Aquatic Plant Research Point-Intercept Sampling Maps

DNR Science Services have developed a standardized methodology for sampling aquatic plants in lakes and flowages, and established a centralized system for creating grid maps, processing coordinate requests, and storing standard point-intercept grid maps and GPS coordinate files. To date, Science Services has provided maps and points for over 1292 lakes and flowages throughout WI. This work supports plant sampling by the DNR Bureau of Water Quality, counties, municipalities, Great Lakes Indian Fish and Wildlife Commission, consultants, universities and lake associations. Providing standardized point-intercept grids and methodology allows survey results to be comparable across different lakes, years, and surveyors, and allows managers and policy makers to easily understand and compare survey data. Wisconsin's peer-reviewed standardized methodology has been adopted by other states and regions.
