The Northern Map Turtle, is a state Endangered Species, found only in the

lower Susquehanna River in Maryland. The only area where nests of this

species are not heavily impacted by predators is in the town of Port Deposit.

However, turtles nesting in Port Deposit must often cross a gravel parking lot

with constant vehicular traffic to reach the nesting sites. Turtles may become

disoriented by human disturbance and move away from the river, towards

Maryland Route 222, the main roadway through the town. In addition, the soil in

which the turtles are nesting is heavily compacted and turtles often abandon

nest sites after unsuccessful nesting attempts.
