Roadkill Reports of Coyotes, by Fraser Shilling

Since 2009 hundreds of volunteer observers with the California Roadkill Observation System (CROS,http://wildlifecrossing.net/california) have reported almost 31,000 roadkilled animals on our roads and highways, representing 400 species of reptiles, amphibians, birds, and mammals. Their effort has made CROS the largest system like it in the world. For certain mobile and easily recognized species, like coyotes, we can map occurrences of dead animals and start to figure out where they are getting hit most often and possibly why.

The map of roadkill coyote [to the left] is for 134 reported coyote carcasses, out of 723 reported for the whole state between 9/2009 and 4/2015. The # reported does not represent ALL occasions when coyotes were killed by cars, just a sample. Although we can’t say for sure yet, it looks like highways 101, 280, 680/84, 80, and 37 have stretches where more coyotes are hit. Please join the hundreds of CROS volunteers monitoring our roads and highways for roadkill to help protect drivers and wildlife from colliding. Feel free to contact CROS lead Fraser Shilling, just internet search him for his contact info.
