Aquatic Invasive Species Monitoring



Aquatic invasive species (AIS) monitoring involves searching the lake for aquatic invasive species like Eurasian watermilfoil, zebra mussels, rusty crayfish, and others. The frequency that volunteers perform AIS monitoring varies, but most volunteers do this a few times per year. Most volunteers conduct AIS monitoring in high-risk sites around their lakes (like boat landings) to detect early populations of AIS. Early detection of AIS is crucial for effective, inexpensive management, so these volunteers are incredibly valuable.
