Red ruffed lemur (Varecia rubra). The IUCN Red List of Threatened Species 2020

Abstract

A population reduction ofgreater than or equal to 80% is suspected to be met over three generations (24 years, assuming a generation length of 8 years). This is based on a continuing decline of the population, due to unsustainable hunting pressure and a reduction in the extent and quality of habitat from subsistence and cash-crop agriculture, illegal logging for precious timber, and frequent cyclones. Based on suspected and inferred decline, measured direct and indirect threats, and its narrow niche dimensions, the species is listed as Critically Endangered.
