The assessment does not paint a rosy picture, but we should read it anyway because it is important to understand the impact of amphibian extinction on other species and their ecosystems. Here is a fact from the executive summary, Disappearing Jewels: The Status of New World Amphibians, which I found particularly chilling:

The Western Hemisphere’s existing system of public and private parks and reserves provides no protection for more than one-third of threatened amphibians (37%), emphasizing the incomplete nature of the protected area system. Even for species that are found in protected areas, management is often not effective at stemming habitat loss. Moreover, threats like climate change or disease transcend park and reserve boundaries.
