Recovery & Restoration

Oak Woodland Saplings
Why Recovery?

GSOB infestations have killed at least thousands of oaks in Southern California, damaging habitat for many important species, reducing cultural resources and natural beauty, and depriving California of an iconic landscape feature. To minimize these losses in Southern California, we must actively work to restore oak populations and assist landscapes to recover.

Oak Woodland Recovery

The impacts of GSOB, along with human impacts, fire and drought, and diseases have been profoundly detrimental to oak woodlands in San Diego County. Tree mortality is at a higher rate than oak woodlands can naturally sustain. This page details the methods and factors to consider when working to restore oak woodlands.

Restoration Projects

Read about some of the steps UCANR, partner agencies, and local communities are taking to help restore oak woodlands in Southern California. Restoration activities have been occurring in the San Diego region since 2008, and as the GSOB infestation spreads and oaks are damaged or killed, restoration work will continue to be necessary.
