Fun Fact

 The skin color of the blunt-nosed leopard lizard varies according to what they eat and the type of soil in their habitat, ranging from yellowish or light brown to dark brown.

Habitat

This species spends most of its life in terrestrial habitats such as grasslands, oak woodlands, scrub, and chaparral in washes and floodplains. This species relies on temporary pools of water to breed. These include vernal pools, seasonal runoff, pools in creek channels or off-channel, and cattle ponds. Restoration and management of vernal pools and other temporary pools do not require imported water.

Disturbance and stressors

Housing development, agricultural cultivation, oil and gas development, and solar development contributed to the decline in blunt-nosed lizard populations. Additionally, above-average precipitation decreases species survival while below-average precipitation decreases species reproduction.
