Ring-tailed lemurs are found on the south-western tip of Madagascar in scattered populations from Tolagnaro in the southeast, to Morondava on the west coast, and Ambalavao inland, with a single isolated population at the Andringitra Masif on the southeastern plateau. Population densities are estimated at 100 individuals per km2 in dry forests to 250-600 individuals per km2 in gallery and secondary forests. Wild populations have plummeted 95% since 2000 and the most recent estimate is 2000-2400 ring-tailed lemurs left in the wild. In 2009 there was an estimated 2500 individuals in zoos, meaning we have now reached a point where there are more in captivity than in the wild!
There are multiple threats facing ring-tailed lemurs and causing the population decreases over the last 2 decades noted above. The number one reason is habitat loss. Their forest areas are being decimated by humans for farmland, grazing for livestock, and regular burning for the coal industry. This is leading to severely fragmented forest areas suitable for the lemurs to call home, and further isolating populations, which would reduce genetic diversity in the gene pool. Another major cause of population decline is the unsustainable hunting for the bushmeat trade as a local food source for humans. Bushmeat has now gained popularity all over the globe as an exotic delicacy. This has increased the illegal push for these imports in many at risk populations of animals all over the world. A third concern for these lemurs is the capture for illegal pet trade. It has been common practice to have them as part of a private collection in many parts of their nation.
The ring-tailed lemur went from Near Threatened status to ENDANGERED in 2014. This is a direct result to the devastating decline in the population and ongoing habitat loss they are facing. As such, there has been multiple protections put in place to try and help this species. They are listed on Appendix I of CITES, which is an international agreement between governments to severely limit the exportation/importation of endangered species. This makes most trade illegal and difficult. There are multiple conservation sites that have been identified in Madagascar with protected areas put in place. The problem is these areas are small and fragmented with illegal activities still occurring there.
According to IUCN the following conservation actions need to take place: land/water protection (resource & habitat protection), land/water management (site/area management and habitat & natural process restoration), species management (harvest management), education & awareness, and law & policy (compliance and enforcement at the local & national level).
There are local groups, such as Anja Reserve who are a prime example of what we can do right. The locals in this area have embraced the conservation efforts for the ring-tailed lemur and self-regulate and enforce their protections. They are now benefiting greatly from ecotourism. Proving that protecting the lemur and giving up close tours from visitors all over the world can provide their families with better quality of life and financial means, than farming that land or hunting the lemurs. There is also a large captive lemur population in the United States on St Catherine's Island in Georgia. There they are studied and part of a breeding program. The hope of this program is to understand them better and be able to release some of the captively bred population back into the wilds of Madagascar. As mentioned previously, there are about 2500 ring-tailed lemurs in captivity around the world. Lemurs in zoos play a very important role in conservation as well. Zoos raise awareness of species people would otherwise never see in their lifetime. They put a face to the human caused plights of so many at risk species. When they are seen by people at the zoo, we become impassioned and inspired to do something to save these fragile lives.
Habitat Restoration
In addition to these efforts, you can also make a difference. You can donate to organizations in Madagascar that are on the ground there trying to make a difference. You can share information about them and inspire others to be passionate about lemurs as well. There are links on the website for lemur conservation.org below, where you can even go volunteer in Madagascar for 2 weeks to a year! But the biggest way you can make a difference for this species, and so many more facing the same fate is to reduce your carbon footprint. Shop locally and ethically, reduce your waste and energy consumption, and be an advocate for the environment. Anthropogenic global warming (caused by humans) is the number one threat of extinction for many species and is even a threat to our own species. It is destroying ecosystems and displacing plants and animals all over the planet at an alarming and unprecedented rate.
Conservation efforts for the ring-tailed lemur are very important. They fill a critical ecological niche in the creation of habitats through seed dispersal, as well as have a vital role in the Madagascar food web. Failure to conserve this species will result in the collapse of the ecosystems of this fragile region. This is because the plight the ring-tailed lemurs face is the same plight many other species in the same region face, for much of the same reason. By focusing our efforts to regain habitats in critical lemur areas, we will be aiding in the conservation of many at risk species in the same area. The ring-tailed lemur is the most well recognized poster child for this region, so concentrating our efforts here will have far reaching benefits for all the Madagascar flora and fauna. Will you stand by and watch one more critical species disappear from existence?
