The shape of the opening suggests it is a Gopher Tortoise burrow. There seemed to be tracks at the entrance. which indicates it is active.
The preserve has not had a gopher tortoise population in the time I have been monitoring it. I have seen two gopher tortoises of unknown origin, but they did not persist. I found one of them dead. Not sure what became of the other one.
As noted in an earlier post, I recently found the empty shell of a Florida Box Turtle. but they do not dig burrows, so I can rule out that species as the occupant.
I will have to recheck the area from time to time to document what is happening.
