Critically Endangered Lemurs Experience Slight Recovery in 2021, But Forest Loss Continues

Conservation efforts in Madagascar’s forests have led to a small rise in the numbers of two Critically-Endangered lemurs. Hailed as a success of the year, the International Union for the Conservation of Nature (IUCN) also celebrated the increase in numbers of another lemur species in the same area, totaling 48 new individuals.

Representing a rounding error in terms of Earth’s total landmass, Madagascar nevertheless commands incredible attention due to its biodiversity. Yet despite this, poverty and weak governance cause masses of forests to be lost every year, depriving the island’s iconic lemur species of their habitat.

According to Global Forest Watch, the forest around the Maevatanana-Ambato-Boeny Wetlands has lost 17% of its initial cover over the past 20 years. Fire, illegal logging, and the conversion of forests into agricultural areas or pastures for livestock are the known causes of this degradation.

These wetlands run through the Ankarafantsika National Park, one of the country’s richest and most successfully-managed dry forests, and home to multiple lemur species; including an estimated 47,000 Conqueral’s sifakas. Deforestation has been increasing in the park since the 2009 coup d’état, notably this year when two fires scorched about 35 square miles (90 square kilometers), or around 6.6% of the park’s total area.

Before 2009 the forest had remained largely undisturbed since its creation in 1920, reports Mongabay. Now the IUCN, The Aspinall Foundation, and the Missouri Botanic Garden’s programs in Madagascar are trying to target fires, which are often set accidentally by locals, as a way of saving both the forests and their lemurs; and they have some heartening news to report.

Lemur patrol

The IUCN’s Save Our Species Africa program began outreach operations in communities surrounding the wetlands, where fire is actually permitted sometimes, but like so for many citizens of the world, the laws of their government are not all clearly understood.

Furthermore, Mongabay reports, many locals will use fires as a way of protesting government corruption. These protest fires can quickly get out of hand and decimate large areas of the park.

“As forest connectivity in the area is already critical, conserving it, and trying to extend it is extremely necessary,” IUCN writes. “Thus, the project’s mission is to raise awareness about these laws and regulations, to prevent accidents from happening and to let people know when and where fires are allowed”.

“Increased patrolling efforts have resulted into an increase of lemur groups identified in the area. In fact, [an area] of monitored Crowned Sifakas has increased from 69 groups to 90 groups [of animals], of Mongoose Lemurs from 18 to 23 groups, and Red Brown Lemur from 20 to 22 groups. The project’s team also recorded births of 27 crowned sifaka, 8 mongoose lemurs and 11 red brown lemurs,” they conclude.

An additional outreach attempt involved finding jobs for vulnerable members of the communities living near prime lemur habitat, such as the elderly or unemployed. While the initial goal was to provide temporary employment to 300 people, the project ended up employing 2,513 community members.

Some of this was temporary work in reforestation efforts near Ankarafantsika. In six months, the project members, trained and organized by the Missouri Botanic Garden, produced 24,234 native plants from seven species in total at their tree nursery and have transplanted 14,536 trees in the reforestation area.
