Beimen Lagoon Introduction
The ecological environment of Beimen District belongs to the lagoon ecosystem, rich in fish, shrimp, shellfish, and mangrove landscapes. It is commonly home to many herons, waterfowl, mudskippers, and various crabs, showcasing the charm of lagoon ecotourism. Most notably, from October to April each year, the Black-bellied Tern visits this area. At dusk, flocks of Black-bellied Terns gather and fly in the sky, changing their formations according to the wind direction, creating a spectacular sight. The Avicennia marina mangrove used to grow abundantly in the marshland of Beimen Lagoon west of the Beimen oyster farm, but later it was developed into reclaimed land or converted into fish ponds, where many oyster racks can often be seen in the lagoon, forming another unique coastal landscape. Under the Tainan government's policy of actively restoring mangroves, a 6-hectare area of Avicennia marina has grown at the mouth of the Toubin River on the south side of the lagoon. In the Beimen Lagoon area, where the mouth of the Jushui River has more sediment, Avicennia marina has also been regenerated, and water hyacinth has been introduced for planting. Mangrove protection zones have been established at these two locations, dazzling visitors with their lush ecological scenery.
