What We Do

Our conservation vision is to provide enduring resource benefits through strategic conservation actions that support a growing conservation estate and a more resilient landscape throughout Illinois, Iowa and the greater Midwest. If you require a review of your project with a federal nexus (funding or permitting) for impacts to federally listed species or critical habitat, please see our project review page for more information.

Our Species

We conserve and restore threatened and endangered species and their habitats with a focus on imperiled bat and freshwater mussel species. Our office has also been actively involved with the conservation and recovery efforts for species such as the Topeka shiner, Iowa Pleistocene snail, decurrent false aster, and eastern prairie fringed orchid to mention a few. In addition, our office has taken an active role in the conservation of pollinator species including the monarch butterfly and their habitats in Illinois and Iowa.

The decurrent false aster is threatened species. It is a perrenial plant found in moist, sandy floodplains and prairie wetlands along the Illinois River. Although not very tolerant to prolonged flooding, this plant relies on periodic flooding to scour away other plants that compete for the same...

Cluster of roosting bats.

The Indiana bat is a medium-sized Myotis, closely resembling the little brown bat (Myotis lucifugus) but differing in coloration. Its fur is a dull grayish chestnut rather than bronze, with the basal portion of the hairs on the back a dull-lead color. This bat's underparts are pinkish to...

Projects and Research

Get Involved

We frequently partner with schools, museums, industry, private individuals and conservation organizations to communicate our involvement with fish and wildlife resources and conservation opportunities within the states of Illinois and Iowa. We also work with these groups and individuals to develop or identify conservation projects that may benefit threatened and endangered and other important fish and wildlife species and their habitats.
