Abstract

The hemlock woolly adelgid (HWA), Adelges tsugae, is a small aphid-like insect that feeds on the xylem ray parenchyma cells near the base of hemlock needles. This insect, a native of Asia and western North America, was first noted in eastern North America in 1951 and has now spread to infest hemlock in at least 17 states. The increased hemlock mortality driven by this insect requires land-managers and silviculturalists to develop stand management plans that account for the potential impact this invasive species. The Forest Vegetation Simulator (FVS) was developed to simulate stand development through time under a variety of landmanagement actions and has the flexibility to include impacts by fire, pathogens, insects, and other disturbances. Using available data that describe the timing, intensity, and trajectory of infestations, we have developed two simple event monitor addfiles (*.kcp files) for the northeastern and southeastern FVS variants.
