Littoral forests are one of the most threatened ecosystems in Madagascar—an island country where almost all ecosystems are at serious risk. These forests once probably formed a long unbroken band along the southeastern coast, but they have been fragmented by fire, slash-and-burn agriculture, logging, and mining. An estimated 90% of littoral forest cover has been lost.
The Sainte Luce Littoral Forest (SLLF), in southeastern Madagascar, is one of those damaged forests, and its loss imperils the area’s extraordinary biodiversity. In the SLLF, 98% of the plant species are endemic to Madagascar; at least 42 plant species and 14 invertebrate species are endemic to the region. The SLFF is home to four endangered lemur species. There are other critically endangered species, including a gecko, an arboreal frog, a palm, and a tree on the very brink of extinction. It is entirely possible that many species in the area could be lost before we even learn of their existence.
SEED Madagascar has a multiyear plan to save the Sainte Luce forest, which covers 2,825 acres but has been carved into 17 fragments. This project, a standalone part of that larger effort, would create a reforested corridor uniting fragments of the original forest. SEED has already created four similar corridors. Because many species cannot cross the dry and sparsely vegetated gaps between the fragments, these small corridors play an outsize role in maintaining populations.
To create the corridor, local people are planting acacia seedlings, rapidly growing trees that create the right soil and shade conditions for reestablishing native plants later. A firebreak on either side of the forest corridor protects it from wildfire, a constant danger in the dry southeast. The corridor is protected by local law (dina) and a community forest patrol oversees enforcement.
Members of the Sainte Luce and Ebakika communities are receiving education and training, concentrating on fire prevention. SEED will also provide simple tools, such as locally made fire beaters—basically, poles with rubber flaps, which are used to fight fires. These benefits may seem small, but fire is an existential threat to the local people, 90% of whom are subsistence farmers or fishers and live below the international poverty line.
Seacology has partnered with SEED, whose staff members have worked in the Sainte Luce community for more than 20 years, on other successful projects in Madagascar.
Seacology made this grant in memory of Edward O. Wilson, the eminent evolutionary biologist who documented how habitat fragmentation causes species loss. Dr. Wilson served on Seacology’s Scientific Advisory Board until his death in December 2021.
