The International Union for the Conservation of Nature (IUCN) monitors changes in global biodiversity. It is a network that is composed of both government and nongovernment organizations. The IUCN collects data on the status of the natural world and uses these data to make conservation and sustainable development recommendations. One widely recognized metric for evaluating organismal conservation is the IUCN Red List. This list uses several criteria to calculate the survival probability of organisms throughout the world. The aggregate Red List survival probability for birds, mammals, amphibians, corals, and cycads in different geographic regions is summarized in the table.
Table 1. Aggregate survival probabilities for birds, mammals, amphibians, corals, and cycads according to the IUCN Red List.
