This lizard and several skinks are the only lizard species in the park. It is common throughout Virginia, one of the links in the ecosystem energy flow. Sixty years ago the Eastern Fence Lizard was grouped with several other species in a sub-family aptly called Swifts (just try to catch one). But taxonomy is constantly changing and that grouping has fallen by the wayside. It now belongs to the family Phrynosomatidae; try to say that without tripping!
