[Relevance description]
To improve our understanding of lemur distributions, densities, and population size in southeastern Madagascar
At Tsinjoarivo, I conduct research under the banner of TFFP (Tsinjoarivo Forest Fragments Project) with my Malagasy collaborator Mr. Jean-Luc Raharison. We are working on establishing a not-for-profit legal entity “Sadabe” to co-ordinate the education and conservation activities at Tsinjoarivo.
Project summary
The aims of this project were to:
(1) use satellite imagery and GIS to create a model of forest habitat in southeastern Madagascar
(2) collect and compile primate census data from the same region
(3) use census data to more precisely define geographic ranges of diurnal and cathemeral primate species
(4) use the combined dataset to estimate average population density and overall population size.
1. Investigate the effects of habitat loss and fragmentation on sifaka ecology and behaviour at Tsinjoarivo.
2. Promote conservation at Tsinjoarivo through environmental education and sponsoring reforestation projects.
3. Promote community and individual health at Mahatsinjo through investing in education and health initiatives (in collaboration with Madagascar Ankizy Fund, www.ankizy.org).
Start date: 1995
Duration: 10 years
