Funds are needed for two silky sifaka conservation research projects: Arboreal camera trapping and Long-term monitoring. From December 1, 2023 to June 1, 2024, we plan to conduct a lemur survey in southwestern Anjanaharibe-Sud (near Camp Indri) using motion-activated camera traps placed high in the trees and on the ground.  Particularly for very rare species, such as critically endangered silky sifakas, or cryptic species like aye aye, traditional survey methods such as line-transect surveying, require large amounts of time and resources and do not always produce clear results. Arboreal camera trapping is a new methodology increasingly used for lemurs in Madagascar. For more information about the project, check out our full Arboreal Camera Trapping Silky Sifaka proposal.

Our long-term monitoring program focuses on four groups of silky sifakas that we would like to visit each year (Camp Marojejia in Marojejy National Park, Camp Indri in Anjanaharibe-Sud Special Reserve, and Maherivaratra, a disturbed unprotected forest).  Additionally, we hope to start visiting the groups near Simpona Lodge in Makira National Park, an unusual low-elevation site.  We have habituated several of these groups and have established individual recognition.  It is critical to regularly follow these groups (at least once per year for several weeks) to learn more about their demography and document critical life-history parameters such as number of infants born each year, birthdates, changes in group membership as well as obtaining ranging and feeding data.  Moreover, our team plays a vital role in protecting these groups by destroying bushmeat traps, identifying new disturbances in their habitat, and organizing patrols if needed.  Our presence deters poaching.
