An area of burned southern California chaparral was sampled for reptiles over a period of three years. Six species were observed the first year, ten the second year and eight the third year. As vegetation density and structure changed on a south facing slope, reptile utilization of that area changed, perhaps due to increased habitat availability. Some species showed increased abundance while other species decreased over the three years. The two most abundant lizard species (Sceloporus occidentalis and Uta stansburiana) show a pattern of possible ecological separation by temporal activity.
