jeopardize the species' existence. Burning of the remaining marshlands is a common practice for fishing and cattle grazing, leading to increased aquatic plants that choke fishing areas. This cycle of burning not only poses a direct threat to the lemurs but also limits marsh regeneration after flooding, exacerbating the challenges faced by the
Hapalemur alaotrensis population. Hunting for food and capturing lemurs for pets have significantly contributed to the decline in Hapalemur alaotrensis numbers. Local communities employ various hunting and trapping methods, including direct pursuit by dogs, harpooning, snares, and habitat burning. With over 1,000 lemurs hunted annually in certain years, anthropogenic pressures remain a considerable threat to the species' survival.

Conversion of the marsh habitat to rice fields poses a severe threat to the survival of the
Hapalemur alaotrensis species. While the remaining marshlands are resistant to conversion due to regular flooding, the potential implementation of a major drainage project in the region could significantly
