Our native oak trees along the American River Parkway are facing a growing threat from the Mediterranean Oak Borer (MOB), an invasive beetle responsible for serious tree damage, dieback and mortality.
Now, you can help fight back!
Sacramento County Regional Parks is inviting community members to become community science detectives and help track the spread of MOB along the Parkway. No forestry or entomology experience is necessary! Local experts will provide hands-on training at the beginning of each session.
Participants will learn how to identify signs of potential infestation, inspect native oak trees and map their findings using mobile technology. Every set of eyes helps us better understand the threat and protect our local oak canopy.
