Target Species

Target species are potential County Records - species not yet documented in the county. 'Local Obs' is Local Observations and indicates the number of times that the species has been observed in adjacent counties since 2000, and '# of Counties' is the number of adjacent counties in which those recent observations took place. Zero local observations or recent counties means the existing records are historical. 'Peak Active' is a relative description of when the species has been known to fly.

Sandusky County lies within the Maumee Lake Plains area of the Huron-Erie Lake Plains ecoregion, which was the location of the now mostly-drained and channelized Black Swamp. Located on Lake Erie, the Sandusky River flows north through the county into Sandusky Bay which forms the NE border of the county (see Sandusky River and Sandusky Bay Tributaries Watersheds). The county is entirely within the Lake Erie Watershed (See p. 11 in Ohio Coastal Atlas: Chapter 2 for a detailed watershed map).
