WeekendProject: Invasive Species Coloring Sheets!
FRIDAY NOV 12 2010

Parents, if you're looking for a science activity for the kids this weekend, try downloading our new wildlife coloring sheets explaining the invasive and native species of California!

These USGS Education Handouts were originally developed for the San Diego Zoo's "Reptilemania" event back in September. Hundreds of curious young minds stopped by the USGS booth that weekend to learn about the reptiles and amphibians that live in Southern California.

The two native species featured are being studied by WERC in collaboration with the San Diego Zoo. WERC scientist Adam Backlin is monitoring mountain yellow-legged frogs in the wild, while zoo researchers are breeding the species in captivity. WERC scientist Chris Brown is doing the same for the western pond turtle.

And while the kids are coloring away, you too can learn more about these animals in our Field Guide to the Reptiles and Amphibians of Southern California, online at

Happy coloring!
