Because of these threats and their declining numbers, the International Union for Conservation of Nature (IUCN) considers lemurs to be the world's most endangered mammals, noting that as of 2013 up to 90% of all lemur species face extinction within the next 20 to 25 years.
På grund af disse trusler og det faldende antal lemurer betragter organisationen International Union for Conservation of Nature (IUCN) lemurer for verdens mest truede pattedyr og angav i 2013, at 90 % af alle lemur-arter står over for udryddelse i løbet af de næste 20-25 år.
