Oaks in Southern California are under incredible stress and oak woodlands are a threatened and declining plant community. Southern California hosts a variety of oak trees including the rare Engelmann oak, (Quercus engelmanii). Suburban and ex-urban development threaten these plant communities as fragmentation is increasing in natural areas.
Furthermore, the long-term drought from 2012 to 2016 caused a decline in the production of seedlings in the oak woodland community. All in all, oak canopies in Southern California are declining. Until these pests are successfully controlled, the best method we have to prevent dramatic losses in oak woodlands are to widely plant acorns and seedlings.
Oaks are a meaningful and important part of tribal culture and are a crucial component of woodlands in Southern California. UCCE is committed to working with indigenous communities to assist in preserving, restoring and protecting our shared natural resources.
