Research

BSAP collaborates with the Illinois Department of Transportation to conduct applied research that links ecological science with transportation planning and design. Our studies address real-world challenges related to habitat connectivity, species conservation, and environmental compliance.

Some Research Projects

Deer stands next to road as light snow falling, dried grass and trees in the distance.

Understanding Wildlife–Vehicle Collisions in Illinois

BSAP analyzed the factors contributing to wildlife-vehicle collisions in Illinois and evaluated mitigation strategies such as fencing, crossings, and driver awareness measures. The review identifies high-risk areas and recommends integrating wildlife conservation and safety considerations into transportation planning and infrastructure design.

Aquatic Organism Passage at Highway Crossings: An Implementation Guide

BSAP developed design guidance to improve stream connectivity at bridges and culverts. The guide outlines flexible, science-based approaches for removing barriers to fish and wildlife movement while maintaining transportation performance.

Planning for Encounters with Special Management Areas

BSAP collaborated with IDOT to identify and characterize thousands of conservation-relevant areas located along or near Illinois roadways. The project assessed how these special management areas are currently maintained and developed best-practice recommendations to help guide consistent, proactive management of sensitive habitats across the state.

Rusty Patched Bumble Bee Best Management Practices

BSAP researchers developed best management practices for the Federally Endangered Rusty Patched Bumble Bees during IDOT construction and maintenance activities. The guidance outlined proactive avoidance and mitigation measures to streamline project coordination with resource agencies and support environmental compliance.

Carex of Illinois and Surrounding States

With support from IDOT, BSAP botanists authored this comprehensive field guide to the oval sedges. The book provides identification tools, distribution maps, and natural history information for twenty-five Illinois species and related taxa across neighboring states. Drawing on thousands of specimens, this work supports conservation, restoration, and ecological research throughout the Midwest.
