Multi-Species Benefits

The State Highway System currently offers some opportunities for species migration in providing access to habitat for common and listed species. However, there are many opportunities to improve the use of existing under-crossings and to determine where additional multi-species connectivity opportunities are needed.


The multi-species connectivity story map below demonstrates where species are currently crossing, attempting to cross but not actually crossing, or where there may be needs to further consider science and data in determining where to provide new crossing opportunities.



Watershed corridors connect aquatic and terrestrial species populations throughout California. Connectivity corridors provide safe passage to high-quality habitat for threatened, endangered, and special status species, enabling resiliency for individuals and populations that have been decimated by drought, wildfires, climate change, urban development, roads, dams, agriculture, and other impacts.
