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.
Using Anna’s hummingbird as a case study, the researchers propose to develop a genetic toolkit to assess how Caltrans construction projects impact bird populations.
This project uses time lapse cameras to monitor sea-level rise in both California and Georgia. Results could inform adaptational infrastructure planning as sea-level rise continues.
The research team will statistically model the effect of traffic noise and light from traffic on occurrence of mountain lions, mule deer, and Peninsular bighorn sheep and movements of GPS-collared individuals as they approach highways.
The researchers will develop a method for statewide modeling of noise and light intrusion into areas adjacent to roads to aid locating and designing crossings to maximize wildlife approach and use.
This policy brief presents results from a study that measured wildlife reactions to traffic noise and light near California highway crossing structures.
This project studies how sensitive species react to traffic noise and light. The researchers then apply this information to the effectiveness of wildlife crossing structures.
