MONITORING

Numerous federal, state, tribal and academic institutions are actively monitoring for zebra and quagga mussels (i.e., invasive mussels) and other nonnative species in a variety of ways. The information and maps contained within this site are intended to provide an up to date synopsis of who is monitoring for what species, where, how and when. This information can help managers and researchers to determine if the current level of monitoring is sufficient, or whether efforts should be redirected to better fulfill various needs.
