The mangrove ecosystems of the Pambala–Chilaw Lagoon are more than just forests by the sea – they are living laboratories of biodiversity. Beneath the tangled web of Rhizophora mucronata roots, an entire community of organisms thrives, playing vital roles in keeping these ecosystems healthy. biodiversity

Tropical mangroves are rich in carbon and play an important role in reducing climate change by storing carbon dioxide in their trees and soils. However, in Sri Lanka, little research has been done on how restored mangroves contribute to carbon storage.
This study looks at mangrove restoration and afforestation efforts in the Chilaw lagoon, which began in 1994 with the planting of Rhizophora mucronata and R. apiculata. Research was carried out in a 25-year-old mangrove plantation covering about 0.25 hectares. We identified the species present, measured tree height and girth, and estimated above- and below-ground biomass and organic carbon using standard methods and equations. Carbon sequestration
Giant Mud Crab- Scylla Serrata
The larvae develop in the marine environment until they reach the juvenile stage, at which
point these juvenile crabs migrate from the ocean to mangroves, brackish waters, estuarine
regions, or lagoon areas. Subsequently, these juvenile crabs mature into adult crabs within
the mangroves, brackish waters, estuarine regions, or lagoon areas. Intertidal mangrove
forests are essential as they provide food, shelter, nursery habitats, and refuge for juvenile
S. serrata. The intricate root systems, such as the prop roots of Rhizophora sp. species,
create hiding spots for these juvenile crabs, protecting them from predators. The mangrove
environment offers safety during their molting phase, a time when crabs are particularly
vulnerable, and it maintains stable conditions—such as reduced water turbulence,
consistent water temperatures shielded by mangrove trees, and suitable salinity levels—
that are conducive to their growth.

Studies have found that 80% of the plastics are land-based. Plastics from landfill enter into the ocean through poor management and improper disposal of sewages and plastic wastes, costal landfill operations and litter carried through streams and rivers 9. Other sources include accidental spillage during handling and other processes 5.
Remaining 20% are the litters generated by ships/boats through recreational activities, discharge of marine litters 9, nautical activities, fishing activities and aquaculture 4. Of which commercial fishing accounts for most of the impacts. This includes discarded fishing items, together with monofilament liens and nylon netting

Monkeys, though not traditionally considered primary pollinators like bees or butterflies, can play a role in pollination, particularly in tropical and subtropical ecosystems. This process is known as therophily, which refers to pollination by non-flying mammals.

On December 18, 2024, the Lanka Mangrove Museum had the honor of welcoming a research student from the University of North Carolina at Chapel Hill, United States. Her research focuses on one of the most vital contributions of mangrove ecosystems to the environment — carbon sequestration. Her visit highlights the museum’s ongoing commitment to supporting research and fostering global collaboration in the field of mangrove conservation.
