Madagascar’s lemurs could be all but wiped out within the next 20 years unless drastic action is taken, according to primatologists.

Threats to lemurs
All lemur species are endemic to Madagascar, the world’s fourth-largest island and a global “hotspot” of biodiversity. However, these unique primates are under threat from habitat loss and hunting, and recent assessments have found that an alarming 91% of lemur species should be placed in the IUCN Red List threatened categories. This makes lemurs the world’s most endangered mammal group.
One of the greatest threats to lemurs is widespread deforestation. Decades of logging, mining and agriculture have already destroyed 90% of Madagascar’s forests, confining lemurs to the remaining fragments. In recent years, political instability has compounded the problem, forcing many local people to turn to illegal logging and hunting to survive.

According to Jonah Ratsimbazafy, a local primatologist, “If continued at this rate of deforestation, we can say that within 20 to 25 years there will be no more forest and thus no more lemurs.”
Lemur conservation strategy
To tackle the issues facing these charismatic primates, the world’s leading primate experts came together this month to draw up a three-year strategy for lemur conservation. This strategy contains 30 action plans for the 30 different priority sites for lemur conservation, and it aims to help with fundraising for individual projects.
According to Dr Russ Mittermeier, President of Conservation International and Chair of the IUCN SSC Primate Specialist Group, there are three main actions which will be most effective for lemur conservation in the field: “First working on grassroots projects with local communities so people can make a difference for themselves, secondly supporting eco-tourism projects and thirdly establishing research stations as a permanent facility to protect against loggers and hunters.”

Benjamin Andriamihaja of the Institute for the Conservation of Tropical Environments said, “We try to fund activities that generate revenues, like planting beans, rearing pigs and chickens or developing fish farming, so that peasants stop destroying the forest.”
Hard work is yet to come
Speaking about the new strategy for lemur conservation, Dr Christoph Schwitzer, Head of Research at Bristol Zoo Gardens, said, “The fact is that if we don’t act now we risk losing a species of lemur for the first time in two centuries. The importance of the projects we’ve outlined in this document simply cannot be overstated.”

However, he said that he was an optimist and would not give up on any species of lemur, adding that, “This document shows how well people can work together when species are on the brink. I’m proud of what we’ve achieved here but the hard work is yet to come.”
