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 |
