Join us for the tenth biennial ICOET conference hosted by the California Department of Transportation (Caltrans) and California Department of Fish and Wildlife, with support from the US DOT Federal Highway Administration.
This project initiates a general framework for assessing population-specific impacts of Caltrans projects on avian populations with the future goal of providing specific tools to avoid impacts with hummingbirds nesting on or around bridges.
To better understand the dynamic between wildlife and vehicle traffic in Northern California, a study examined whether State Route 49 acts as a barrier to movements of two similar species with different tolerances to human activity. This policy brief summarizes findings from that study and discusses the policy implications.
The goal of this project was to create a genetic toolkit for identifying breeding bird populations and assigning individuals to those populations. Ultimately, such tools could be used to assess population-level impacts when there are conflicts with birds at infrastructure construction sites.
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.
