5.0 Monitoring methods for forests vulnerable to non-native invasive pest species

Abstract

Non-native invasive species pose a serious threat to forest resources, requiring programs to monitor their spatial spread and the damage they inflict on forest ecosystems. Invasive species research in the Delaware River Basin (DRB) had three primary objectives: to develop and evaluate monitoring protocols for selected pests and resulting ecosystem damage at the IMRAs that can be cost-effectively implemented as part of extensive monitoring programs, to test a collaborative monitoring strategy for assembling pertinent information to track pest movement and mitigate the effects of pest infestation in the DRB, and to develop maps of forest condition in the DRB that depict areas most vulnerable to specific pests.
