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.| Common Name | Scientific Name | Ohio Obs | Local Obs | # of Counties | Peak Active |

The Berea Escarpment runs diagonally through Huron County from SW to NE, dividing the southern 2/3 of the county into two subregions of the Till Plains ecoregion. The north central part of the county is in the Lake Erie Plain ecoregion. The entire county is within the Lake Erie watershed, with the Huron River running south to north through the center of the county is entirely within the Lake Erie Watershed (see p. 11 in Ohio Coastal Atlas: Chapter 2 for a detailed watershed map).
