Invasive species are plants, animals, or pathogens that are non-native (or alien) to an ecosystem and whose introduction causes or is likely to cause harm. Invasive species are considered the second greatest cause of biodiversity loss. Recognizing the threat that invasive species pose to native plants and animals, biodiversity, and ecosystem functioning, we highlight during National Invasive Species Awareness Week (February 21-27, 2016) the importance of having access to data and information on invasive species in order to identify and control their spread. Data.gov lists a variety of information and data resources on invasive species, including the U.S. Geological Survey’s (USGS) Nonindigenous Aquatic Species (NAS) information resource, which provides alerts, occurrences and factsheets of aquatic invasive species, the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service’s PLANTS Database, which provides lists of invasive plants in the U.S., and the USGS Biodiversity Information Serving our Nation (BISON), which provides occurrence records for most terrestrial and aquatic species that are considered invasive.
