Polyphagous Shot Hole Borer in OC Parks Trees
The Polyphagous Shot Hole Borer (PSHB) is an invasive beetle that attacks common native and landscape trees, leading to branch dieback and overall decline. This can have a devastating effect on local trees, and you may see some being treated or removed in County parks.
What OC Parks is doing about PSHB:
Actively mapping and monitoring the spread and severity of PSHB on park lands.
Supporting University of California PSHB research in County parks.
Participating in regional land manager groups focused on stopping PSHB infestations.
Developing PSHB management protocols with input and review by top University of California researchers.
Focusing on preserving trees.
Removing trees that can’t be saved.
Developing a reforestation plan that considers the drought and PSHB.
How you can help reduce the spread of PSHB:
Don’t transport firewood. “Buy it where you burn it.” For more information about responsible firewood handling, see http://firewood.ca.gov/
