Ecology and Management of Invasive Species and Forest Ecosystems

Invasive Species

The northeastern and midwestern regions of the United States have the largest concentrations of invasive forest insects and pathogens in the country. These pests affect ecological and socio-economic resources in our nation’s wildlands and urban forests, with costs estimated at more than $138 billion/year. Invasive species are second only to habitat destruction as a cause of species declines and conservation issues. Global trade continues to increase and with it the rate of invasive species introductions and consequent costs of efforts to prevent and manage invasive species.
