Lead
The Coachella Valley fringe-toed lizard (Uma inornata) is a species of phrynosomatid lizard.

Ecology, behaviour, and feeding
During breeding season, male lizards minimize time spent foraging for food to maximize time for mating. They preferentially ate readily-available flowers rather than spending time foraging. Female lizards observed an energy-maximizing feeding strategy all-year around.

More specifically, in terms of feeding, the Coachella Valley fringe-toed lizard is omnivorous. Their diet consists of ants, beetles, flowers, leaves, spiders, and sometimes even their own shed skin. This, however, varies on season. During the spring, they tend to consume flowers and plant-dwelling arthropods, and during the summer, this switches to ground-dwelling arthropods and leaves. Adult males and females have different diets only during breeding season, where males consume ants and plants in the mornings, whilst females feed on ants and other insects throughout the day.

The Coachella Valley fringe-toed lizards are talented as they are able to identify when there is an arthropod present underground, and dig them out of the sand to consume. In fact, they are agile and sometimes even jump to catch flowers that are too tall.

Their water consumption is likely through their food.

Habitat and distribution
The lizard is endemic to Coachella Valley, California. The lizard is restricted to habitats with fine, windblown sand deposits in the sandy plains of the Coachella Valley, Riverside County, California. Since the 1970s, estimates of this species' habitat has decreased by about 75% due to human activities. Only a small portion of its original habitat has wind blowing in the fine sand that creates the “blowsand” habitat that it needs to survive.

The Coachella Valley fringe-toed lizard's habitat has been negatively affected in the past 3 decades, due to increases in the human population, urban development, off-roading, and non-native invasive plants. Thus, the Coachella Valley fringe-toed lizard was declared as federally threatened and endangered in 1980.

Unfortunately, there have been severe droughts in California and the Coachella Valley. In 2002, the yearly precipitation was below 10mm. Low precipitation and frequent droughts reduce the growth of plants and food sources for the Coachella Valley fringe-toed lizard. The lack of food sources contribute to a species' survival, thus this may be a cause for the decrease in mean reproductive productivity and decline in mean hatchling numbers and population densities.
