Acknowledgements
The species distribution grids are made possible because of the data freely distributed by the following sources. We appreciate the contributions of NatureServe and the Global Amphibians Assessment to the dissemination of biodiversity data, and in particular NatureServe’s Bruce Young and Conservation International’s Simon Stuart. We also acknowledge the World Wildlife Fund-USA for providing the WildFinder database, which formed the basis for the catalog of species grids.
