Seagrass meadows are among the ocean’s most overlooked ecosystems — and Action For Ocean’s dedicated seagrass programme is now taking shape to protect them.
Seagrass meadows stabilise sediment, filter coastal waters, and provide feeding and nursery grounds for species ranging from juvenile fish to sea turtles. They also store carbon efficiently, making them a critical — if underappreciated — part of the blue carbon system. Along Tanzania’s coast, seagrass meadows face the same pressures as coral reefs and mangroves: coastal development, destructive fishing practices, and sedimentation.
Action For Ocean treats seagrass as inseparable from coral and mangrove recovery. Building on the same community-led model already proven through its coral and mangrove work, AFO’s dedicated seagrass programme is currently in development — extending habitat research and community-based monitoring to the third pillar of Tanzania’s critical marine habitats. As this programme takes shape, seagrass mapping and protection will become core to the same 2030 target that drives coral and mangrove work.
As it develops, AFO’s seagrass programme will contribute to the organisation’s 2030 target of 20 square kilometres of marine habitat restored across Tanzania’s coastline.
A reef without seagrass is a reef without its nursery.
Seagrass conservation is the protection and restoration of underwater seagrass meadows, which stabilise coastal sediment, filter water, and provide nursery habitat for marine life.
Seagrass meadows function as nurseries for many of the same fish species that live on coral reefs, and they help filter the water that reaches both reefs and mangrove forests — so their health directly affects the other two ecosystems.

Like coral reefs and mangroves, Tanzania’s seagrass meadows face pressure from coastal development, destructive fishing practices, and sedimentation.
