The Duke Lemur Center recognizes that our work to protect lemurs here at Duke University and in cooperation with other AZA (Association of Zoos and Aquariums) accredited organizations is not enough: we must also take action to protect lemurs in their natural habitat in Madagascar. We’re proud to work with the organizations and people of Madagascar to create opportunities for positive change, and to play a leading role in preventing the island’s legendary population of endemic and endangered national treasures from being lost forever.
Why lemurs and Madagascar matter
Madagascar is the fourth largest island in the world and features some of Earth’s most amazing and diverse biological life. Isolated for nearly 150 million years, the plants and animals of Madagascar spent millions of years evolving their own unique characteristics, not to be found elsewhere on the planet. Remarkably, the more than 100 species of lemurs found in Madagascar exist naturally nowhere else on earth. Such extreme endemism is characteristic of all forms of life on this oceanic island with 98% of the mammals, reptiles, and amphibians and over 90% of the (more than 12,000) plant species being found nowhere else on the planet.
The sheer size of Madagascar (nearly 1000 miles long and 350 miles wide) coupled with the diversity of Madagascar’s regional climates and habitats – desert, lowland and high altitude rain forest, dry deciduous forest, mountains and valleys, grasslands, spiny forest and knife-edged limestone formations – creates such a vast array of habitats for wildlife and plants that Madagascar is often referred to as the “Eighth Continent.”

Like humans, lemurs are primates. In fact, lemurs and other prosimians like bushbabies and lorises are the most ancestral primates and evolved long before monkeys, apes, and humans. While ancestral lemurs disappeared elsewhere in the world, they thrived on Madagascar. Isolated on the tropical island for millions of years, with ample resources and few predators or competition, the animals evolved and diversified to fill the island’s many ecological niches.
Because of their evolutionary age and incredible variety of lifestyles and adaptations, the lemur branch of the primate family tree is particularly interesting to scientists. As fellow primates, we can learn more about ourselves – and our evolutionary past and potential – by non-invasively studying these “living fossils.” For example, some lemur species develop the same plaques and tangles seen in the brains of humans diagnosed with dementia and Alzheimer’s disease. Others go into seasonal torpor, a form of hibernation, which is unique among primates. Studying these traits in lemurs provide key clues about primate evolution and also now hint at exciting scientific discoveries that will impact humans.
Since humans arrived on the island 4000 years ago (Dewar et al. 2013), tremendous deforestation and animal extinctions have occurred. Less than 16% of Madagascar is now covered in forest, and within last 60 years, forest cover has decreased by nearly 40% (Harper et al., 2007). At least 17 species of lemurs (ranging in size from 10kg to 160kg) and many other megafauna, such as the 10-foot-tall elephant bird, recently went extinct. Currently, lemurs are considered the most threatened mammal group on earth (Schwitzer et al., 2014).
The island’s human population has ballooned to over 24 million, with more than three-fourths of the population living on less than $1.25 per day. People farm the land to feed their families using traditional methods of slash-and-burn agriculture, which results in loss of soil fertility, erosion, wildfires, and stream sedimentation. Ultimately, the soil is depleted and new patches of forest are burned to create more farmland, with the result that subsistence agriculture is a primary driver of forest loss. The need for land has grown exponentially with Madagascar’s population, which is expected to double by 2050; and the unique biodiversity of Madagascar continues to suffer. Conservation, as the Duke Lemur Center practices, must meet the needs of local communities in addition to protecting the amazing fauna and flora of Madagascar.
At least 17 species of lemur have gone extinct, and the existing lemurs are the most threatened group of mammals on Earth. An assessment by the International Union for the Conservation of Nature (IUCN) in 2012 identified 94% of the remaining 103 lemur taxa as threatened, compared to 74% only four years prior.
It's a race against time to preserve lemur populations, and conservation programs both ex situ (managed care/zoos) and in situ (in the wild) are vitally needed.

How we’re helping in Madagascar
The DLC’s focus extends to both in-situ and ex-situ lemur populations on their native island of Madagascar. While our in-situ conservation initiatives focus on lemurs living in their natural habitat (Madagascar’s forests), our ex-situ initiatives address the conservation and care of lemurs living away from the forest in zoos and conservation centers across the island. Ex-situ conservation measures complement in-situ methods in that they provide a genetic safety net (or “insurance policy”) against a species’ extinction in the wild. These measures also have a valuable role to play in recovery programs for endangered species.

The Duke Lemur Center has been involved in conservation efforts in Madagascar for over 30 years. Since the founding of the DLC-SAVA Conservation program in 2011, the Lemur Center’s in situ (in the wild) conservation efforts have been focused within the SAVA region of northeastern Madagascar (Sambava, Andapa, Vohemar, and Antalaha). Led by DLC Conservation Coordinator Charlie Welch, the program involves Malagasy staff and Duke students and faculty, all partnering with Malagasy organizations to achieve its conservation goals.
We firmly believe that conservation in Madagascar will be most successful when:
(1) strategies are informed by carefully collected data on how lemurs and humans interact with their natural environment; and
(2) the next generation of Malagasy leaders are inspired by, and have the resources to protect, the remarkable biodiversity of their island home.
For more than fifty years, the DLC has built its reputation as a world leader in understanding and caring for lemurs, and our expertise is sought and respected by ex-situ institutions and zoos around the world - including Madagascar! The DLC has partnered with the Government of Madagascar’s Wildlife Department to advance the state of lemur husbandry and breeding management in Madagascar’s zoos: two national zoos and 12 privately-owned zoos, constituting a total of 645 lemurs across 20 endangered species.
DLC is a founding and managing member of the Madagascar Fauna and Flora Group (MFG), a consortium of zoos and other institutions committed to supporting conservation in Madagascar. MFG projects in Madagscar focus on community-based conservation techniques operating in the area around Betampona Natural Reserve and Parc Ivoloina on the east coast.
Parc Ivoloina is a regional conservation center on Madagascar’s east coast, which includes a small zoo and focuses on activities such as environmental education and sustainable agricultural practices.
Betampona is a protected natural forest and also the site of the first reintroduction of captive-born lemurs back to the wild, a collaborative DLC/MFG effort. The reintroduction has evolved into an important program of conservation research and ecological monitoring, with education and reforestation components linked to nearby Ivoloina. Thanks in part to DLC support and MFG presence in Betampona, the reserve has been protected from illegal wood cutting and poaching of wildlife. "Perhaps the most valuable result of the restocking program is that the release project became the springboard for a much broader conservation program for Betampona,” says DLC conservationist Andrea Katz.

Ivoloina is the site of more than 20 years of conservation work by the Madagascar Fauna Group, of which Duke Lemur Center is a founding and managing member. Charlie and his wife Andrea Katz worked here for 15 years, while living in Madagascar.
The Duke Lemur Center is a major resource for undergraduate and graduate student education. Duke ENGAGE and Duke Engineers for International Development (DEID) send undergraduate volunteers to work in the SAVA region of Madagascar, as well as other Duke groups such as Duke Global Health Initiative. All are facilitated by DLC-SAVA.
We’re making a difference — and you can help!
