[7] The tail and body of the Lac Alaotra bamboo lemur are both 40 cm (16 in) on average, and it weighs 1.1–1.4 kg (2.4–3.1 lb), with males slightly larger than females.

[9] The population of Lac Alaotra bamboo lemur is declining as suitable habitat around the lake is being destroyed and converted to rice fields.

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 jeopardize the species' existence.

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.

Local communities employ various hunting and trapping methods, including direct pursuit by dogs, harpooning, snares, and habitat burning.
