Biological Resource -- A colorful new resource, Midwestern Wetland Flora is a field guide for both novices and experts and contains 300 species of wetland plants. An Identification Key is given to help identify unknown plants and a very useful Illustrated Glossary is presented. Each plant contains at least one color photo, a line drawing, and textual information about habitats, flowering dates, and distinguishing marks. Distribution maps are in preparation and will be provided in the near future.

Biological Resource -- Human Disturbances to Waterfowl -- This bibliography contains excerpts or annotations from 211 articles that contain information about the effects of human disturbances on waterfowl. It is browseable by author, species, subject, and geography.
