Wetland Restoration along the Illinois
River
Wetland Ecosystems were a vital part of the Illinois
River Valley centuries ago.Their
inherent value cannot be calculated given the tremendous amount of plant
and animal life they support.It
is estimated that 46% of all threatened and endangered species in the United
States are associated with wetland habitats. (1) Wetlands are valuable
for their habitat, which produces massive numbers of plant and animal life
as well as their role in reducing floods and improving water quality.One
type of habitat associated with wetlands is a community of moist soil plants.These
plants, which include a variety of grasses, sedges and forbs,are
highly productive and serve as shelter, protection from predators and food
sources for a variety of animals.The
Illinois River Valley floodplains contained thousands of moist soil plant
communities, which in turn supported millions of waterfowl, and other animals.Although
moist soil plants are adapted to a moist environment and can withstand
periodic flooding, current regulatory practices on the Illinois River and
elsewhere are reducing these wetland communities to mudflats.In
addition, much of the Illinois River Floodplain has been leveed for agriculture,
reducing the size of these communities to a fraction of their former glory.Numbers
of animals relying on moist soil plant communities have likewise decreased
tremendously over the past 100 years.Understanding
and restoring moist soil plant communities is the first step in reviving
the vital floodplains ecosystem that existed along the Illinois River.The
Illinois Nature Conservancy has purchased two sites along the Illinois
River which will be restored to wetland habitat, Emiquon (near Havanna,
IL) and Spunky Bottoms (near Meredosia, IL)A
total of 11,000 acreswill be restored
to native habitat.Restoration Plans
call for backwater lakes with associated moist soil plant communities,
a swamp forest,and short and tall
grass prairies.
This paper will address plant characteristics, important
plant species and ecosystem requirements of moist soil plants proposed
for Emiquon and Spunky Bottoms.
