The University of California Cooperative Extension offices are the bridge between local issues and the power of UC research.

The Urban Forestry program aims to prevent pest problems and control current infestations in Southern California. We are based in Orange and Los Angeles counties and we also collaborate with other counties in an effort to stop the spread of these dangerous pests to new uninfested areas.

We provide guidance to public and private entities on how to implement integrated pest management programs to deal with tree pests. We work together with landscape managers to find solutions that minimize the use of pesticides while providing effective management.
