MISSION  CREEK
AMPHIBIAN

The habitat for reptiles and amphibians along the Mission Creek Stream Corridor has been disturbed by humans over the last 200 years.  Today this area is not as desirable a habitat for reptiles and amphibians.  Hopefully as the Mission Creek provides a more native riparian vegetation the reptiles and amphibians will return.
