Welcome to our site where registered users can conduct automated hotspot analysis on state highways using data that they supply. We also offer a Real-time California Deer Incidents and Wildlife Vehicle Conflict (WVC) Hotspots Map, which pulls in records from various sources, including the California Roadkill Observation System (CROS).

About the Road Ecology Center

The UC Davis Road Ecology Center brings together researchers and policy makers from ecology and transportation to design sustainable transportation systems based on an understanding of the impact of roads on natural landscapes and human communities. Browse this website to learn more about the Center and the emerging science of Road Ecology.


We would like to thank all those who helped make this website and service possible. Thanks to the Pacific Southwest Region UTC for providing support for development of the website. Thanks to Transportation and Fish and Wildlife staff from Colorado, Idaho, Maine, Minnesota, Nevada, and Virginia for helping to develop and beta-test the analysis system.

This website is built with Open Source Software (various licenses), and while we can't possibly thank everyone who contributed to all the various software packages need for this project, we would like to highlight a few. The website framework is Drupal 8, which manages the content (hotspot analyses) users generate when they log into the site; The statistical modelings (again hotspot analyses) is done with R, a robust set of statistical libraries which you've likely already heard about; the mapping was done with a set of Javascript libraries on the front and, and Geoserver on the back end. The front end libraries include Leaflet, Leaflet Group Layer Control, Leaflet Icon Layers Control, and the ClusterMarker Manager.
