Maryland Darter
Saw a post earlier on about the Maryland Darter elsewhere, it is the only endemic vertebrate to Maryland, and was last seen in 1988 in Deer Creek.
It's been nearly 40 years since the last confirmed sighting, but that sighting was already part of a much smaller series of sightings from the 60s to 80s of the species, before then having not been seen since 1912; it camouflages well into the environment.
Does anyone know of any programs for it/attempts to rediscover it?
I've tried reaching out to Friends of Harford, Harford Land Trust, and the Susquehanna Wildlife Society, but so far only Harford Land Trust has replied, and they don't have any active conservation efforts for the species.
