At a recent workshop in California, scientists discussed the decline of amphibian populations and suggested that these animals may be biological indicators of advanced degradation of the environment. One study described the effects of snowmelt contamination with acid deposition from smog and smelters on the breeding ponds of salamanders. Other possible reasons for decline include: heavy metals and pesticides; global climate changes; imbalances in mammal populations that prey on amphibians; predation by fishes stocked in lakes by wildlife managers; and human predation.
