This brief outlines the mangrove ecosystems of the Rivière du Rempart district, a critical north-eastern region of Mauritius where coastal conservation and community action have led to some of the most resilient mangrove stands on the island.
The District of Rivière du Rempart is a cornerstone of the island's coastal protection, featuring a complex network of sheltered lagoons, barachois systems, and islet national parks. The region is predominantly dominated by the resilient Rhizophora mucronata species, which forms dense, arching root systems essential for filtering sediment and protecting the northern coral reefs.
Ecological Buffer: The mangroves here act as a vital filter for urban and agricultural runoff before it reaches the fragile marine ecosystems.
Species Diversity: While Rhizophora mucronata is the dominant pure stand, the region serves as a primary site for ongoing research into biodiversity and species recovery.
Conservation Focus: The district hosts Voluntary Marine Conservation Areas (VMCAs) and community-led replanting sites, highlighting its status as a leader in coastal resilience.
