Postfire Plant Community at Low Elevation, Death Valley NP
Photo of a low elevation community that burned four years prior in the Calico fire, Death Valley National Park. Notice the large amount of plant cover, a large proportion of which is dominated by invasive species like red brome (Bromus rubens) and red-stemmed filaree (Erodium cicutarium).

Unburned Plant Community, Death Valley NP
This is a low elevation community that is unburned. It is immediately adjacent to the Calico fire perimeter (Death Valley National Park). The large amount of herbaceous plant cover (mainly red brome Bromus rubens and red-stemmed filaree Erodium cicutarium) in the understory make this extremely susceptible to burning.

Western Skink
The Western skink (Plestiodon skiltonianus) is a relatively common and widespread lizard in Southern California. It is more secretive and prefers more grassy habitat than the Western fence lizard or the side-blotched lizard, yet USGS and National Park Service biologists are finding signs of genetic isolation in all these species.
