Wildlife biologists and highway engineers from 14 western states convened January 29 – 31 in Salt Lake City, Utah to evaluate what is known about conflicts between ungulates and highways and how wildlife and transportation agencies can collaborate to improve highway safety and conservation. They were joined by experts from five federal agencies, three universities, and over a dozen NGOs. The workshop revealed the importance of a shared vision among top-level leaders in wildlife and transportation agencies as well as solid relationships between field-level staff, local stakeholders, and NGOs. Other outcomes included recognition of the need for earlier integration of data on ungulate movements in highway planning processes; additional research into the design, effectiveness, and cost:benefit ratios of crossing structures; and more creative approaches to financing and implementing permeability of transportation corridors. Theodore Roosevelt Conservation Partnership (TRCP) chief scientist, Ed Arnett, helped organize the workshop and was pleased to see the level of commitment by both wildlife and transportation interests to work together to solve problems.
