Red-bellied lemurs are classified by the International Union for the Conservation of Nature (IUCN) as Vulnerable. Their greatest threats are rainforest destruction, hunting, and the live animal trade. Habitat destruction has led to declining reproductive rates, contributing to the lemurs' declining population. They are also vulnerable to climate change, which appears to be driving populations to higher altitudes.

LemurID harnesses facial recognition tools to identify individual red-bellied lemurs throughout Eastern Madagascar, allowing researchers and conservationists to observe and track them noninvasively across space and time. This technology will allow red-bellied lemur populations to be monitored for changes over time and in the face of ongoing threats. An important aspect of LemurID is that it is available to the public, enhancing the experiences of those who observe lemurs while allowing them to contribute to lemur conservation.
