Table 1. Summary of quadrat, removal, and distance surveys performed in three Central Minnesota lakes surveyed during the summer of 2018.
We report the total area surveyed, the number of detected clusters, and the total time taken to complete all the transects in each survey. CV denotes the coefficient of variation in the estimated density.
