Xylocarpus granatum belongs to the family Meliaceae and is widely distributed across tropical coastal regions, including South Asia, Southeast Asia, East Africa, and the Pacific Islands. It thrives in mangrove forests, particularly in areas with soft, muddy substrates and tidal influence. The species is easily recognized by its distinctive large, spherical fruits, which resemble cannonballs—hence its common name.

A lagoon is a shallow body of water that is partly or completely separated from the sea by obstacles like sand barriers, coral reefs, barrier islands or mangrove belts. Lagoons can be a huge biodiversity hotspot that includes various floral and faunal species. Some of them are mangroves, seagrasses, algae, planktons, fishes, crustateans, molluscs, birds and other fauna like plychaetes and crocodles. As a island country consisting of 14 coastal districts, Sri Lanka provides home for a plenty of lagoons- ex: Chillaw lagoon, Negombo lagoon, Batticolo lagoon, Koggala lagoon, Rekawa lagoon and etc…

Mangrove-associated fisheries play a vital role in the livelihood and food security of coastal communities living around lagoon ecosystems. The complex root systems of mangrove trees provide shelter, feeding grounds, and nursery habitats for a wide range of aquatic species, including fish, crabs, and shrimp, making mangrove areas highly productive fishing zones. In the lagoon environment, fishers harvest a variety of species using traditional and small-scale methods such noodling, traps, kemana, and brush-pile-based techniques. Juvenile and adult fish use the submerged mangrove roots for protection from predators and as feeding grounds, making these areas important locations for artisanal fish catches. Crabs, especially mangrove and lagoon crab species, thrive among prop roots where they feed, hide, and molt. During low tide, many are caught by hand or using simple traps placed near root clusters. Similarly, shrimp species rely on mangrove detritus and nutrient-rich waters for growth. Their abundance in channels and root zones supports seasonal shrimp collection using nets and traditional gear. Overall, mangrove-associated fishing forms a tightly linked socio-ecological system where the health of the mangrove habitat directly influences the availability of lagoon fish, crabs, and shrimp. Protecting mangroves ensures the sustainability of these fisheries while supporting the cultural traditions and livelihoods of lagoon-dependent communities.

Mangroves are powerful natural carbon sinks, capturing and storing atmospheric carbon in their biomass and soils. The Chilaw Lagoon mangrove ecosystem holds immense untapped potential as a natural carbon sink. Through the evaluation of aboveground, belowground, and sediment carbon stores, this study provides important new insights into the lagoon's potential to mitigate climate change. The results of this study may support conservation and restoration initiatives while highlighting the ecological and economic significance of mangroves. In order to improve climate resilience plans and encourage sustainable ecosystem management in coastal communities, this study provides baseline data to stakeholders and policymakers.

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. 🔹 A Natural Reef System Barnacles, oysters, mussels, and worms settle on mangrove prop roots, turning them into miniature reefs. These layered surfaces provide safe havens for crabs, shrimps, juvenile fish, and countless small creatures. 🔹 Ecosystem Engineers Sessile filter feeders like oysters and barnacles clean the water by removing suspended particles, while crabs and mollusks recycle nutrients by breaking down fallen leaves. Together, they stabilize sediments, trap carbon, and protect shorelines. 🔹 Balancing the Food Web Root-dwelling species not only feed on algae and detritus but also serve as prey for birds and larger fish. This delicate balance maintains the health and productivity of the lagoon. 🔹 Foundation Species Oysters and mussels act as “foundation species” – creating structures that allow other organisms to settle, grow, and flourish. Their presence transforms simple roots into complex, multi-layered habitats. 🔹 Three Unique Study Sites Researchers explored three areas of the lagoon: Open Lagoon – brackish waters with slower flow, rich in sediments. Bata Canal – lined with 1995 mangrove plantations, offering diverse habitats. Dutch Canal – with stronger tidal exchange and higher salinity, creating distinct settlement patterns. 🐚 From camouflaged crabs and black tiger shrimp hiding among roots, to oysters building reefs that support countless others, the mangrove root zone is a bustling underwater city. These hidden ecosystems remind us that conserving mangroves means protecting not just trees, but the entire web of life they support. 🌊🌿

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.

Due to their buoyancy, plastics travel long distances by wind, tides, and currents—reaching even remote islands and deep-sea areas. Events like floods and hurricanes further push land-based debris into the sea. Ocean currents gather these plastics into vast “garbage patches”.

Studies have found that 80% of the plastics are...

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.

The recent heavy rains over Pambala Lagoon have transformed the serene waters into a mesmerizing natural spectacle. The rising floodwaters have created an unexpected phenomenon – crabs climbing onto tree trunks! While these crustaceans are typically known for scuttling along the muddy banks and shallow waters, the sudden inundation has pushed them to seek refuge above ground. It’s incredible to witness their adaptability and survival instincts as they climb mangrove trunks, showcasing their determination to weather the storm.
