Indri indri
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Indri faces severe population decline primarily due to slash-and-burn agriculture and logging that fragments its rainforest habitat into increasingly isolated patches. Mining activities and charcoal production further degrade remaining forest areas, while the species' extremely slow reproductive rate—females give birth only every 2-3 years—makes population recovery exceptionally difficult. Cultural taboos that traditionally protected Indri are weakening in some regions, leading to occasional hunting pressure.
Habitat
Indri inhabit the primary and secondary rainforests of eastern Madagascar, preferring the upper canopy of montane and lowland tropical forests between 200-1,800 meters elevation. They require large territories of continuous forest cover due to their specialized diet of leaves from specific tree species and their territorial singing behavior.
