IPCC recognizes seagrass beds, salt marshes, and mangroves as the three primary blue carbon ecosystems. Taean National Park features a diverse coastal environment including salt marshes, coastal sand dunes, and seagrass beds. These habitats support a variety of species that are specially adapted to these environments. These areas are ecologically significant both as critical habitats and natural carbon sinks. However, ongoing coastal development and increasing visitors have led to continuous degradation and a reduction in their area due to human activities.
In the past, fishery by-products were classified as general waste. Improper disposal practices, including illegal dumping and uncontrolled accumulation along the coast, resulted in marine pollution, foul odors and decay. To address this issue, legislation was enacted to promote the recycling of fishery by-products. In line with this initiative, the park launched a pilot project to restore salt marshes and reinforce the coastline using recycled oyster shells.
