Over the two evenings of the August bat walks, the Echometer sensors gave plenty of indications of the presence of bats, even if we can't absolutely rely on the exact IDs. The sensors suggested the possible presence of six of Wisconsin's eight species: Little Brown, Big Brown, Hoary, Silver-haired, Tricolored, and Eastern Red.

We had more than 40 enthusiastic volunteers this year to survey 24 Dane County sites for aquatic invasive species.
