• Alaotra reed lemur (Hapalemur alaotrensis). The IUCN Red List of Threatened Species 2020

      Ralainasolo, F.B; Raveloarimalala, M.L; Randrianasolo, H.; Reuter, K.E; Heriniaina, R; Clarke, T; Ravaloharimanitra, M.; Volampeno, S.; Donati, G; Razafindramanana, J.; et al. (2020)
      Listed as Critically Endangered as the species has been observed to have undergone a population reduction of greater than or equal to 80% over a period of 27 years (three generations), due primarily to continuing decline in area, extent and quality of habitat, in addition to exploitation through unsustainable hunting pressure. These causes have not ceased, and will to a large extent not be easily reversible.
    • Black lemur (Eulemur macaco). The IUCN Red List of Threatened Species 2020

      Andriantsimanarilafy, R.R; Borgerson, C.; Clarke, T; Colquhoun, I.C; Cotton, A; Donati, G; Eppley, Timothy M.; Heriniaina, R; Irwin, M; Johnson, S; et al. (2020)
      The range of the species is severely fragmented and remaining areas of forest are under anthropogenic pressure (Mittermeier et al. 2010, Tinsman et al. 2019). Given this, and that the overall population size is suspected to be in decline at a rate of >50% over three generations, the current assessment lists Eulemur macaco as Endangered.
    • Mongoose lemur (Eulemur mongoz). The IUCN Red List of Threatened Species 2020

      Razafindramanana, J.; Eppley, Timothy M.; Rakotondrabe, R.; Roullet, D.; Irwin, M; King, T. (2020)
      There is a suspected population reduction of greater than or equal to 80% in this species over a three generation period (estimating the generation length to be 8 years). This time period includes both the past and the future. Causes of this reduction (which have not ceased) include continuing decline in area (through deforestation), extent and quality of habitat (selective logging), and exploitation through unsustainable levels of hunting. Furthermore, Eulemur mongoz has undergone hybridization with E. rufus in Western Betsiboka. Based on these premises, the species is listed as Critically Endangered.
    • White-fronted lemur (Eulemur albifrons). The IUCN Red List of Threatened Species 2020

      Borgerson, C.; Eppley, Timothy M.; Donati, G; Colquhoun, I.C; Irwin, M; Johnson, S; Louis, E.E.; Patel, E.; Ralainasolo, F.B; Ravaloharimanitra, M.; et al. (2020)
      Listed as Vulnerable, Eulemur albifrons is suspected to have undergone a population decline greater than or equal to 30% over a period of 24 years (three generations), due primarily to unsustainable hunting pressure and continuing decline in area, extent and quality of habitat. These causes have not ceased, and will, to a large extent, not be easily reversible
