One
Step Ahead Of The Bulldozers
Last spring, Bob LeFevre of Barrington-based Citizens for
Conservation (CFC) heard of a soon-to-be-developed property
in Lake Zurich that was home to yellow star grass (Hypoxis
hirsuta), a dainty member of the amaryllis family. Tom
Vanderpoel located the grass, whose bright stars had just
bloomed, surrounding a bulldozer, brush cutter, and trucks.
A quick conference with the equipment operator led to a
rescue plan. The next day, CFC volunteers worked frantically
because in more than a decade they had never encountered
yellow star grass in such numbers (nurseries do not even
offer the seed). They dug about 75 plugs, each containing
a few yellow star grasses plus the bonus of intermixed
blue-green sedge, ideal for some of CFC's wet prairies.
"I've
got an old beat-up truck I keep for prairie restoration,"
said Jerry Masino, a long-time volunteer. "We had short
notice and we were just a few steps ahead of the bulldozers.
That's the way it goes with progress." A rough estimate
indicates that CFC volunteers brought as many as 300 of
the little amaryllises, along with 500-600 sedges, to safe
new homes at Grisby Prairie and Flint Creek Savanna. LeFevre
says the plugs are doing very well, "It's virtually
impossible to get these plants any other way. You can't
get the seeds once the flower is gone it's almost
impossible to find them. These plants are protected now
and we hope they'll spread."

Queen
For A Day
"It
was truly amazing! Thrilling!" Chicago WILDERNESS
magazine contributor Carol Freeman couldn't decide if she
was more surprised by finding the only queen butterfly seen
in Illinois in over 70 years or by finding herself on the
front page of the Sunday Chicago Tribune.
"I
was excited that the Trib followed my story and expected
to find it in the Style or Home and Garden sections,"
said the professional photographer and graphic designer.
But the paper splayed it up front, thrilling Freeman and
educating thousands about her "once-in-a-lifetime"
find. "Whenever I'm in nature, I always see something
I haven't seen before, and each time, I take as many pictures
of it as I can," said Freeman. Then she goes home and
uses the photos to identify the subject in question.
So
when Freeman saw an unusual butterfly at the Chicago Botanic
Garden on July 18, she followed it and snapped away. Puzzled,
she called Chicago WILDERNESS editor Debra Shore,
who referred her to Doug Taron, curator of biology at the
Chicago Academy of Sciences. Taron confirmed that it was
a queen butterfly (Danaus galippus), a relative of
the monarch that lives in the far southern parts of the
US and has been spotted in Illinois only once before
in 1928. Taron noted that this is not the only southern
lepidopteran to make an unusual appearance in Illinois this
year. Butterfly Monitoring Network volunteers spotted the
funereal duskywing and white M hairstreak (which only gets
to the Chicago region a couple times a century). Plus they
saw unusually large numbers of firey skippers and buckeye
butterflies (which migrate through this region, but normally
not until mid- or late July).
While
this may sound like evidence of global warming, the scientific
community is not so sure. Chris Dietrich of the Illinois
Natural History Survey and Taron point to many other possibilities
explaining these unusual sightings: a mild winter can allow
insects to overwinter farther north than usual; storm systems
can blow insects out of their usual ranges; and shipments
of nursery stock or even family cars can carry immatures
and adults far from home. "It is a stretch to attribute
this to global warming, unless we see many of these southern
species for several years in a row," said Dietrich.
Land
For Experiments
Calling
all bug counters, soil scientists, prairie lovers, and others:
If you're looking for experimental land space, Fermilab
may be your new laboratory. Fermilab is the site of the
Department of Energy's smallest (and least-polluted) National
Environmental Research Park (NERP), and now NERP staffperson
Rod Walton has announced that portions of Fermilab's 6800-acre
site are being made available for scientific projects fitting
NERP's mandate: to study the impact of human activities
on the environment in various ecoregions.
Since
the radical plan to create a prairie at the lab, was launched
in 1975, Fermi has been a place of cutting-edge experimentation.
For the last 15 years, Argonne National Laboratory scientists
have studied soil dynamics of prairie restoration there.
And now they're examining carbon sequestration in the soil
to help understand the threat of global warming due to greenhouse
gas accumulation. The Morton Arboretum has used the site
to study re-introduction of the American hazel. Others have
studied the dynamics of mammalian populations and plant
resistance to insects.
Walton's
wish-list for future research includes continuing prairie
restoration experiments, as well as baseline surveys of
the plant, insect, fish, and mammal populations. Professionals,
volunteer groups, and citizen scientists with these or other
interests are invited to submit proposals. For more information,
contact Rod Walton at (630) 840-2565.
Millennium
Grass
Imagine
Cranberry Slough Steward Dennis Nyberg's surprise in July
1998, when he identified a small patch of narrow melic grass
(Melica mutica) at this forest preserve site in southwestern
Cook County. According to his dog-eared 1994 edition of
Swink and Wilhelm's Plants of the Chicago Region, this rare
woodland grass has not been documented in this region since
1899. It was considered locally extinct. Steward at the
site for 16 years, Nyberg said, "The find indicates
that once stewardship takes place, our native biodiversity
has potential to flourish. I'm pretty sure that burning
this area a couple times allowed this grass finally to flower
and be recognized."
A
biology professor at the University of Illinois at Chicago,
Nyberg received permission from the Illinois Nature Preserves
Commission to collect seeds of the plants. A small portion
of the seeds from each stalk, about 100 in all, now await
the spring in cold storage. As the calendar turns 2000,
they will be placed in a moist, sterile soil mix, and in
April they will be brought to room temperature to germinate
in trays at the UIC greenhouse. Next they will be potted
individually and later planted in a garden partly shaded
to simulate an oak woodland. After two-to-three years, the
plants should produce seeds of their own. Nyberg then intends
to seek permission from the Commission to plant the seeds
at Cranberry Slough, expanding the existing population and
establishing a second one.

Greening
Chicago
Inch by inch, square foot by square foot, the City of Chicago
is getting greener. In July the City Council passed a revised
landscape ordinance requiring property owners and developers
to take a bigger role in installing and maintaining larger
planted areas. Parking lots are a prime focus for greening.
The old ordinance required parking lots to be set back five
feet; this one requires a seven-foot setback, meaning more
unpaved land. Large "vehicular use areas" must
be landscaped on a larger percentage of their total area.
Not
only will these provisions improve the beauty of the Windy
City, they will help manage storm water by increasing permeable
surfaces, thereby reducing flooding and dependence on projects
like Deep Tunnel. The ordinance will help air quality, too,
as more vegetation is planted as part of landscaping requirements.
To ensure that these positive effects continue, the revised
law makes parkways, previously the maintenance responsibility
of property owners for only 5 years, now their responsibility
forever. Chicago is becoming, little by little, an even
more hospitable place for plants, people, and other critters.
Audubon
Acquisition
In
its second major acquisition within months, the Illinois
Audubon Society purchased in McHenry, County
Black-crown Marsh in June. Located between Moraine Hills
State Park and the Lake County border, the 80-acre marsh
provides nesting habitat for the state-listed black-crowned
night heron, black tern, sandhill crane, pied-billed grebe,
common moorhen and yellow-headed blackbird. The endangered
American bittern and great egret also use the area for foraging
and breeding during the spring and summer.
The
area was purchased with the help of $100,000 from CorLands,
the non-profit land acquisition affiliate of Openlands Project.
The Black-crown purchase is part of a planned acquisition
and restoration project that will eventually include 460
acres of wetlands and their associated uplands. The marsh
itself is part of a larger complex of wetlands that includes
Volo Bog Nature Preserve, Moraine Hills State Park, Stickney
Run Preserve and Singing Hills Forest Preserve. Together
they provide nesting, foraging, and roosting habitat to
over 100 species of migratory birds.

Insect
Heaven
Cressmoor
Prairie in Hobart, IN, a designated state nature preserve
owned and managed by the Shirley Heinze Environmental Fund,
has long been recognized as a site with outstanding biodiversity.
And insects are no exception. This fall, entomologist Jim
Bess will complete a two year survey of the 38-acre black-soil
prairie (one of only three sizable ones in the state). He
has recorded 370 insect species, including at least 21 that
were previously undocumented in Indiana, such as the sedge
leafhopper, switch grass leafhopper, and hop borer moth.
Fully 16 percent of the species are considered "remnant-dependent,"
meaning that they occur only on remnants of ancient natural
communities and are absent from the surrounding altered
landscape.
In
the past, says Bess, these prairies were shaped and maintained
by wildfires burning in a mosaic pattern, leaving unburned
areas to act as refuges. "Many remnant-dependent insects
overwinter as eggs, larvae, or adults in dead vegetation,
making them vulnerable to fire," says Bess. "For
these insects to survive, we must burn to keep the prairie
healthy, and we need to do it in a way that leaves patches
of unburned refuges from which recently burned habitat can
be recolonized."
Already,
Bess has confirmed that some species have begun reestablishing
themselves in previously burned areas. "This study
supports the common practice, used by burn management programs
across the region, of not burning entire sites all at once,"
says Indiana Department of Natural Resources regional ecologist
Tom Post.

Jet-Setting
"We
went for a three hour hike and saw all types of woodlands
and other habitats. We also saw frogs and raccoons. We even
heard woodpeckers," said an enthusiastic Junior Earth
Team (JET) member about camping at the Indiana Dunes State
Park this past May. JET is a collaborative youth program
launched three years ago by Chicago Wilderness partners
US Fish & Wildlife Service, the Chicago Park District, and
the Field Museum.
"For a lot of urban youth, the environment isn't something
they think of right away," said Nancy Saulsbury, Outdoor
and Environmental Education Manager with the Chicago Park
District. "The JET program is designed to change that
by exposing them to a variety of environmental activities
and professional opportunities." This year, 75 JET
members had the chance to hike and camp; conduct natural
resource surveys in Chicago parks; learn about local, regional,
national, and international environmental issues; teach
environmental concepts to younger campers; and represent
the Chicago Park District at environmental events across
the country.
The
program is year-round, but during six weeks of the summer,
eligible JET participants are employed in their local parks
as paid interns through the Mayor's Office of Workforce
Development. "Our goal is to offer teens both environmental
knowledge and job skills," said Saulsbury. "And
so, as the teens gain more experience, the JET program seeks
opportunities for them to learn from and work with other
Chicago Wilderness organizations."
Kudos
To McHenry County
The McHenry County Conservation District (MCCD) recently
finalized the purchase of more than 700 acres of land
237-acre Rose parcel (northwest side of Marengo), 78-acre
Wigginton parcel (Prairie Grove), 37-acre Boger parcel (Bull
Valley), 220-acre Lusky parcel (adjacent to Crystal Lake),
and 165-acre Napier South parcel (west side of Marengo).
The
Napier and Rose parcels connect to existing land holdings
along the Kishwaukee River, which has been identified by
the Illinois Department of Natural Resources as one of the
top three river systems in the state. The Wigginton parcel
has the only geological esker found in the county, according
to the MCCD Executive Director Craig Hubert. The MCCD plans
prairie restoration at the Rose and Lusky parcels and needs
site stewards. Call (815) 678-4431 if you are interested.

New
Members
On July 13, Chicago Wilderness welcomed four new members.
A coalition of ten bird clubs, the Bird Conservation Network
promotes the conservation of bird habitat in the Chicago
region. Ducks Unlimited seeks to protect, enhance, restore,
and manage wetlands and uplands needed by North American
waterfowl. The Fox Valley
Land Foundation works for the protection, management,
and restoration of natural areas, especially the Fox Valley
of northeastern Illinois. The Northwestern Indiana Regional
Planning Commission is a metropolitan planning organization
offering a forum for elected officials and other decision-makers
to develop and implement solutions in northwestern Indiana.
Orchid
Bonanza
This year, the captivating and federally-threatened eastern
prairie white-fringed orchid bloomed at 13 Orchid Recovery
Project sites, spread across Cook, DuPage, Grundy, Henry,
Iroquois, Lake, Kane, McHenry, Ogle, and Will Counties.
According to project coordinator June Keibler, it was an
average year with two astounding exceptions. "The
orchids at two sites just went bonkers. Both of them had
over twice as many orchids as they had ever had in the past."
Both sites are only about five acres in size, yet one sported
152 blooming plants, and the other had 270, compared to
the five and one respectively in 1991.
Although
the other sites did not show the same dramatic numbers this
year, Keibler says all have shown increases since the project
began. "The only downside is that more awareness of
this rare flower increases potential for plant poaching.
This has always been a problem for native orchids; that
is why we do not release information about their locations,"
says Keibler. The Orchid Recovery Project is a program supported
by the US Fish and Wildlife Service. For more information,
contact June Keibler at (847) 428-5594

Dirt
Marianne Hahn often drives by Witt Voet & Company's excavated
soil piles in Lansing, IL. When Hahn, a board member of
Thorn Creek Audubon Society, saw holes in one of the piles,
she realized a colony of bank swallows was nesting there.
Knowing these birds are protected by the 1996 Migratory
Bird Treaty Act, Hahn called the US Fish and Wildlife Service's
Division of Law Enforcement. In one call, Hahn reached right
person, special agent Joseph E. Budzyn.
"We
see situations like this more and more with all the development
going on in the region," said Budzyn. "We talk
to the property owners and find out what their intentions
are. In this case, Mr. Witt Voet was very receptive."
While habitat itself is not protected under the Migratory
Bird Treaty Act, property owners must obtain a permit to
move protected birds or active nests. (If the swallows had
been endangered species, the habitat too would have been
protected.) "It probably wasn't easy to work around
that pile of dirt, but the swallows weren't disturbed, and
there was plenty of time to raise their young. It was very
gratifying," said Hahn.

report a concern or ask about wildlife law, call the US
Fish and Wildlife Service at (847) 298-3250.

Exploding
Rockets
It's been a bumper year for Cakile edentula, also
known as sea rocket, a state-threatened coastal plant in
Illinois. Said local birder and activist Leslie Borns, "Every
summer we've noticed a few at Montrose beach, but for some
reason this year there's an explosion of this plant! Could
be all the rain we had last spring and early summer."
Back in 1993, nobody thought sea rockets or any Great
Lakes coastal plants still survived at Montrose.
But one September morning that year, botanist Margo Milde
was birding there when she recognized the purple flowers,
succulent leaves, and swollen seed pods of sea rockets.
"It
was very exciting to find it in such an urbanized area.
Sea rocket is a very conservative plant, meaning it's usually
first to disappear when its habitat is altered," says
Milde. Yet the sea rockets seem to be surviving and even
flourishing in the heart of the city. Borns notes that during
an August Bird Conservation Network/Openlands tour, masses
of it were also discovered behind the South Shore Cultural
Center at 71st St. and the lakefront, on a site many are
seeking to preserve as a natural area.
Streams
Tons Cleaner
More than 650 volunteers removed approximately 10 tons of
trash from DuPage County streams at the Conservation Foundation's
River Sweep '99 on June 5th. It was a record number of volunteers
for the nine year old program. Since 1991, this annual event
has involved more than 3,000 volunteers who have removed
an estimated 118 tons of garbage.
