Abstract Detail


Kurtz, Cassandra [1], Hansen, Mark [1].

What have we learned from nearly a decade of invasive plant data covering the Central and Northeastern United States?

Invasive plants are a global concern due to their competitive nature and widespread impacts. These plants annually cost billions of dollars to monitor and control. The Forest Inventory and Analysis crew of the USDA Forest Service Northern Research Station (NRS) has monitored forested plots for invasive plants across the 24 states of the Midwest and Northeast since 2007. During this time frame sampling intensity has changed from 20 percent of Phase 2 inventory plots (2007-2011) to 12.5 percent of inventory plots (2012 to present). On these plots the presence and cover of 40 invasive plant species (39 species and one undifferentiated genus [nonnative bush honeysuckle]) are monitored. These data are collected in addition to the standard tree (e.g., species, diameter, height) and site (e.g., road distance, physiography) variables. Currently over half of the forested plots in the NRS region have one or more of the monitored invasive plants present. We have also found that IPS tend to occur on plots that are less forested, have a lower basal area, and are closer to roads. Additionally we are noting an increase and spread of many of the invasive plants in this region.
