Florida Scrub Lizard
Sceloporus woodi · also called Florida scrub lizards
Across a patch of open, sandy Florida scrub kept naturally clear by periodic fire, a Florida scrub lizard darts between clumps of low vegetation, a species found nowhere else on Earth and increasingly confined to isolated fragments of a habitat that development and fire suppression keep shrinking.
Overview
The Florida scrub lizard, Sceloporus woodi, is a small, sandy-coloured lizard native exclusively to scrub habitat scattered across peninsular Florida. Its complete dependence on one naturally patchy ecosystem, indirect reliance on periodic fire to maintain that habitat, and increasingly fragmented population make it one of the more conservation-significant reptiles found in the state.
A lizard tied to one very specific kind of ground
Few reptiles depend as completely on a single, narrowly defined habitat type as the Florida scrub lizard does on Florida scrub, a dependence that leaves the species with nowhere to go as that habitat continues to shrink and fragment.
Status
Vulnerable, with populations declining due to habitat loss and fragmentation from development and fire suppression across its scrub habitat in peninsular Florida.
Florida Scrub Lizard: common questions
Why is the Florida scrub lizard found nowhere else in the world?
This species has adapted specifically to Florida scrub, a naturally patchy ecosystem of sandy soil and low, drought-adapted vegetation found only within peninsular Florida, and its physiology and habits are tied closely enough to this specific habitat type that the species has never established populations anywhere else.
Why does the Florida scrub lizard need periodic fires?
This species depends indirectly on the natural fire cycles that historically kept Florida scrub habitat open and low in vegetation, since without periodic fire, scrub habitat can become overgrown with denser vegetation that eliminates the open sandy ground the lizard needs for basking, foraging, and moving quickly to escape predators.
Why is the Florida scrub lizard considered vulnerable?
This species has experienced significant habitat loss and fragmentation as Florida scrub has been cleared for coastal and inland development, and remaining patches are further degraded by fire suppression allowing overgrowth, together leaving many populations small, isolated, and vulnerable to local extinction.
How can you identify a Florida scrub lizard?
Look for a pale, sandy-brown body with a dark stripe running along each side, a pattern that blends closely with the open sandy ground of its scrub habitat, combined with a smaller, more slender build than several other spiny lizard relatives in its genus.
