• Betsileo woolly lemur (Avahi betsileo). The IUCN Red List of Threatened Species.

      Eppley, Timothy M.; Patel, E. (2020)
      The extent of occurrence of this species covers less than 1,470 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. Based on these premises, the species is listed as Endangered.
    • Crowned sifaka (Propithecus coronatus). The IUCN Red List of Threatened Species 2020

      Razafindramanana, J.; Salmona, J.; King, T.; Roullet, D.; Eppley, Timothy M.; Sgarlata, G.M.; Schwitzer, C. (2020)
      Listed as Critically Endangered as the species is suspected to have undergone a population decline of greater than or equal to 80% over a period of 30 years (three generations), due primarily to observed continuing decline in area, extent and quality of habitat from burning of forests to provide pasture for livestock and logging for charcoal production, in addition to exploitation through unsustainable hunting pressure. These causes have not ceased, and will to a large extent not be easily reversible. Given the likely continuing population decline, the species has been uplisted to Critically Endangered.
    • Lorenz Von Liburnau's woolly lemur (Avahi occidentalis). The IUCN Red List of Threatened Species 2020

      Eppley, Timothy M.; Patel, E.; Reuter, K.E; Steffens, T.S. (2020)
      The species is distributed in two disjunct ranges which, calculated separately, sum up to 3,057 km2; the minimum convex polygon of the total range measures 8,619 km2. This extent of occurrence (EOO) is severely fragmented and undergoing continuing decline in area, extent and quality of habitat with no overall improvement. It has been estimated that there will be a 78% reduction in the species' range from 2000 to 2080 due to climate change (Brown and Yoder 2015). Based on the EOO, the species is listed as Vulnerable.
    • Ramantsoavanaa's southern woolly lemur (Avahi ramanantsoavani). The IUCN Red List of Threatened Species 2020

      Eppley, Timothy M.; Patel, E.; Andriamisedra, T.R; Ranaivoarisoa, F.N.; Peterson, C.R.; Ratsimbazafy, J.; Louis, E.E. (2020)
      The extent of occurrence of this species covers approximately 14,376 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. The number of mature individuals is also thought to be in decline. Based on these premises, the species is listed as Vulnerable.
