The 'water-grassland' is a result of aquatic plants forming a thick root mat that floats above the water, causing the ground to bounce underfoot.
The area is home to the Alocasia macrorrhizos, commonly known as giant elephant ear, which thrives in the high-humidity, swampy environment.
It acts as a vital catchment area for the local watershed, contributing to the irrigation systems of the nearby Dongyuan village.
The park provides a specific habitat for the endemic Taiwan lily, which blooms seasonally in the meadows.
The forest composition includes significant patches of established camphor and acacia trees that were historically managed for local industry.
Dongyuan Forest Recreation Area is primarily defined by its rare 'water-grassland' (shui-shang-cao-yuan), a unique ecological phenomenon where vegetation floats atop a peat bog. Located in the Mudan Township of Pingtung County, the area sits at an elevation of approximately 300 meters. The landscape consists of a mix of ginger lily fields, dense camphor forests, and marshland habitats. It serves as a protected environment for various local flora and the endangered Taiwan lily. The park is managed in coordination with local indigenous Paiwan community efforts to preserve the watershed. Elevated wooden walkways traverse the wetland sections to minimize human impact on the delicate root systems. The climate is notably cooler than the surrounding lowlands due to its forest canopy and elevation.
The wooden boardwalk overlooking the central water-grassland area.
Wear waterproof, non-slip footwear as the ground near the wetland can be permanently muddy.
Use insect repellent, as the humid, marshy environment supports a high density of mosquitoes.
Stay strictly on the designated wooden boardwalks to protect the unstable peat bog surface.
Do not attempt to walk directly onto the marshy 'water-grassland' area, as it is fragile and dangerous.
Requires advance reservation for entry as it is managed by the local tribal community.
Maintain silence to observe local birdlife; do not step off the boardwalks into the peat bog.
