I am about to propose a project involving signs along a river course and lakes where a threatened species of turtle lives; Pseudemys gorzugi.
Old signs exist there now, and have a surprising impact, (see picture), despite the fact that triploid grass carp have not been stocked there in over six years, and none exist now. Just last week I talked to a fisherman that thought that common carp should not be removed, because of the old signs... wrong species.
Clearly the signs have impact. Currently, the species of turtles suffer human persecution from fisherman who perceive the turtles to be a competitor, to casual firearms shooters looking for random targets.
My project needs to educate the public in a positive light. It must also be brief. In the city of Carlsbad, NM, there is the resource of Desert Willow Wildlife Rehab facility. That should be mentioned as well.
Please give me some ideas!
