NEW PUBLICATION: Idaho Barn Owl Study Explores High Rates of Road Mortality

Ibis, an international journal of avian science, has published an article based on a WTI Road Ecology project in Idaho.  “Spatial, road geometric and biotic factors associated with Barn Owl mortality along an interstate highway” studied the high rates of collisions between Barn Owls and vehicles on Interstate 84 in Southern Idaho.  It stems from a WTI project on potential mitigation options for reducing vehicle collisions with barn owls, which was a collaborative research effort among WTI, Boise State University, Murdock Charitable Trust, Federal Highway Administration, Idaho Transportation Department and Idaho EPSCoR.  Angela Kociolek served as the Principal Investigator.

New Report: National Key Deer Refuge – Strategies for Reducing Wildlife Vehicle Collisions

WTI has released a new report investigating Key Deer mortality along a segment of Highway 1 within the National Key Deer Refuge in Florida. Road Ecologists Marcel Huijser and James Begley found that 75% of all reported mortalities in this area were related to collisions with vehicles.  The team also investigated and mapped how the locations of collision “hotspots” have changed since the installation of wildlife fencing, underpasses, and deer guards. The final report (“Exploration of opportunities to reduce Key Deer Mortality along US Highway 1 and other roads, National Key Deer Refuge, Florida, USA”) summarizes the pros and cons of eight different strategies aimed at reducing collisions with Key Deer on Highway 1.

The National Key Deer Refuge final report is now available on the WTI website.  This research effort is part of a technical support contract for National Wildlife Refuges, which encompasses projects at refuges across the country.
