Last
fall, as Leslie Borns walked along Montrose Beach
in Chicago, she noticed some striking green stems, bright
red at the base, emerging from the sand near shoreline.
Borns, a volunteer for the Bird
Conservation Network, knew that round, hollow stems
are indicative of a rush, but it wasnt until the plants
flowered this May that she identified it as lakeshore rush
(Juncus balticus). It was the first time this plant
had been found on Chicagos lakefront since 1946! The
plants, similar to grasses and sedges, reach about two feet
in height. Their chestnut brown flowers grow out of the
side of the stems, about halfway up.
The
lakeshore rush inhabits the shallow dune or "panne"
region of a dune formation. One of the first plants to colonize
a sandy area, it grows with other foredune plants, including
sea-rocket (Cakile edentula), a Great Lakes coastal
plant on the Illinois threatened list. Borns has counted
65 clumps of the rush thus far on Montrose Beach. The rushes
bind sand, which forms ridges and swales and leads to further
dune development.
According
to the Lake Michigan
Federation, the lakeshore rush appeared again in Chicago
after more than 50 years due to a number of factors: (1)
The Chicago
Park Districts (CPD) heightened awareness of the
importance of natural habitats, and a practice of allowing
areas of parkland to exist in a natural state; and (2) lake
levels are at an historic low, creating wider beaches and
the shallow dune habitat the lakeshore rush needs to thrive.
The plant cannot survive in areas where it is submerged
or flooded too often and requires a habitat that receives
water periodically and drains quickly. Floyd
Swink, co-author of Plants
of the Chicago Region, agreed that the rushs presence
is probably temporary. Still, he said, "The lakeshore
rush has been absent from the area for so long, it is an
exciting find."
Using
beetles to control invasive purple loosestrife
Purple
loosestrife populations are declining in two Lake County
Forest Preserves, thanks to special leaf-eating beetles
that were introduced to control the invasive weed. Recent
monitoring at the Fox River and Grassy Lake Forest Preserves,
both near Barrington, revealed that the biological control
program using beetles had nearly eradicated the non-native
plant.

Through
a partnership with the Illinois Natural History Survey,
the Lake County Forest Preserves have introduced two European
species of beetles to wetland areas in 12 forest preserves
that were overrun with purple loosestrife, which displaces
native plants and animals. Since 1994, more than 245,000
beetles have been released.
"This
is a long-term control measure that will perhaps not entirely
eliminate purple loosestrife, but it will reduce its cover
and allow native plants and animals the ability to reclaim
their former niches," said Ken Klick, restoration ecologist
and project manager. "The beetles have been so successful
at these sites, you can already see rare gentians, ladies
tresses, and other wetland plants take advantage of the
new sunlight and freedom theyre experiencing."
A
perennial plant, purple loosestrife can grow as tall as
eight feet, and individual plants can produce more than
two million seeds the size of ground pepper each year. Purple
loosestrife plants defy most control efforts, such as hand-pulling,
burns or flooding. Herbicides can be used to treat small
areas but are impractical in large areas, so the beetles
are considered the best method to control large, heavily
infested areas of purple loosestrife.
Educating
the public about loosestrife and other exotic plants is
also contributing to the programs success. Since 1998,
students from 15 Lake County schools have assisted the Lake
County Forest Preserves and local property owners in on-site
rearing programs to help increase the population of beetles.
Schools interested in more information about the program
for beetles should contact the Illinois Natural History
Surveys Beetle Hotline at (217) 333-1005.
Growth
Task Force seeks to control sprawl in Illinois
In
a meeting that was noteworthy for its public consensus on
general growth principles, approximately 30 speakers addressed
a Chicago-area public meeting on July 6. The meeting was
convened by the Growth Task Force, which was recently established
by the Illinois legislature. The task force is composed
of six state senators, six state representatives, and 12
business and community leaders from across the state. Chaired
by Sen. William Maitland, the group includes representatives
from Chicago Wilderness organizations such as the Center
for Neighborhood Technology, the Northeastern Illinois Planning
Commission, and the Openlands Project.
Common
themes that emerged from the meeting were: consistent support
for open space protection; watershed protection; agricultural
preservation; maintenance of existing infrastructure; smart
growth incentives; and, decreasing the states subsidy
of sprawl.
A
critical factor to controlling sprawl is recognition of
the states role in encouraging it. According to the
Illinois Department of Agriculture, 30 percent of farmland
loss is directly attributable to state action, and a significant
but unquantified amount of agricultural conversion is indirectly
caused by state action. One example of the potential for
a good state program to have unintended consequences in
Illinois FIRST, a program whose principal purpose is to
direct public infrastructure spending. If through this program
existing state infrastructure is improved to accommodate
future growth, open space can be preserved. But if Illinois
FIRST is used to build roads, sewers, and schools in undeveloped
areas, sprawl will be fueled and biodiversity further threatened.
The
task force does not have a specific deadline or reporting
requirement, though some members have expressed the wish
to submit smart growth legislation as soon as February 2001.
Comments to the Growth Task Force can be sent to Sen. William
Maitland, 627 State House, Springfield, IL 62706.

Daley
and Ryan team up to protect open space,
stimulate industry in Calumet area
On
June 2, Mayor Richard M. Daley and Illinois Governor George
H. Ryan presented a joint proposal for the Calumet area.
The proposal addresses the future needs of the ecology and
industry in the 20-square mile region. "The Calumet
area is unique in that it will be a region where passive
open space and productive industry coexist," Mayor
Daley said. "We know these uses are compatible, and
with careful planning and management, we can bring back
Calumets natural beauty and industrial strength."
Conservationists
are hopeful about this plan as well. Chicago Wilderness
Chair John Rogner states, "Nowhere has the old attitude
of wetlands as wastelands left a more prominent
legacy than in the Calumet region of Illinois and Indiana.
The challenge is enormous, but the energy and passion seem
to be there," Rogner said.
The
State of Illinois is committing more than $20 million to
the Calumet area, and the city is committing $14 million.
It is hoped these contributions will encourage additional
resources from corporations and foundations. Mardi Klevs
of the US Environmental Protection Agency (USEPA) views
the city and state commitment to the Calumet area as the
right way to do economic development: holistically. "This
plan uses natural resources as an anchor for development.
For 20 years the environmental community has had a vision
for the Calumet area that has now been adopted by government,"
she said. "Thats really powerful."
The
Calumet Area Land Use Plan includes creation of a Calumet
Open Space Reserve that will preserve about 3,000 acres
of wetlands, marshes, and streams. This collection of wetlands
is home to abundant wildlife, including the black-crowned
night heron and the yellow-headed blackbird, both on the
Illinois endangered species list. The list of sites that
environmentalists hope will be purchased, saved, and managed
include Big Marsh, Indian Ridge Marsh north and south, Hyde
Lake wetland, Hegewisch Marsh, Dead Stick Pond, Van Vlissingen
Prairie, Burnham Prairie, and Heron Pond.
The
public open space will be managed collectively to improve
water quality, habitat, and recreational opportunities.
Walter Marcisz, local Calumet bird conservationist, is pleased.
"The proposal has potential to correct a lot of bad
situations we have in Calumet area now," he said. "The
wetlands are so fragmented by roads and other development
that the hydrology is chaotic." For example, he noted,
this year the black-crowned night heron nesting areas are
being drowned out by water that is much too deep, but in
some years the water drops to nothing. "The hydrology
needs to be controlled and regulated."
The
plans also call for building a new Calumet Area Environmental
Center and an energy farm that would produce electricity
from methane collected from landfills and solar panels.
"The environmental center will provide wonderful educational
opportunities for everyone in the area," noted Marion
Byrnes, public affairs director for the Calumet Ecological
Park Association. Byrnes added, "The city and state
have been very receptive to community input."
Over
the past year, the city and state have been meeting with
local industrial, environmental, and neighborhood groups
to help develop the Calumet Area Land Use Plan. The City
has been working closely with the Illinois Environmental
Protection Agency (IEPA), Illinois Department of Natural
Resources (IDNR), and suburban municipalities to enact the
plan. The plan was funded through a grant from the US EPA,
and is one of the largest study areas of its kind. Other
partner agencies providing financial assistance for planning
and development include the IDNR, IEPA, US Army Corps of
Engineers, and the USDA Forest Service.
In
the coming months, the mayor and the governor will be appointing
an advisory committee of local government, business, and
conservation group representatives to ensure that industrial
development and retention, natural area conservation and
environmental cleanup projects are implemented. A number
of roundtable discussions began in August and will continue
to meet throughout the fall. A great deal of research, discussion,
and planning will be done before the end of the year. Chicago
Audubons Alan Anderson summed up the feeling, "Its
been a long time . . . a couple of decades since Jim Landing
founded the Lake Calumet Study Committeebut it looks
like something good is finally coming!" Nicole
Kamins and Alison Carney Brown
Lake
County voters to decide on acquiring and
restoring land, protecting rare species
Lake
County voters will have the chance to acquire and restore
land, protect rare species, and create more trails and other
outdoor recreation and education opportunities by voting
YES for two referenda on the November 7 general election
ballot.
The
first bond referendum would provide $85 million for Forest
Preserve land preservation, acquisition, and improvements.
(Up to $70 million is allocated for land preservation and
acquisition and up to $15 million is earmarked for trails,
restoration, and public access improvements.)
The
second referendum proposes a change in the Districts
corporate tax rate, which has not increased since August
1986, and would fund public safety, maintenance and operation
of new Forest Preserve lands, trails and facilities. The
Forest Preserve District has acquired more than 2,830 acres
since1993 and several improvement and public access projects
are already underway at these sites.
A
recent countywide poll showed that Lake County residents
overwhelmingly continue to enjoy and support their forest
preserves. Most people agreed that the District should preserve
more land, restore habitat for rare plants and animals,
create more trails, and improve access to new and existing
preserves. Respondents also were willing to pay to keep
the current high standards of public safety, maintenance
and operations in their Forest Preserves. "To balance
rapid growth in Lake County, significantly more forest preserve
land is required to accommodate need and demand," said
Carol Calabresa, President of the Lake County Forest Preserves.
"We only have a few years left to preserve our countys
remaining open space as forest preserves, and the time to
act is now."
This
fall, the Lake County Forest Preserves will mail information
about the November 7 referenda to registered voters. For
additional information, Lake County voters can call (847)
367-6640 and ask for Andrew Kimmel or Susan Hawkins.
Skokie
River Partnership launches
collaborative restoration project
The
Skokie River will benefit from restoration thanks to a partnership
between the Park District of Highland Park (PDHP) and the
Lake County Stormwater Management Commission (LCSMC).
The
Skokie River passes through significant public and private
open space in Highland Park. The PDHP saw the array of landowners
as an opportunity for collaborative restoration efforts
and set about to develop a vision for the watershed. In
January, the PDHP and LCSMC secured a Watershed Management
Board Grant to launch the Skokie River Partnership and in
July the partnership retained environmental consulting firm
Hey and Associates. The partnership, still growing, also
includes the East Skokie Drainage District, Bob-o-Link Golf
Course, Old Elm Club, Birchwood Country Club, and the City
of Highland Park.
This
fall, the Skokie River Partnership will consider projects
such as wetland restoration, pond improvements, and detention
basin retrofitsall using native vegetation and sustainable
practices. Recently, the PDHP has secured a grant to do
streambank stabilization with native vegetation at the Sunset
Valley Golf Course.
For
more information on the Skokie River Partnership, please

First
Smith Fellow will work to
implement Chicago Wilderness recovery plan
Dennis
Dreher was recently awarded the first Chicago Wilderness
Smith Family Fellowship for 2000-2001. The primary responsibility
of the Smith Fellow is the implementation of programs and
projects that enhance the conservation objectives of Chicago
Wilderness as outlined in the Biodiversity Recovery Plan.
As Smith Fellow, Dreher will work with local governments
and government agencies to develop model programs that work
to conserve and restore natural areas. He will also serve
as a principal point of contact between Chicago Wilderness
and other regional initiatives, such as the Campaign for
Sensible Growth and the Metropolis 2020 project. The Fellowship
is funded, in part, through a generous grant from the Hermon
Dunlap and Ellen T. Smith Fund of the Chicago Community
Trust.
"The
Smith Fellowship is an excellent opportunity for Chicago
Wilderness to have experienced natural resource professionals
tackle the challenges of implementing the recovery plan,"
said Tim Sullivan, chair, Department of Conservation Biology
at the Brookfield Zoo. "Having Denniss services
for a year will be a tremendous asset for Chicago Wilderness
members and for local governments trying to work on biodiversity
conservation."
Dreher
has a masters degree in environmental engineering
with an emphasis on water resource management and aquatic
ecology. He has worked for NIPC (Northeastern
Illinois Planning Commission) for over 20 years, providing
assistance to local governments and development professionals
on techniques and programs to improve land and water resource
management in the region. Dreher also does volunteer stewardship
work with the North
Branch Restoration Project and the Friends
of the Chicago River.
New
coalition forms to restore Des Plaines River areas
In
February, volunteers founded the Des Plaines River Restoration
Coalition (DRRC) in an effort to improve the natural
areas adjacent to the river in the villages of Lyons, Riverside,
and North Riverside. On their first workday (April 7), it
snowed. Undaunted, more than 50 volunteers wielded loppers
and hand saws to clear Tartarian honeysuckle, buckthorn,
and vines visible above the snow, opening vistas to the
river that hadnt been seen in years. Another group
of 15 volunteers cleared out enough debris to fill six dump
trucks.
This
summer, some 200 volunteers helped out. On May 6, they joined
the Hoffman Dam River Rats for the spring Des Plaines River
cleanup and collected about ten 55-gallon drums of garbage
in addition to old pallets, tires, grocery carts, and a
hot water heater.
Future
DRRC events include:
- October
14 - Garbage clean up. 9:00 a.m.noon
- October
28 - Vegetation management. 9:00 a.m.noon

Coalition, contact Cindy Gustafson, (708) 442-7782 or GustafsonC@pbworld.com.
Storm
opens up canopies for butterflies, flowers, and grasses
The
May 18 storm that brought prolonged power outages to the
north and northwest suburbs of Chicago brought new light
to forest floors when winds up to 84 mph downed hundreds
of trees. The Chicago Tribune described the storm as a microburst
"jets of air that smash against the ground and
spread outward as damaging straight-line winds." While
the resulting damage seemed catastrophic, in the long run
natural communities will adjust and adapt as they do in
the wake of most natural events.

County.

John
Elliott, Director of the River
Trail Nature Center (RTNC) in Northbrook, noted,
"Storm damage, like fire, is the normal scheme of things.
The downed trees have opened the canopy and let in a lot
of light, which encourages plant growth and oak reproduction."
A dramatic
account of the storm, with photographs, is posted
on the RTNC Web site.
Reed-Turner
Woodland Nature Preserve in the village of Long
Grove was closed for more than five weeks; trails became
unsafe when roughly 60 trees sustained damage from the May
18 storm. At the Chicago
Botanic Gardens (CBG) McDonald Woods, more
than 50 mature trees came down during the storm, most of
them oaks.
"It
was the worst storm damage that Ive seen in the 10
years Ive been here, but its part of the disturbance
regime that has occurred in habitats throughout time,"
remarked CBG Ecologist Jim Steffen. "With new openings
in the canopy, the butterfly community will benefit,"
he added. "They like sunny areas for basking and the
sunlight encourages the herbaceous growth that butterflies
feed on."

Study
recommends reducing wooded borders
between fields to help grassland birds
While
the decline of grassland birds is well documented, how to
manage their prairie habitat to help reverse the birds
decline is the subject of important new research. Under
the auspices of the University of Illinois at Chicago, Charles
H. OLeary and Dennis W. Nyberg have recently completed
a study on land management for area-sensitive grassland
birds. Their paper, "Treelines Between Fields Reduce
the Density of Grassland Birds," was published
in the July issue of Natural
Areas Journal.
Conducted
in five fields dominated by pasture grasses within Cook
Countys Poplar Creek Forest Preserve, the study evaluated
grassland bird use among them. The area ranged from 2.2,
to 16.3 hectares. All species with singing males in each
of the fields were counted at least once a week from April
15 to July 15 between 5:30 and 10:30 a.m. in 1995 and 1996.
The grassland species identified were: savannah sparrow,
grasshopper sparrow, Henslows sparrow, eastern meadowlark,
bobolink, and sedge wren. Grassland bird usage within fields
was evaluated by mapping their territory and nest locations.
Usage patterns in relation to the field edge were also examined.
OLeary
and Nyberg note, "Within complexes of fields, our study
documents that these birds chose larger fields over smaller
ones. At Poplar Creek, each bird of the five area-sensitive
species probably had knowledge of all five fields, but only
the larger ones were chosen."
Observations
such as these led OLeary and Nyberg to make the following
management recommendations for Poplar Creek: (1) reduce
woody vegetation within fields, (2) reduce woody vegetation
separating small fields from large fields, and (3) connect
large fields to one another to reduce edge and increase
nesting (interior) area.
These
recommendations lend support to the green paper "Conserving
Local Habitat for Declining Grassland Birds,"
published in April by the Chicago regions Bird
Conservation Network (BCN). The paper, by Duane Heaton,
builds the case for improving grassland bird habitat: "In
grasslands, the impact of nest predation near woody edges
has been shown to extend at least 50 yards into some habitat
blocks (Johnson and Temple, 1990). It is not uncommon for
more than 80 percent of nests (near edges) to fail to produce
young birds (Herkert, et al., 1993)." The BCN paper
also includes a 14-point management guideline for enhancing
habitat for grassland birds.
Glenview

Station Prairie.

On
March 7, the Glenview Village Board voted to name the 31-acre
prairie at the redeveloped Glenview Naval Air Station "Air
Station Prairie" in recognition of the role played
by the Navy in inadvertently protecting it. The Board also
recognized the work of Glenview resident Evelyn Pease
Tyner by naming Air Station Prairies future interpretive
center after her.
Through
her photography and environmental advocacy, Tyner was instrumental
in protecting The Grove National Historic Landmark
and the James Woodsworth Prairie Preserve in Glenview,
Illinois. Tyner is a former professor at Harold Washington
College with a Ph.D. in biochemistry.
The
Village hasnt developed plans for the interpretive
center yet. "When the planning process begins, we will
have to give input to be sure the center doesnt encroach
on the prairie," Tyner noted. After four years of management,
including three prescribed burns, Air Station Prairie currently
boasts 156 native plants species, including the state-endangered
mountain blue-eyed grass and golden sedge.

Willowbrook
Wildlife Center to the rescue
You
awake one morning to find a Coopers hawk tangled in
your rose bush, barely alive and too weak to fly. Who ya
gonna call? For the citizens of DuPage County the answer
is simple: the Willowbrook
Wildlife Center.
By
June of this year, the center had taken in more than 2,000
animals. Of these, 673 were returned to the wild after examination
or released after treatment, including two amphibians, 14
reptiles, 291 mammals, and 366 birds. Only native species
are accepted at the center; others are referred to private
citizens who rehabilitate non-native species.
According
to Carl Strang, naturalist at the 50-acre center for 18
years, Willowbrook staff members cannot make house calls,
so they rely on concerned people to bring the animals in
for treatment. Once admitted, patients are examined by staff
veterinarian Dr. Katie Brown and her staff of several student
interns and 14 rotating volunteers (who must have at least
a years experience in wild animal care in other parts
of the Center before working in the clinic). Each animal
is provided care and medical treatment and is, if possible,
rehabilitated and reintroduced into its native habitat.
"I get personal gratification from helping individual
animals, which many times have been injured through interactions
with the public," Dr. Brown says, "but also from
helping educate the public on how to improve their relationship
with wild animals."
Strang
explained that rehabilitation is sometimes not possible,
as in the case of the great horned owl injured when an excavator
it was hiding in started up. The construction crew brought
it to the clinic but its shoulder was so damaged it had
to be euthanized.
According
to Willowbrook Curator Marcy Rogge, "The impact the
center has on animal populations is secondary. Whats
most important is our impact on humans. Our goal is to become
mediators between people and animals, to have a long-term
impact on peoples attitude toward nature." Located
in Glen Ellyn, Illinois, the Center is open seven days a
week, 9:00 a.m.5:00 p.m. Telephone assistance is available
daily, 9:00 a.m.4:30 p.m. Before attempting to help
or touch wildlife, call the center at (630) 942-6200.

Conservation
and Reinvestment Act clears Senate committee
In late July, the Conservation and Reinvestment Act (CARA)
successfully passed the Senate Energy and Natural Resources
Committee. As this issue goes to press, the bill must still
pass the full Senate, and then a conference committee must
resolve minor differences with the previously passed House
bill. The administration has already indicated its support.
Many
people consider this bill one of the most important pieces
of conservation legislation in decades. It will provide
major funding for wildlife, land and water conservation,
parks and recreation, and coastal rehabilitation-paid for
by federal revenues from oil lease drilling on the outer-continental
shelf. Calling for annual appropriations of almost $3 billion
nationwide, the bill could mean as much as $53 million per
year for Illinois.
Senator
Peter Fitzgerald, who aided CARAs passage, told
Chicago WILDERNESS that "Our countrys pristine
forests, parks, and wetlands belong to every U.S. citizen.
They are our national treasures. This legislation will help
protect these lands in Illinois and across the United States."
"This
is a big step towards a major win for conservation,"
said Steve Packard, National
Audubon Society director for the Chicago region. "Thanks
go to good leadership from Senator Fitzgerald and a variety
of conservation groups. Locally, the Bird
Conservation Network gets special credit. This is a
good example of democracy working. We can expect to see
great habitats acquired and great public education programs
from this substantial funding."
Consider
what CARA could mean to this region in the coming years:
- $800,000
- $1,000,000/yr for beach management at Illinois
Beach State Park and to protect, manage, and restore
this unique dune and swale community.
- Acquision
of key in-holdings at Shawnee
National Forest (to reduce forest fragmention).

Local
groups win award for Chicago River watershed project
Friends
of the Chicago River (FCR) and the Lake
County Stormwater Management Commission (LCSMC)
were recently awarded the 1999 CF Industries National
Watershed Award for their North Branch of the Chicago
River Watershed Project. The award, administered by
The
Conservation Fund, recognizes innovative, nonregulatory
approaches to improving water quality and emphasizes local
partnerships that demonstrate successful economic incentives,
voluntary initiatives, and education.
In
1996, FCR and LCSMC joined to develop strategy and implement
best management practices and programs to address nonpoint
source pollution and flooding; to protect and restore natural
resources; and to educate and involve citizens and community
leaders in the watershed planning process and river stewardship.
The partnership has since accomplished: the North Branch
Chicago River Watershed Plan; Voices of the Watershed; Chicago
Rivers School Network; Mellody Farm Floodplain Restoration,
and the North Chicago Multi-purpose Detention Basin demonstration
projects; numerous other ongoing initiatives.
In
the "Runoff Report," FCR and the LCSMC said they
realized long ago that the only way to solve the Northeastern
Illinois watersheds mushrooming problem was to enlist
everybody who lived and worked there from homeowners
to teachers to businesses to local governments to
voluntarily work together to protect their watershed.
To
get involved in this award-winning vision, call Cynthia
at Friends of the Chicago River, (312) 939-0490. ext. 13,
and Sean Wiedel, Lake County Stormwater Management Commission
Watershed Planner, (847) 918-7693.
Software
for tracking plants to assess quality of open land
What
better way to assess the natural quality of open land than
to take a closer look at the plant species that live there?
One such methodcommonly referred to as Floristic
Quality Assessment (FQA)does exactly that and
is now available in a Windows-based software program. Two
databases are currently available: one for the State of
Illinois and another for the Chicago region. Future databases
will likely include Iowa, Michigan, Missouri, northeastern
Ohio, the northern Great Plains, and southern Ontario.
FQA
is a method designed to assess the quality of open land
using existing plant species. It allows landowners, conservation
organizations, volunteer stewards, and other practitioners
to make standardized comparisons between natural areas and
facilitates the development of conservation programs by
tracking and analyzing site monitoring and restoration activities.
For additional information about the FQA Program and its
use, contact Conservation
Design Forum at (630) 758-0355. All profits from
the sale of the program support the work of the Conservation
Research Institute.
Herons establish
new rookery in Lake County Forest Preserve
Wildlife
biologists were recently surprised to discover a new large
heron rookery in the Lake
County Forest Preserves (LCFP) during an annual
survey of cranes, herons, and other large waterbirds. Made
up of 24 great blue heron nests, the rookery was spotted
from a helicopter by biologists for the LCFP and the Illinois
Department of Natural Resources (IDNR).
The
biologists spotted the natural rookery while checking manmade
platforms at another forest preserve site. "Herons
traditionally nest in the same area for a number of years
and its unusual to see them choose a new nesting site,"
said Frank Drummond, LCFP wildlife biologist. "Apparently,
they were attracted to suitable nest trees near a large
wetland, which provides ideal feeding grounds for herons
and a variety of other wildlife and waterfowl." This
discovery brings the total number of great blue heron nests
located within four Lake County preserves to 104.
The
annual survey, known as the crane count, has been conducted
throughout Illinois for over 10 years by the IDNR. It focuses
primarily on sandhill cranes, a rare species, but also counts
more common wading birds such as herons, egrets, and cormorants.
In
addition to the heron count, biologists observed three nesting
pairs of sandhill cranes at three Lake County preserves.
Approximately 175 great egret nests and 60 double-crested
cormorant nests were also identified.
To
participate in the crane count and other volunteer efforts
to help wildlife in LCFP, call Tom Smith, volunteer stewardship
coordinator, at (847) 968-3329.
New
members join Chicago Wilderness coalition
Seven
new members were voted into Chicago Wilderness at the July
11 Council meeting, expanding the coalition to 114 members.
- The
mission of Lake Bluff Opens Lands Association is
to protect, preserve, and restore open space and natural
areas in and around the Village of Lake Bluff. The association
is currently working on restoring native flora to a large
area of ravine, as well as the restoration of a sand community
at Lake Bluff beach.
- The
Northwestern University Environmental Council serves
to support, coordinate, and stimulate a wide range of
environmental university research and educational programs.
Many of these programs involve work that supports biodiversity
in the Chicago area.
