Hundreds of species from other countries arrive in the United States unintentionally each year - and introductions are on the rise. America is under siege by many harmful species of plants, animals, and diseases, primarily from other countries. The current environmental, economic, and health-related costs of invasive species (also called alien, exotic, nonindigenous, or non-native species)could exceed $138 billion per year - more than all other natural disasters combined. Invasive species, in short, are the number one environmental challenge of the twenty-first century.
The Invasive Species Information Node provides access through a single Web portal to a vast array of information on potentially harmful invasive species throughout the nation. This increased accessibility of data from all reliable sources allows different information types to be combined and compared, which permits improved management of invasive species and better identification of vulnerable habitats.
