Illinois Parks & Recreation May/June 1994 • Volume 25, Number 3 Toothpicks Bring Help to
Rare Forest Preserve Orchids by Sarah Surroz
Russ Dombeck's orchids were running out of
time. With only a few days left before the end of
their blooming season, there was still no sign of a hawk moth coming to their rescue. Once again,
the rare flowers were going to wilt without a visit
from their sole pollinator. No fertilization would
occur and no seeds would form. With a prairie
sun hot on his back and a persistent mosquito at
his neck, Russ readied his toothpick and moved
in. If the hawk moths couldn't do this job, then he
would have to do it for them.
Russ' prairie white-fringed orchids actually
grow in a Lake County Forest Preserve. It's just
that after 20 years of watching over this patch of
rare plants, this volunteer plant monitor has understandably become somewhat attached. He's not
alone. Volunteers and staff from a number of national, state and local agencies stepped up their
efforts last year to join together and save this orchid from the human actions that brought it to such
dire straits.
Threatened on a national level and endangered
in Illinois, the prairie white-fringed orchid is sliding toward extinction at a steady pace.
Once plentiful over the prairies of northeastern North
America, the orchid took its biggest hit when farm
plows tore up most of its habitat. Urban development, wetland drainage and the loss of wildfires
socked it again.
The species' last stronghold is Lake County,which supports eight of the world's 55 remaining
populations. In the Forest Preserves, they are getting a boost from our land managers,
who are clearing non-native plants that threaten to overtake them
and who are safely returning the natural benefits
of fire to the land. A recent $3,500 grant from the
Illinois Department of Conservation has boosted
their efforts.
But the plants still have their challenges, including people who feel it is their right to steal
orchids for backyard gardens. These felony transplants almost always fail. You see, the
white-fringed orchid is a delicate plant with very exacting needs. Even research botanists have a hard
time growing them out of the wild. Not only do
sunlight and moisture need to be just right, a certain soil fungus must be present or the roots falter.
As if that's not bad enough, there's the hawk
moth problem. Out of all the bugs and birds and
bats and other pollinators out there, this orchid has
evolved to rely on just that one species for seed
production. It's the only critter out there with a
tongue long enough to do the job.
No one really knows much about the hawk
moth or its numbers. June Keibler, national Project
Coordinator for the orchid's recovery, hopes for
more research on the insect soon. Meanwhile, with
funding from the U.S. Fish and Wildlife Service
and direction from a National Recovery Plan, she
started working with The Nature Conservancy to
coordinate some surrogates.
Last year, 25 volunteers spread across the
Chicago area for the 1 1/2 weeks that the orchid
blooms. Eight headed for the Lake County Forest

Preserves. Russ Dombeck was one of them.
Russ worked steadily in the summer heat, his
toothpick serving as a hawk moth tongue. A
Libertyville chemist, he enjoyed the solitude of
this prairie he'd been volunteering at for years.
Since he'd tagged all of the plants and mapped
the eight-acre site to an inch-scale, he knew exactly where each of his charges were. Within three
hours, he completed his job, fertilizing the six to
25 blossoms on each of two dozen plants.
In the coming weeks, he and his colleagues
were thrilled to see the results. Seeds no larger
than a grain of sand matured and dispersed. Some
were gathered and taken to other sites, offering a
genetic shot in the arm to small populations. All
sowed hopes for a new generation and a future
recovery of this very special plant.
