The Zoological Society of London has produced a map of the world’s most unique and endangered animals.

The Zoological Society of London (ZSL) has produced the first map of the world’s most unique and threatened mammals and amphibians.

Sunda pangolinBlack-and-white ruffed lemurs, the Mexican salamander and the Sunda pangolin all feature on the map, which was released by ZSL yesterday (May 14).

Scientists pinpointed areas of the world where evolutionarily distinct and globally endangered (EDGE) mammals and amphibians occur. Regions containing the highest concentrations of these species are highlighted as global conservation priorities.

The map reveals that high priority conservation areas for mammals and amphibians are different, reflecting the varied evolutionary histories and threats facing the two groups.

For mammals, management efforts are best focused in Southeast Asia, southern Africa and Madagascar. For amphibians, central and southern America are highlighted as priorities.

Jonathan Baillie, ZSL’s director of conservation, said: “The results of the mapping exercise are alarming. Currently only 5% of the areas we’ve identified as priorities for EDGE mammals and 15% of the EDGE amphibian areas are protected.

“These areas highlighted should all be global conservation priorities because they contain species that are not only highly threatened but also unique in the way they look, live and behave. These new maps will inform the development of larger-scale work to help secure the future of some of the most remarkable species on Earth,” Professor Baillie added.

Madagascar’s black-and-white ruffed lemur is the largest lemur in the world and is threatened by hunting and the loss of its forest habitat to logging, mining and cutting and burning for agriculture. The Sunda pangolin, also known as the scaly anteater, occurs in Southeast Asia and is threatened by illegal poaching for its meat which is a culinary delicacy, as well as its scales, which are thought to have high medicinal value.

Black and white ruffed lemurOther mammal species occurring in priority areas include the black rhino and western lowland gorilla.

Amphibians face the highest rate of extinction, making them the most threatened vertebrates in the world.

The Mexican salamander, or axolotl, is critically endangered due to urbanisation, polluted waters, and the introduction of non-native fish that eat the axolotl’s young. With the aid of the global map of EDGE amphibians, it will now be possible to concentrate efforts in countries such as, Mexico, Costa Rica and Guatemala where the most distinct and threatened species are found.

Kamran Safi, lead author of the paper from the Max Planck Institute for Ornithology said: “This is the first global map to take into account species’ uniqueness as well as threat. Now that we’ve identified EDGE priority areas for mammals and amphibians we can more effectively continue to ensure their protection.­”

The research paper has been published in PLOS ONE and an interactive version of the EDGE map can be found at the EDGE website.
