(see below...from his paper AN EASY AND EFFECTIVE WAY TO PROTECT DIAMONDBACK TERRAPIN (MALACLEMYS TERRAPIN) NESTS)


Figure 7 Terrapin tracks in wet sand can lead you to recently laid terrapin nests. If you follow the tracks from the water, they often will lead you to the nest. Specifically, look for the tracks where the terrapin returns to the water, in the left hand panel, this is the left track. You can be recognize the direction of the turtle by noticing the “Js” in their tracks. The turtle is moving in the direction to the top of the J. Arrows indicate the direction of the tracks in the photos. In the right photo, the tracks are moving down the page. Typically, nests will be laid above mean high tide.
This is exciting and helpful information!
Also, Dr. Roosenburg provided great designs for turtle exclosures.
Thanks a lot!
Mr. Forde :-)
