Bagan Lalang sits along the coastline near the mouth of Sungai Sepang, where coastal waters meet a stretch of mangrove ecosystems that support both biodiversity and coastal protection. These mangroves act as natural buffers against erosion while also serving as breeding and nursery grounds for marine life.
Aside from being helmed as Sepang’s eco-tourism hotspot, this region is also home to a local fishing community that depends on these waters for daily income. Small-scale fishermen operate along the coast and river mouth, making the health of the shoreline and mangroves directly tied to their livelihoods. Waste accumulation — whether from visitors or carried downstream via Sungai Sepang — can affect catch quality, damage nets, and disrupt the ecosystem they rely on.
