Invasive Invertebrates
Invasive Invertebrates
An invasive species is an introduced species that has established itself and causes negative impacts to the native environment, the economy, and even human health. WARC science is used by resource managers to help mitigate and control these problematic species, including the giant apple snail.

Asian Tiger Shrimp Distribution and Genetics
The Asian tiger shrimp began appearing in commercial shrimp catches in 2006. They grow larger than native shrimp and are known to be fierce predators - so shrimpers and managers are concerned about the potential effects this species might have.
Future Aquatic Invaders of the Northeast U.S.: How Climate Change, Human Vectors, and Natural History Could Bring Southern and Western Species North
Researchers will evaluate the potential of aquatic species to invade the Northeast U.S. Following the identification of appropriate target species by regional stakeholders, researchers will gather data from the NAS database and develop models to determine habitat suitability for each species.
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
