The rapid decline of the Sierra Nevada yellow-legged frog population can be attributed to several factors, including:
- **Fish**: The introduction of non-native fish species has had a significant negative impact on the frog population as they prey on frog eggs and tadpoles.
- **Fungus**: Chytridiomycosis, a disease caused by the chytrid fungus (Batrachochytrium dendrobatidis), has been a major factor in the decline of many amphibian species, including the Sierra Nevada yellow-legged frog.
- **Pesticides**: The use of pesticides can contaminate aquatic habitats and affect the health and survival of amphibians.
- **UV Radiation**: Increased ultraviolet radiation, due to the depletion of the ozone layer, can harm the development of frog eggs and larvae.
- **Pollution**: Various forms of pollution, including chemical runoff, can degrade the quality of aquatic habitats and negatively affect frog populations.
All of the factors listed can contribute to the decline of the Sierra Nevada yellow-legged frog population.
