The temporal and spatial characteristics of terrestrial habitat use, especially as it relates to upland use in coastal areas of the species' range, are poorly understood. The majority of potential toad habitat occurs on the San Diego River, with a small amount of possible . It can be recognized by the light-colored, V-shaped stripe across its head and eyelids. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. The San Jacinto watershed area is important because it is at the eastern limits of the species range and is located in higher elevation areas, a nd the Santa Margarita watershed ar ea protects an important. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California.
The known range for a species can be used to constrain the boundaries of the species distribution model and in assessments of the conservation status and/or threats within the range of a species.This dataset represents a species known range extent for Arroyo Toad (Anaxyrus californicus) within the conterminous United States (CONUS) based on 2001 ground conditions. They are completely absent in about 75% of their historic range due to the usual culprits: habitat loss, non-native predators and invasive plant species but also by unnatural water regimes like dam releases and our ephemeral streams running year round due to urban run-off. Potential arroyo toad and coast range newt habitat was initially mapped from stream gradient characteristics through inspection of topographic maps.

This dataset represents a species known range extent for Arroyo Toad (Anaxyrus californicus) within the conterminous United States (CONUS) based on 2001 ground conditions.
This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. The Arroyo toad is a stocky, small toad (5 cm to 7.5 cm) with warty skin that is light olive green, gray, or light brown in color.

Arroyo toads breed in shallow streams; their reproductive biology is generally similar to that of other north-temperate species of Bufo. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use.
