Invasive Species 101
Invasive species are a harmful subset of non-native or introduced species, that adversely affect native plants and animals and upset the balance of ecosystems. Increasing globalization of our economy, with its extensive travel and shipment of goods, brings an ever-increasing number of new invasions. In the United States alone, scientists estimate that about 7,000 invasive species of plants, mammals, birds, amphibians, reptiles, fish, arthropods, and mollusks are established and costing local, state, and the federal government billions of dollars each year.
Our experts strive to substantially reduce the introduction and spread of harmful invasive species in the United States and to decrease their impacts on native ecosystems and biodiversity. Specifically, we are working together with colleagues in the scientific community on effective approaches to block major pathways of invasive introductions through better screening of intentionally imported species (e.g., through pet and nursery trades) and improved inspections for unintentional introductions (e.g., in packing materials, wooden crates, and shipping ballast water).
