| Action Plan for Australian Frogs: Commissioned to gain an overview of the current conservation status of Australia's frog species, to investigate the possible causes of decline and to determine the actions needed to prevent further losses and to reverse current declines. |
| Bog Frog: The Water Federation provides information about amphibian declines, explaining that because frogs are often among the first to "croak" when ecology is upset, they act as an indicator species for the health of the ecosystem. |
| Deformed Frogs in Minnesota: The Minnesota Pollution Control Agency are studying deformed frogs to determine the cause of the deformities. |
| Frogs: An overview on the decline and conservation of frogs in Australia. |
| Frogs and Toads of Tennessee: Descriptions and photos of species found in this southeastern U.S. state. |
| Hop to It: Irish frog survey organised by the Irish Peatland Conservation Council to find out more about the status of the frog in Ireland. |
| Missouri's Toads and Frogs: Missouri toads and frogs are colorful, harmless, vocal and valuable. Our forests, prairies, rivers, swamps and marshes are home to a multitude of toads and frogs, but few people know how many varieties we have, how to tell them apart, or much about their natural history. |
| Northern Leopard Frog: A description of the leopard frog [Rana pipiens]. |
| Westward Frog: While there is no established cause of amphibian decline, there are many factors known to be potentially detrimental. Here we provide bibliographies for those interested in learning more about these factors. When possible, technical and/or literature reviews are also included. |
| Wetland Science Institute: The use of constructed wetlands in agricultural environments as breeding habitat for frogs. |
