Specimen IDDateSpeciesNew AreaAlert Risk Map Explanation of ARM
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM), was developed to characterize the waterbodies at potential risk of invasion from a new nonindigenous species sighting. The ARM tool is a short-term risk assessment utilizing a nonindigenous species' current extents and development of credible scenarios of its potential movement within a drainage based on its mobility and drainage barriers (dams). Maps from ARM will indicate lakes, river reaches, and other waterbodies that are at potential risk of invasion from a new nonindigenous species sighting and will accompany the NAS Alert emails sent out to subscribers and managers.
