The species of amphibians that are currently present in the Baldwin Hills are remnant populations of species that have adapted to urbanization. As a whole, Baldwin Hills supports a low diversity of amphibians at this time. Historically as many as six amphibian species may have occurred. Continued habitat loss and degradation, especially in ephemerally wetted habitats, has contributed to the decline in amphibian richness. Species composition and abundance is directly related to the amount of suitable habitat that is available. Artificial drainage and artificial water course provide limited habitat values for amphibians in the area.
