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.

Located along the eastern shore of Lake Erie, the Portage Escarpment parallels the lake shore, dividing Lake County between two ecoregions. The section along the lake is within the Erie Lake Plain region, and the southern part of the county is in the northern edge of the Glaciated Allegheny Plateau. The Grand River enters the county in the east, flowing westward along the escarpment and making a 90 degree turn to the north, zigzagging towards the lake. The county is entirely within the Lake Erie Watershed (See p. 12 in Ohio Coastal Atlas: Chapter 2 for a detailed watershed map).
