This TRB webinar will cover important steps in defining and setting goals, identifying methods that work, and monitoring continuing impacts in ecologically-sustainable transportation
This research brief summarizes findings and implications from the project where researchers at UC Davis sequenced entire genomes for 40 individual Anna’s hummingbirds (Calypte anna) from across California to identify breeding populations and develop a genetic toolkit to assign individuals to those populations. The presence of this species at bridge construction sites has resulted in construction delays in part because little information exists on the status of different populations within the species.
Transportation systems cause negative changes in adjacent and distant ecosystems’ characteristics and processes. These changes are usually not mitigated during construction, maintenance and "re-construction" of facilities.
Traffic impacts on wildlife behavior are largely unknown, but may be the primary determinant of wildlife distribution in response to fragmentation from roads. This webinar will present findings from 3 years of research by the Road Ecology Center at the University of California, Davis on the distribution of wildlife relative to highways and their behavior in response to instantaneous traffic disturbance.
The Wildlife Crossing Calculator (WCC) includes a set of analytical tools to help estimate the costs to the public of crashes involving wildlife and compare those costs with the costs and benefits of wildlife crossing mitigations.
