Invasive Species are harmful non-native species that can cause serious damage to our environment and economy. Once introduced and established, these species are difficult and costly to eradicate or control. As a result, preventing their arrival is the most effective approach for reducing the harm they pose. NECIS strives to prevent the introduction and spread of harmful invasive species in the United States in order to sustain our native species and ecosystems, and to protect the U.S. economy.
