Wild populations of frogs, toads, salamanders and other amphibians are declining throughout the world. Scientists suspect greater atmospheric ozone and the increased incidence of ultraviolet radiation, acid rain, and other forms of environmental pollution, but the
exact causes for the rapid disappearance of frogs and other amphibians are unknown. Researchers fear extinction of many species of amphibians worldwide. This decline will reduce the supply of wild frogs for food and for farming operations. It also may impose new regulations and restrictions on frog farming enterprises. In Virginia and most other states, it is lawful to capture and possess no more than a few wild native or naturalized amphibians for private use and not for sale. A permit for capturing, holding, propagating, and selling of wildlife, including amphibians, is required in most states.
