Pests & Other Problems
Why is it important to keep our trees and green spaces healthy?
- Trees and green spaces provide essential ecosystem and economic benefits such as energy cost savings, storm water absorption, and carbon sequestration.
- Dead trees, brush, and grass are a major fire risk in both urban and open spaces.
- Infected trees and plants threaten other nearby green assets and could devastate the ecological health in our region if left unmitigated.
- Minimizing infections and infestations at the beginning can help minimize long term costs for treatment and prevent spread.
- Pest, disease, and noxious weed pressure will likely persist as the effects of climate change worsen.
Current & Significant Pests:
Emerald Ash Borer
contact a certified arborist immediately and report EAB confirmation to firstname.lastname@example.org.
Symptoms of EAB may include:
- D-shaped exit holes on the surface of the bark, and S-shaped galleries underneath the outer bark.
Please contact a certified arborist to conduct an accurate tree assessment if you see symptoms of Ips bark beetles in your pine or spruce trees, and report Ips confirmation to email@example.com.
Symptoms of Ips may include:
- Yellowish- or reddish-brown dust accumulating in bark crevices or around the base of the tree
- Tree discoloration (“fade”); dieback at the top of the tree
- Woodpeckers feeding on the trunk or larger branches (they’re a common predator of the Ips beetle)
- Small round holes in the bark. You’ll usually see these after the beetles have already done their damage and exited the tree.
