Forest Health Issues
A. Exotic or novel pest introduction/
outbreak, i.e. Sudden Oak Death,
Emerald Ash Borer, Asian Longhorned
Beetle.
3.
B. Ongoing efforts with major pests, i.e.
Gypsy Moth and other established exotic
and native pests, oak wilt etc.
Off-plot Survey Results
A. Mortality and defoliation maps.
Fourth year of outbreak
Forest tent caterpillar 7.4 million acres defoliated.
Forty ninth consecutive year
of detectable defoliation.
Spruce budworm 91,000 acres
defoliated.
