Species invasions are fundamentally altering ecosystems around the world and changing our views on species saturation. Natural ecosystems seem increasingly to accommodate non-native species despite the abundance of native species. The authors examined county- and regional- scale information on native and non-native species richness to determine what makes some areas so susceptible to invasion.

The USGS serves the nation by providing reliable scientific information to: describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.
