunes,
and wetlands and has tens of thousands of visitors annually?
Tricky
hints: This park's wide range of flora and fauna surprise
many people, especially because proximity to a major urban
center poses threats, including habitat fragmentation, air
and water pollution, and disrupted ground and surface water.
Surprise
answer? There are two: Indiana
Dunes National Lakeshore and Poland's Kampinoski Park
Narodowy (Kampinos National Park). As of April 15, 1998,
these national parks on the fringes of Chicago and Warsaw
have been designated sister parks. On that day in Warsaw,
officials signed memoranda announcing that the National
Park Service and the Board of Polish National Parks will
exchange personnel, data, technology, training, and experience.
The parks are hoping to embark on cooperative research projects
on hydrology and European bison (saved from extinction and
living in the wild only in Poland's parks).
Fire
Sparks Prairie
It
was only last October that a series of wildfires burned
alongside a stretch of the Chicago and Northwestern railroad
in Barrington, but already a variety of prairie and savanna
plants have taken advantage of them. Since 1850, the easement
of the railway has sheltered native plants from farming
and grazing. This right-of-way continued to be burnt regularly,
by design or accident, as late as the 1960s, maintaining
now-rare prairie and even rarer open savanna ecosystems
alongside the tracks. The 1997 fire, sparked by a faulty
train wheel, ignited dry patches of prairie remnant; it
cleared brush and encouraged the growth of several prairie
and savanna species, including such rarities as veiny pea
and Leiberg's panic grass.
Tom
Vanderpoel, a member of Barrington's Citizens for Conservation,
calls the increase in plant diversity "tremendous,"
and considers the site "one of our best examples"
of the prairie-savanna continuum. Unfortunately, the unmanaged
site has severe problems with aggressive species and will
gradually become degraded unless an agreement with the railroad
concerning management can be reached. In the meantime, Vanderpoel
collects seed from the site and continues to study it.

Head
Start for Turtles
In
early July, 25 immature Blanding's turtles waddled off to
new homes in the DuPage County Forest Preserves. After 10
months of captive rearing at the County's Willowbrook Wildlife
Center, these youths are the second group of captive born
and reared turtles to be released under the District's wildlife
restoration program. District ecologists have been attempting
to restore populations of these rare turtles ever since
they were located in DuPage County during an amphibian and
reptile survey in 1994. Once prevalent in DuPage (and much
of the region), these domed-shell, yellow-throated creatures
have lost much of their original wetland habitat. Moreover,
skunks and raccoons prey heavily upon turtle eggs in today's
small preserves and adult turtles are often run over on
the highways while searching for mates.
"We
feel that we can offset these problems by giving young turtles
a head start that avoids some predation, and through proper
habitat management," said District Animal Ecologist
Dan Ludwig. Rearing young turtles in captivity also accelerates
their growth so that they begin reproducing sooner than
the usual 13 to 18 years. As part of the program, the District's
Department of Grounds and Resources is writing a Blanding's
turtle recovery plan with the assistance of geneticists
and nutritionists from Brookfield Zoo and Blanding's turtle
experts from the United States and Canada.
"This
is the first time the Zoo has applied its population viability
analysis model, used for endangered species conservation
planning around the world, to a local threatened population,"
said Tim Sullivan, Chair of Conservation Biology at Brookfield
Zoo. "We hope this can be a model for how to develop
species management plans for other priority species in Chicago
Wilderness."

Fairway
Frogs
The
gray treefrog never expected to be fussed over by so many
agencies. But a novel collaborative effort (by the Forest
Preserve District of Will County, the Will County Land Use
Department, the USDA Natural Resources Conservation Services,
and Providence Development Corporation) has protected a
vernal pool where this frog breeds. The
Fairways Wetlands Restoration Project, named for the
Fairways Townhomes in Crete, lies adjacent to Goodenow Forest
Preserve.
The
vernal pool, a seasonally wet depression, is just under
an acre in size and 1.5 feet at its deepest, yet provides
valuable breeding habitat for several amphibian species
such as the blue-spotted salamander, the spring peeper,
and the eastern gray treefrog. Most vernal pools like this
one are too small to be protected under the Clean Water
Protection Act and, as a result, developers frequently fill
them in or convert them to larger ponds (where fish may
eat the vernal pond amphibians).
This
site was destined for the same fate until interviews with
nearby residents showed that many moved there to be close
to the forest preserve and have a strong interest in wildlife
and natural settings. These interviews, conducted by the
county Land Use Department, convinced the developers to
approve the restoration proposal. "We're hoping the
project will be viewed as a model to developers, planners,
and researchers," says Bruce Hodgdon of the Forest
Preserve District.

Wild
Turkey (the bird)
Three
Thorn Creek Audubon birders had an exciting morning on June
15 while surveying breeding birds for the Bird Conservation
Network Survey '98. While walking a trail towards the Boy
Scout Camp in Cook County's Zanders Woods, they saw a large
shape in a tree. At first they thought it was a hawk or
a turkey vulture, until birder Daniela Herman spotted the
identifying blue on the head and light-colored legs of a
wild turkey before it flew off into the woods.
"We
were so excited to see such an unusual sight," said
Herman. It is not unusual to find wild turkeys in savannas,
and this is a restored oak savanna, but wild turkeys have
not been recorded in Cook County since 1878, and were considered
extirpated from the state by 1900, according to Chicago
Area Birds. In recent decades, wild turkeys distinguished
from their domestic cousins by their dark rather than white
tail tips have been released in various parts of
rural Illinois to re-establish the turkey as a game bird.
"This
is indeed a significant sighting," said the Illinois
Ornithological Society's Eric Walters. "There have
been only a handful of sightings of these birds in the wild
in northeastern Illinois since they disappeared, and none
that I know of in Cook County."
