Our program generally focuses on primate research and conservation, with a focus on lemurs. We are concerned with how lemurs negotiate survival and reproduction in dynamic environments.
Most work is conducted in Ranomafana National Park in southeastern Madagascar, but we also do work at Kianjavato and Tsinjoarivo with our collaborators.
What Lemur Species We Study
The majority of our research is conducted with red-bellied lemurs (Eulemur rubriventer), but we are also involved in research with other species, such as the brown mouse lemur (Microcebus rufus), Milne-Edwards sifaka (Propithecus edwardsi), and Diademed sifaka (Propithecus diadema).
How We Support Local Communities
We engage directly with community members in several ways. We hire local experts to help us conduct our research. We train students and locals without formal education in scientific principles and date collection.
We collaborate with researchers and Centre ValBio staff on grant proposals and research. And, we communicate our research at all stages through disseminating publications, giving presentations to officials, tourism guides, faculty, and students, and co-mentoring students.

At The Institute of Zoology at the University of Veterinary Medicine Hannover we help protect lemurs through on-the-ground research, capacity building, and captive management.
The working group “Lemur conservation Biology” from the Institute of Zoology has worked in the Ankarafantsika National Park (135,000 ha park) since 1995 and in the Mariarano forest since 2003. The Ankarafantsika National Park comprises the largest remaining patch of continuous dry deciduous forest in northwestern Madagascar and is therefore of utmost importance for the preservation of the remaining biodiversity.
How We Protect Lemurs And Other Wildlife
The Institute of Zoology in Hannover undertakes cutting edge research on lemurs both inside and outside Madagascar. One of our major aims is to increase understanding of how nocturnal lemurs have adapted and evolved in their respective environments.
In particular, the Institute studies the patterns, evolution, and consequences of differences between species in their behavior, bioacoustics, ecology, and susceptibility for diseases. Combining this knowledge with an understanding of how habitat needs and habitat fragmentation impact the genetic diversity of populations,it is possible to evaluate the changes for long-term survival of these populations.
In addition to our work in the field, the Institute of Zoology also leads the ex situ management of Goodman’s mouse lemur (Microcebus lehilahytsara), and keep one of only two breeding colonies worldwide for this species.
What Lemur Species We Protect

In the Ankarafantsika National Park, our work impacts:
Golden-brown mouse lemurs (Microcebus ravelobensis), described by the Institute in 1998
Mongoose lemurs (Eulemur mongoz)
Grey mouse lemurs (Microcebus murinus)
Fat-tailed dwarf lemurs (Cheirogaleus medius)
Brown lemurs (Eulemur fulvus)
How We Support Local Communities
Species and habitat conservation cannot be achieved without involving the Malagasy community and their active participation in decision-making processes. As a prerequisite, any conservation initiative must therefore aim to strengthen local knowledge and to raise responsibility for the unique biodiversity of Madagascar.
Since 1995, the Institute of Zoology has established a series of collaboration contracts with Malagasy authorities including the University of Antananarivo (Department of Zoology), the University of Mahajanga (Biology Department), and Madagascar National Parks (MNP). These are key to the long-term success of the programs and to build capacity in Madagascar for lemur conservation.
Specifically, the Institute aims to:
jointly perform research projects and publish scientific results with Malagasy collaborators
improve access of Malagasy partners to scientific results from the international research community
provide institutional support for Malagasy universities and collaborators
increase scientific networking with Malagasy colleagues
support and mentor Malagasy students, postdocs, and researchers
contribute to local capacity building of students and local field assistants
School children with the Madagasikara Voakajy lemur mascot!
At Madagasikara Voakajy we promote conservation, and sustainable use of Madagascar’s unique species, habitats and ecosystems, for the benefits of Malagasy people.
Madagasikara Voakajy was established in 2005 to provide job opportunities for young Malagasy researchers. Over time, we have evolved to become an organization that provides opportunities for Malagasy biologists to become leaders in the conservation and ecological study of a wide variety of species.
Nowadays, we use evidence-based interventions and stakeholder engagement to target our conservation of species and their habitats. Currently, we have teams of experts who focus on baobabs, bats, reptiles, amphibians and lemurs.
How We Protect Lemurs And Other Wildlife
We monitor four species of lemur, having implemented a monitoring program using occupancy modeling, a method that could be implemented easily with the local communities. In the Alaotra-Mangoro region, our interventions benefit at least seven other lemur species.
Hunting for lemurs in the Alaotra-Mangoro Region (where Madagasikara Voakajy does much of its work) is a real problem. Our research on this topic has found that lemur hunting may be widespread in this region and may be increasing. In addition, the traditional taboos that some groups in this region hold against hunting some lemur species (like the Indri) may be breaking down. Since 2015, the monitoring of threats and pressures has been carried out. Only Ayes-ayes now remain taboos for the hunters.
In October 2015, we started using camera traps to monitor lemurs and other animal species in Mangabe protected area (Moramanga district). This method provides valuable information on the presence / absence, behavior and habitat use of lemurs.
What Lemur Species We Protect
Currently, Madagasikara Voakajy directly impacts the following lemur species:
Common brown lemur (Eulemur fulvus)
Indri (Indri indri)
Diademed sifaka (Propithecus diadema)
Alaotra gentle lemur (Hapalemur alaotrensis)
How We Support Local Communities
Madagasikara Voakajy has worked to create several protected areas and natural resources use programs in Madagascar.
Outreach
Given the high rates of lemur hunting in our target region, Madagasikara Voakajy undertakes awareness campaigns of the protected status of lemurs with both children and adults. For example, ‘Lenari’, our Indri mascot, interacts with audience members at outreach events through playing, singing and dancing. ‘Lenari’ makes appearances at the organization’s events which include animal festivals, drawing competitions, song and poem competitions, field trips, and even the creation of school biodiversity clubs.
Now, the SOS project, “Youths for lemurs – Lemurs for youths”, sees young people aged 15-25 from the villages around Mangabe, participate in the conservation of lemurs. Young people make song contests, interviews on lemur conservation and broadcast radio programs to raise awareness of the importance of lemurs amongst their communities.
Madagasikara Voakajy trains Malagasy scientists both at the university level and beyond.
Madagasikara Voakajy also undertakes outreach in schools. Our partnership with education authorities at the local level is especially helpful with schools located in communities that are within the boundaries of new protected areas.
Capacity building
Through our student training program, Madagasikara Voakajy continues to nurture the next generation of Malagasy scientists.We are also aiming to build the careers of promising Malagasy biologists through employment within the organization.
Here at Planet Madagascar we support lemur conservation in northwest Madagascar through focused outreach and education programming.
We undertake lemur conservation efforts in and around the Ankarafantsika National Park, in northwestern Madagascar. These are primarily focused in three communities: Ambarindahy, Maevatanimbary, and Andranohobaka.
The organization very purposefully implements one project at a time, at a relatively small scale, so that we can work with the three communities on an ongoing basis. Over the next few years, Planet Madagascar will focus on conservation education, fire management, and community livelihoods programs.
In the future, we aim to expand outside of the three communities. We are working hard to seek funding through grants and private donations to fund our projects.
How We Protect Lemurs And Other Wildlife
We work with local communities to help preserve and replenish remaining habitat for lemurs and other wildlife. There are two key areas:
Fire Management
Planet Madagascar works with local community members, including national park staff, to find and implement realistic solutions to bush fires, one of the major threats affecting lemurs in the park. Local residents burn grasses near forest to improve grazing zones for cattle, but fires also accidentally burn forest.
Planet Madagascar staff.
We are working with the community to implement a fire management strategy while contributing to improving the livelihood of people living in the communities. This strategy will provide employment for local residents and also mitigate fire risk for lemurs and their habitat.
Reforestation
We work to cultivate and plant new trees in Ankarafantsika National Park. We focus on two types of restoration: restoring fragmented landscapes to create corridors that connect existing fragments to continuous forest, and erosion control through forest restoration where we plant trees to reduce the impact of erosion.
We hire and train local community members to work with our on-the-ground Planet Madagascar staff members to identify target plant species, collect seeds, build and manage tree nurseries, and plant seedlings. Community members benefit through a salary-based program, thereby providing them with much-needed revenue and by receiving the direct benefits of erosion control through forest restoration.
What Lemur Species We Protect
Planet Madagascar’s work in and around the Ankarafantsika National Park in northwestern Madagascar currently impacts the following lemur species:
Local people are involved at all stages of Planet Madagascar’s projects, as one of the goals of the organization is to develop capacity in Madagascar. Before implementing any project, Planet Madagascar holds stakeholder meetings with community members to facilitate open discussion about the challenges faced by conservation efforts, and to work out collaborative solutions and action plans. Then, while programs are being implemented, relevant members of the community are trained to manage and continue the programs. We endeavor to provide local communities with the tools they need to continue the work and educate themselves about the importance of the conservation projects.
Conservation Education and Community Livelihoods
In September 2014, Planet Madagascar completed a livelihoods survey, speaking with 213 community members in their three target communities. Preliminary results revealed that over 70% of the people did not have knowledge of the different lemur species in their region, and few people were aware of the benefits that lemurs provide to forest ecosystems. For example, in one village, only 8% of people were aware that lemurs disperse seeds. We found that people’s livelihoods depend on the national park and its resources. For example approximately 70% of the respondents stated that their livelihoods depend mostly on the park for food, water, and economic activities.
These results underline the importance of implementing education and development programs in these communities and serve as a baseline dataset that allows Planet Madagascar to measure the impact of projects and education initiatives.
Lambas for Lemurs Lambas for Lemurs, was funded by Primate Conservation, Inc. and the Rufford Foundation and began in April 2015. Its goal is to raise awareness about lemurs and their role in the survival of the entire ecosystem. To implement this program, Planet Madagascar created an education toolkit that consists of guidelines and activities for adult leader training sessions, children’s educational programming, and adult educational programming. To reinforce the conservation message, we printed lambas (Malagasy clothes similar to a sarong) and gave them to participants. Lambas are traditionally a culturally relevant medium of knowledge transfer. On each lamba we printed a scene depicting lemurs living in forest alongside people, and a message that states in the local dialect of Malagasy that “a healthy forest has lemurs.”
Women’s Cooperative
In 2017 we helped create a new women’s cooperative focused on sustainable agroforestry and forest restoration. We plan to expand from sustainable agroforestry and forest restoration to other projects including sanitation, women’s health, and education.
Educational Documentary Along with renowned wildlife filmmaker, Chris Scarffe, Planet Madagascar gathered footage for an educational documentary, aimed at a Malagasy audience. Using Ankarafantsika National Park as a case study, the aim is to create a film that highlights issues related to human-wildlife interactions in Madagascar and illustrate why a healthy ecosystem is beneficial to both humans and nature. This will help facilitate dialogue in the local communities in a way that helps people understand how their actions have direct impacts on the surrounding wildlife and ultimately on their own livelihoods.

What We Do
Critically endangered mongoose lemur born at LCF in 2014.
The Lemur Conservation Foundation (LCF) helps conserve lemurs through managed breeding programs, outreach, and on-the-ground conservation in northeast Madagascar.
We are a non-profit corporation dedicated to the preservation and conservation of the primates of Madagascar through managed breeding, scientific research, and education. The foundation (and accompanying lemur reserve) focus on fostering natural lemur behavior to encourage a dynamic population.
LCF supports educational programs started by the late Dr. Alison Jolly in Madagascar and is developing content to bring those programs to classrooms in the United States. In addition, LCF provides financial support to assist in the establishment of a tourist and research camp in Anjanaharibe-Sud Special Reserve in northeast Madagascar, home to the elusive Silky Sifaka and a unique population of Indri with black pelage.
How We Protect Lemurs And Other Wildlife
LCF has partnered with the Madagascar National Parks in Anjanaharibe-Sud Special Reserve (ASSR) to provide boundary demarcations for this protected area and a site called Camp Indri which provides base camp for tourists and researchers. This helps protect habitat for lemurs and other wildlife.
Demarcation signs funded by LCF to outline the boundary of the Anjanaharibe-Sud Special Reserve.
Ex-situ we operate a 100 acre reserve in Myakka City, Florida. The reserve is set up with two semi free-ranging forests, each approximately ten acres, and two traditional enclosure buildings. As a Certified Related Facility with the Association of Zoos and Aquariums, LCF participates in the Eulemur Species Survival Plan (SSP), Ruffed Lemur SSP, and Ring-tailed Lemur SSP, which include a global network of institutions working towards the propagation of selected lemur species in order to ensure the healthy existence of those species whose survival is in peril.
LCF also hosts field training programs, in which professors and their students utilize the facility and the lemur colony for behavioral observations and research on social dynamics and cognitive skills, as well as habitat use and food selection. These training programs produce future primatologists and conservation biologists which will carry the conservation imperative forward for lemurs and other endangered species. Fostering and inspiring conservation based careers is an invaluable part of LCF’s mission.
What Lemur Species We Protect
At our reserve in Florida, we house over 45 lemurs of six different species, most of which are critically endangered or endangered. LCF is a Certified Related Facility with the Association of Zoos and Aquariums and participates in their Species Survival Plans which work to maintain a genetic safety net for a variety of lemur species. The species currently at the reserve are:
A family of Lemur catta in one of LCF’s semi free-ranging forests, where field students can observe lemurs in a natural environment.
Collared lemur (Eulemur collaris)
Mongoose lemur (Eulemur mongoz)
Sanford’s lemur (Eulemur sanfordi)
Common brown lemur (Eulemur fulvus)
Red ruffed lemur (Varecia rubra)
Ring-tailed lemur (Lemur catta)
LCF is supporting projects in Anjanaharibe-Sud Special Reserve (ASSR), a large mountainous rainforest in northeastern Madagascar, which has long been recognized as a lemur priority site. At least 11 lemur species are found here including:
We have the pleasure of continuing Dr. Alison Jolly’s legacy with the Ako Project, in collaboration with Dr. Hanta Rasamimanana, Dr. Jolly’s former colleague, professor at ENS, and Madagascar’s “Lemur Lady”.
The first book in the Ako Project series, Ako the Aye-Aye.
The Ako Project, sponsored by EnviroKidz, is an educational children’s book series, translated in both English and Malagasy, which is intended to teach Malagasy children about different species of lemur in a fun, tangible way. The books come with matching curriculum to help teachers convey the conservation themes and concepts envisioned for the stories.
Training support
LCF also collaborates with École Normale Supérieure (ENS), the teachers’ training arm of the University of Antananarivo. This partnership supports the students of ENS in their field research and field work theses at the Berenty Reserve, a private wildlife reserve in southern Madagascar. Research done at Berenty includes lemur census surveys and plant phenology.
WWF Madagascar has been at the forefront of lemur conservation in Madagascar for over fifty years. Our first ever project involved setting up a small reserve dedicated to the protection and prosperity of the Aye-aye (Daubentonia madagascariensis), leading to the creation of the Nosy Mangabe special reserve. Since then, lemurs have remained some of the organization’s priority species at our project sites across the island.
How We Protect Lemurs And Other Wildlife
Habitat protection
WWF has been, and continues to be involved in, the establishment and management of many protected areas across Madagascar, which serve to conserve and protect threatened habitats for many lemur species as well as a wide variety of other flora and fauna. In addition, WWF Madagascar carries out a range of actions in Madagascar aimed at protecting habitat. For example, in the Northern Forest Landscape, WWF trains and equips local communities to perform forest patrols. One of the functions of the patrols is to collect information on species locations and populations. Both the presence of the patrols and the data they collect are being used to combat poaching of lemurs and other animal species.
WWF are currently working on habitat protection issues across Madagascar in many sites, including: Marojejy, Kirindy Mitea, Tsimanampesotoe, Amoron’i Onilahy, Ankodida, Corridor Marojejy Tsaratanana, Anjanaharibe Sud, Nord Ifotaka, and Ranobe PK 32.
Influencing environmental policy
WWF Madagascar, and WWF as a whole, are able to raise awareness of the threats facing lemurs at the national and international level. An example of the positive impacts of our work include WWF’s debt-for-nature concept, which pioneered the idea that a nation’s debt could be bought in exchange for in-country conservation programming. WWF has used this program to generate over $50 million (USD) of funding in Madagascar for conservation from 1989 to 2008. In addition, WWF Madagascar was a key facilitator in the First International Conference on the Conservation of Nature and Natural Resources in Madagascar; this meeting was the foundation of the National Environmental Action Plan that was later implemented in Madagascar in the 1980s.
What Lemur Species We Protect
An Aye-aye (Daubentonia madagascariensis).
Over the years, WWF Madagascar has been key to the protection of many different lemur species. Nowadays, and alongside ongoing projects to protect numerous lemur species, WWF’s strategy identifies the Silky simpona (Propithecus candidus) as one of our flagship species for the Northern Forest Landscape, the largest remaining stand of humid forest in Madagascar.
In 2011, WWF, in collaboration with Dr. Erik Patel, and international expert on the Silky simpona, conducted a vulnerability analysis on this species; the first of its kind. This groundbreaking research helped conservationists understand more about the different threats facing a species, and was expanded in 2012 in collaboration with the IUCN (International Union for Conservation of Nature) and again in 2014 with the help of GERP. This research now helps scientists and organizations better plan their conservation programs.
WWF Madagascar has performed fieldwork to collect vulnerability data and information on species viability. The has helped to understand the factors that render the Silky simpona vulnerable, in order to start implementing adapted management measures that will help the species to face future climate and non-climate pressures.
How We Support Local Communities
WWF puts local communities at the center of conservation projects. Local communities that live closest to valuable, fragile lemur habitats are pivotal to the success of lemur conservation because they are the ones interacting with, living in and depending on the forests and species on a daily basis.
WWF manages a wide array of social development programming; in the past, the organization has developed eco-tourism projects, designed public health programs, and even worked with the Malagasy government to create eco-labels for Malagasy shrimp which are traded on the international market through the shrimp aquaculture industry.

Local conservation management
In the Northern Forest Landscape, a green belt composed of 39 community-based managed areas is being established around the created protected area of COMATSA (245,000 ha). Each area managed by local communities first undergoes a zoning process and then local management plans are developed. As the Silky simpona is a flagship species for the entire area, activities related to its conservation and resilience building will be developed for the protected areas as well as for all the community-managed areas where the species is present.
Environmental education
Since 1987, WWF Madagascar has been growing its environmental education program, in collaboration with the Malagasy Ministry of Education. The program now has 515 student clubs across 46 districts in Madagascar and impacts over 50,000 students in the country. In addition, the program also prints the Vintsy Magazine, an environmentally focused publication, which has been in print for 64 issues.
Biodiversity Conservation Madagascar (BCM) was established in 2002 as the conservation arm of Bioculture (Mauritius) Ltd. Our main goals are to conserve threatened forests in east and west Madagascar that are of high biodiversity value, especially those rich in lemur species. We currently work in the 2,400 hectare lowland rainforest in Sahafina (East Madagascar) and the Beanka dry deciduous forest in the Maintirano region (West Madagascar).
How We Protect Lemurs And Other Wildlife
BCM manages the conservation of two forests on behalf of the Malagasy government through “Conservation Leases.” Since 2003, we have been responsible for the protection of 2,400 hectares of humid low altitudinal forest in eastern Madagascar. In 2007, BCM started managing a second site—the Beanka New Protected Area in Western Madagascar. This 17,000 hectare forest is of significant ecological value and harbors a rich diversity of plants and animals.
We employ forest guards to reduce deforestation and poaching of lemurs.
What Lemur Species We Protect
We work in both east (Sahafina, near Brickaville) and west (Maintirano region) Madagascar protecting lemur species across both regions.
In the Benka conservation site, the program works to protect the following species:
One of our primary approaches to forest protection includes the use of conservation payments to local communities. This program ensures that communities receive direct material benefits in exchange for supporting ongoing conservation projects.
Biodiversity Conservation Madagascar also implements the following programs in partnership with local communities:
Eucalyptus and fruit tree plantations
To alleviate pressures on the forest, at BCM we manage the growing and planting of Eucalyptus trees, which provide a good source of fuel and construction materials for local communities. Eucalyptus trees, due to their ability to grow quickly and without a lot of water, are an ideal replacement for the precious and slow-growing hardwood trees that have been traditionally cut down by Malagasy communities. BCM has also helped plant fruit trees in local villages to provide a secondary source of food and income to the local people.
Water wells
BCM has provided the materials for local communities to build four water wells. This is of considerable importance as it helps assure a continuous water supply for the local community.
Agricultural training
BCM has trained local communities on how to effectively grow vegetables and to improve their rice growing techniques.
The Wildlife Conservation Society (WCS) saves wildlife and wild places worldwide through science, conservation action, education, and inspiring people to value nature. In Madagascar, we undertake conservation in and around the perimeter of the Marika National Park in the northeast of the country, where we partner with local communities to ensure lasting conservation success.
How We Protect Lemurs And Other Wildlife
Activities include a comprehensive field-based system of surveillance, law enforcement monitoring and ecological monitoring. We also work on restoration and maintenance of critical forestry corridors, research into habitats and species, and strengthening of the Government’s ability to manage and enforce forest and marine resource use regulations. WCS and our partners strive to develop the landscape as a model for resource conservation and biodiversity protection through better land stewardship linked to improved livelihoods.
Ecological monitoring of lemurs
We conduct ecological monitoring of lemurs annually at the Makira National Park in collaboration with the local communities. The aim is to detect any changes in the populations of 7 species. Data on lemur abundances, habitat health, and threats facing biodiversity are collected and analyzed to show the possible variations in lemur populations and help target conservation programming. In parallel with this ecological monitoring, WCS Madagascar collaborates with international and national researchers to enrich bio-ecological information on lemurs through various methods including surveys and genetic analysis. Lastly, in collaboration with GERP Association, we helped discover a new species of mouse lemur in 2009.
Participatory Conservation of Silky Sifaka (Propithecus candidus) in Makira Natural Park
Since 2005, in collaboration with international and national researchers, WCS has carried out extensive research on the Silky sifaka, a critically endangered lemur species in northeastern Madagascar. In addition to research, this program aims to:
Adopt a practical conservation action plan for the Silky Sifaka that is based upon participatory conservation measures
Use baseline data on Silky Sifaka abundance, distribution and threats to identify priority conservation actions for inclusion in a conservation action plan
Gain community and authority consensus on the conservation action plan
Develop and implement a synchronized ranger and community ecological monitoring network in Makira Natural Park
Develop and implement a community ecological monitoring network
This program will also have a community development component, which will involve education and awareness raising programs. In addition, we hope to integrate Silky sifaka conservation in community ecotourism activities that generate economic benefits for the local community. For example, the organization has developed an eco-lodge and partnerships with private tourism operators. The chance to observe the Silky Sifaka in the wild is a key attraction of the site for tourists so it provides a tangible opportunity to generate economic benefits for the community resulting from the conservation of this species.
What Lemur Species We Protect
It’s our aim to contribute to the protection of lemur species found in Makira National Park. This includes more than 15 species of lemurs known to inhabit it. Seven of them are included in WCS’ Makira Project conservation targets:
At WCS we work hard to ensure the sustainability of our programming, as there are clear links between improved livelihoods, improved land stewardships, and conservation. To achieve this, we engage with local communities to build their capacity as effective stewards of their natural resources. We ensure communities derive benefits from the natural resources through promotion of community-based ecotourism and nature based product enterprises, improved agriculture, reinforced governance, and market access.
Partnerships are established through the transfer of forest management to local communities. Communities are also involved in patrolling and ecological monitoring. In addition, we have trained dozens of local community teams to assist in data collection programs, thereby increasing the capacity of communities to monitor local biodiversity and ecosystems.
WCS is developing a network of community based natural resource management sites in the form of a ‘green belt’ around the protected areas. We provide support to communities to improve sustainable management of natural resources through diversification of livelihood options and activities to improve human health and welfare.
Finally, WCS is helping secure the area’s financial future, and has developed partnerships with the private sector in the sale of carbon credits from avoided deforestation, ecotourism, and wildlife friendly products.
Lemur Conservation Foundation
Biodiversity Conservation Madagascar (BCM) was established in 2002 as the conservation arm of Bioculture (Mauritius) Ltd. Our main goals are to conserve threatened forests in east and west Madagascar that are of high biodiversity value, especially those rich in lemur species. We currently work in the 2,400 hectare lowland rainforest in Sahafina (East Madagascar) and the Beanka dry deciduous forest in the Maintirano region (West Madagascar).
