Hoop
Dreams, Orchids, and Moths
Late last August, Adam Ralph was playing basketball with
his sister at their Vernon Hills home. When the ball rolled
toward a pile of leaves in the garage, Adam noticed one
rolled-up leaf looked different. He decided it was a bug
and captured it. "He's always capturing creatures and letting
them go, hoping to make a Great Discovery," said his mother,
Joy. After consulting bug books, teachers, and the college
extension service, Adam and Joy were still unable to identify
this curious moth. Finally, the College of Lake County's
Dr. John Mathwig identified the insect as Tersa sphinx,
a species of hawk moth, which are the only moths that can
fly backwards like a hummingbird. Adam was thrilled.
Several
weeks later Joy read an article in Horizons, a Lake
County Forest Preserve publication, about the endangered
prairie white-fringed orchid, which is rare in part because
of a lack of hawk moths, the only insects that can pollinate
it. To restore populations of this species, volunteers pollinate
the orchids with toothpicks, thus mimicking the hawk moth's
long tongue. Joy and Adam contacted the District about their
find, and Frank Drummond, Lake County's wildlife biologist,
paid them a visit. "I was very encouraged," said
Drummond. "Not only does Adam's find offer promising
news for our orchids, but it reminds us all of the wide-eyed
wonder and beauty of our wilderness." Alison

Midewin
Dump Deal?
The
Will County Board and Waste Management Corp. have proposed
a landfill that would raise a 150-foot high wall of garbage
next to the Midewin
National Tallgrass Prairie, home to 19 threatened and
endangered plant and animal species. Hydrologist Charles
Norris testified in public hearings that seepage from the
planned dump would likely contaminate groundwater that feeds
Prairie Creek. The mounds of garbage would also attract
gulls and rats, two predators that might further damage
Midewin's fragile ecology.
The
Midewin National Tallgrass Prairie was created in 1996,
after the Army closed the Joliet Arsenal. US Congressmen
George Sangmeister and Jerry Weller and the Joliet Arsenal
Citizen Planning Commission spearheaded the agreement that
set aside the land for the Prairie. The agreement also contained
provisions for two industrial parks on the developed portion
of the Arsenal's property and 455 acres for Will County's
use as a landfill. The landfill was to accept waste only
from Will County and was to be closed after 20 years. However,
the current proposal would create a landfill three times
the size of the one in the original agreement and the County
would accept waste from a nine-county area.
Opposition
to the enlarged landfill has been led by the Sierra Club,
the Midewin Alliance, and Congressman Jerry Weller. The
Will County Board held public hearings last November, beginning
a period of public comment that ended January 6. The Board
will make a final decision by March 12. For more information,

Good
News for Woodland Birds
According to an ongoing study conducted at the Cook County
Forest Preserve District's Swallow Cliff Woods and other
sites in Illinois, native woodland birds such as redheaded
woodpeckers, Baltimore orioles, indigo buntings, and summer
tanagers are benefiting from habitat restoration efforts.
"Our research indicates that as our woodlands are restored
and maintained through the reintroduction of fire and removal
of invasive plant species, our native woodland bird populations
return and thrive," states Jeffrey Brawn, associate professional
scientist at the Illinois Natural History Survey. "The majority
of bird species do better in the restored areas," says Brawn,
who indicates that the few that do not closed-canopy forest
birds typically require larger intact forests than the fragmented
tracts at Swallow Cliff for successful nesting and rearing
of young. "Our results speak strongly in favor of woodland
restoration as a way to conserve the diversity of our native
bird populations," says Brawn. Brawn pointed out that only
small areas have been restored and studied so far and that
continued research is needed. Shrubland and prairie habitats
were not considered in this study.

Canal
Comes Clean
For
more than 10 years the Illinois and Michigan (I&M) Canal
National Heritage Corridor Civic Center Authority has been
working to improve the Canal in the Willow Springs area.
Unlike the Continental Divide of the great Rocky Mountains,
the I & M Canal crosses a subcontinental divide only six
feet high, but its purpose was mighty, connecting waterways
from the Atlantic (through the Great Lakes and St. Lawrence
River) to the Gulf of Mexico (through the Illinois and Mississippi
Rivers).
Since
its heyday in the early 1800s, the canal has become filled
with silt and clogged with brush. The potential 70 miles
of open trail along its suburban banks motivated several
meetings between the Civic Center Authority, the Army Corps
of Engineers and Congressman Lipinski. The first real progress
was made in Willow Springs in 1997, fittingly during the
Canal's sesquicentennial celebration year. Volunteers removed
more than 200 large deadfall trees and debris, and the Metropolitan
Water Reclamation District of Greater Chicago jet-rodded
several silted-in culverts to improve water flow. "This
is only a tiny step in the right direction," said Stan
Johnson, Director of the Civic Center Authority. "We
need major funding for real improvement." Becky

Citizens
and Sandhills
This past summer, for the first time in living memory, sandhill
cranes nested at Flint Creek Savanna Preserve near Barrington.
Their restored habitat was courtesy of Citizens for Conservation
(CFC). For more than 12 years, CFC has been buying land
and rebuilding wetland, prairie, and savanna communities.
This fall, CFC made an agreement in principle with Premier
Homes to purchase an additional 47 acres of land adjacent
to Flint Creek Savanna. The plan is to create a wetland
within the addition to serve as a retention pond for drainage
of the homes to be built nearby. Former CFC president Waid
Vanderpoel said that CFC has planned a true wetland "rather
than what I call a typical algae pit. We'll do the landscaping
with native aquatic plants." This creative plan allows the
developer to deal with runoff, the human residents to aquire
attractive land nearby, and precious wetland habitat to
be created for many other species. CFC has more than 400
members devoted to conservation in the Barrington area.

Development!
There's
an exciting development underway in Chesterton, Indiana.
Coffee Creek
Center is a 640-acre community that will include 1,200
new homes and 2-3 million square feet of commercial and
retail space. So what's exciting? The developer, the Lake
Erie Land Company, sees this project as an example of sustainable
development and, in keeping with this approach, has already
spent approximately $1.6 million on ecological restoration
there.
Last
December the developer turned over 185 acres to the Coffee
Creek Watershed Conservancy, a non-profit organization assembled
to preserve and manage the development's natural land. The
185 acres border a creek which runs through the property
on its way to Lake Michigan. The Conservancy is comprised
of representatives from environmental organizations such
as Save the Dunes Council, Shirley Heinze Environmental
Fund, and the Northwest Indiana Steelheaders (who work to
conserve fish habitat).
The
Conservancy has been working on developing strict guidelines
for the protection of the site's native plant communities,
including wetland, riparian, prairie and oak savanna. The
Conservancy's land will be open to the public, protected
from development, and restored and maintained as native
habitat. The preservation of this land also serves an important
storm water management role: rain water will be distributed
into the land, allowing it to filter into the creek
there will be no retention ponds. Mike Ryan, vice president
of the Northwest Indiana Steelheaders commented, "Lake
Erie has done a tremendous job. Eventually, hopefully this
will be a model that will expand throughout the watershed."
Conservation Design Forum of Elmhurst, IL prepared the restoration
plan along with J.F. New & Associates of Walkerton, Indiana.

Disappearing
Dams
The
Des Plaines River near Riverside may undergo major changes
soon. As part of its Aquatic Ecosystem Restoration Program,
the Army Corps of Engineers is working with the Illinois
Department of Natural Resources (IDNR) on a preliminary
restoration plan that involves alteration of the Hofmann
Dam between Lyons and Riverside and removal of two nearby
smaller dams. The
Hoffman Dam River Rats Fishing Club has championed the
project, which may help clean up the river, improve fish
populations, open up fish migration routes, and alleviate
some flooding problems. Steve Pescitelli, an IDNR streams
biologist, points to recent studies showing 25 species of
fish below Hofmann Dam and just nine species above, indicating
how drastically the dam affects the habitat. If the preliminary
plan is approved, an in-depth feasibility study would follow.
If the plan is approved, construction could begin within
two years. This could be a model for future dam removals
in Illinois. Andrea Friederici Ross
To
Vote and Preserve
On
April 13, voters in Kane, Lake and Will counties have the
opportunity to approve land acquisition, preservation, and
District improvements through forest preserve bond referenda.
These three counties are growing rapidly, and timely forest
preserve acquisitions can help balance urban development
with open space. In Lake County, the referendum would provide
$55 million in general obligation bonds, $35 million of
which would be for land preservation and $20 million for
habitat restoration, trails and other improvements. In Kane
County, the $70 million referendum would further the goal
of acquiring an additional 5,000 acres of open space and
improve existing forest preserve properties. Will County
Forest Preserve District's $70 million bond referendum includes
plans to designate 72 percent for land acquisition, with
the rest for development and habitat restoration projects
at existing preserves. Alison Carney Brown
Rookeries
Get Help From Will and Cook Counties
Last fall, developers built dozens of homes in the heart
of Lake Renwick
Nature Preserve near Plainfield in Will County. But
these were no typical developers or residents. Volunteers,
most from the Will County chapter of the Illinois Audubon
Society, prepared nesting platforms for the site's many
breeding herons, egrets and cormorants. Lake Renwick has
been a waterbird mecca, providing 44 percent of the state's
nesting areas for the double-crested cormorant, and nearly
100 percent for the cattle egret, according to 1995 data.
"The new nest sites are a great start, but there is
still more to be done to help maintain this important rookery,"
says Audubon's Rita Renwick (no relation to the lake). The
Forest Preserve District of Will County also hopes to do
more for the birds. One plan includes removing fingers of
land extending to some of the nesting islands avenues
that allow raccoons and other predators to threaten nests.
On
February 4, officials and land managers reviewed the preliminary
management plan for another Chicago Wilderness rookery,
along with the lake and lands surrounding it. Like Lake
Renwick, Baker's Lake is struggling with overcrowding, loss
of vegetation from excessive guano, and erosion. Owned by
the Forest Preserve District of Cook County, this island
rookery has been a popular destination for black-crowned
night herons, great blue herons, great egrets and, more
recently, double-crested cormorants. At one time, the preserve
held 220 black-crowned night heron nests, and in 1984, the
site was dedicated as a Nature Preserve primarily to protect
this state-endangered bird. But in the past several years,
their breeding success has decreased dramatically. According
to Ken Wilz, naturalist at Crabtree Nature Center, none
successfully bred at the preserve for the past two years.
Hopefully this management plan will offer black-crowned
night herons a second chance at Baker's Lake, and a better
chance at survival in Illinois.

Respect
for the Native
In September 1998, Highland Park joined the ranks of such
municipalities as Bloomingdale, Naperville, and Long Grove
by officially endorsing the use of native plant species
in landscaping. Weed ordinances in many towns still prohibit
or limit natural landscaping. The new Highland Park ordinance
cites improved wildlife habitat, aesthetic benefits, and
erosion prevention as advantages of native landscaping.
The city also distributed booklets to all residents, with
suggestions for starting a natural garden and ideas for
how to integrate natural plantings in the neighborhood.
For copies of Highland Park's guide, contact Rebecca Grill
at (847) 831-1709 or hagrfg@aol.com.
