Mangrove Restoration at Le Morne

Mangroves are indispensable to coastal ecosystems, serving as natural barriers against erosion, storm surges, and rising sea levels. They play a critical role in enhancing marine biodiversity by providing nurseries for juvenile fish and habitats for diverse species, while also acting as carbon sinks, mitigating the impacts of climate change. In Mauritius, the primary mangrove species are the Red Mangrove (Rhizophora mucronata), which dominates the ecosystem, and the Black Mangrove (Bruguiera gymnorrhiza). These species thrive in swamps, estuaries, and along the island’s coastline, contributing significantly to the health and resilience of coastal ecosystems. Recognising the urgent need for mangrove restoration, CGC launched a mangrove planting initiative at Trou Chenille, located in the Le Morne region. This area, part of the buffer zone of the Le Morne Cultural Landscape, holds exceptional ecological and cultural significance as a UNESCO World Heritage Site. However, it faces multiple threats, including habitat degradation, marine erosion, pollution, and human disturbances. In November 2024, CGC obtained the necessary permits to commence mangrove restoration works at Trou Chenille. The project will begin with the planting of 160 Rhizophora mucronata propagules along a 175-meter stretch of the designated plantation area. This species was selected for its ecological robustness and adaptability to coastal environments. Future plans include establishing additional mangrove plantations, strategically located in shallow waters parallel to the Trou Chenille track, which is currently experiencing significant marine erosion. Each plantation will span 1,000 meters in length and 50 meters in width, contributing to the restoration of the lagoon’s ecological balance. CGC’s approach integrates scientific expertise with community involvement to create a replicable model for mangrove restoration. By engaging local communities, CGC fosters awareness and ensures sustainable development while restoring the ecological integrity of Trou Chenille. This initiative reflects CGC’s commitment to balancing environmental conservation with socio-economic benefits, ensuring that natural resources are preserved for future generations.
