Guidance for Conducting Aquatic Invasive Species Early Detection and Baseline Monitoring in Lakes

This document was developed to provide a standardized set of procedures (protocol, field data sheet, and data inventory) to supplement DNR efforts in early detection and baseline monitoring of aquatic invasive species throughout various lakes in Minnesota. This monitoring protocol is for those with considerable experience searching for and identifying aquatic invasive species. Search methods include a lake-wide meander of the near-shore zone as well as wading, snorkeling, netting, and rake sampling in areas most vulnerable to aquatic invasive species. Data collected should be maintained by those conducting the monitoring and may be submitted to DNR AIS staff on an annual basis.
