New South Boundary Trail Connected

This late afternoon I returned to the SW gate and paint blazed the Southern Boundary Trail. It runs from the SW entrance to the southern end of the Dunes Trail at survey post G0, and the exit from the Woods there. Along the way the trail passes two or three wildlife highways that funnel animals through breaks in the southern fence.. good places for wildlife cameras.
The trail passes through open sunny, drier habitat. There are several patches of young boxelder or honeysuckle that need additional clearing along the way; but the trail is clear enough to follow now. The trail also passes survey posts E0,F0 and D0 (where a short trail is cut going north towards an area of larger diameter trees).
On the west central portion of the trail there are curious bare zones around the bases of many trees..where all the leaf litter has been blown away to the hard soil beneath. It might be good for ecology class to investigate the species of trees with these bare zones and see if any particular species (maybe hackberry,or juniper for instance) is more likely to have a basal bare zone than say elm, oak, ash or pecan might be. Relate to Elroy Rice allelopathy studies.
