Nakdong River - Ecology

Ecology

The Nakdong valley includes numerous floodplain wetlands, the most well-known of which are the Joonam Reservoirs near Changwon City and Upo Ramsar site, in Changnyeong County, South Gyeongsang. These wetlands, while significantly degraded and overdeveloped, still provide habitat to a significant number of rare and threatened species, most especially birds (such as the Baikal Teal, Anas formosa, and White-naped Crane, Grus vipio), fish and plants. Despite being home to the bustling Port of Busan, the Nakdong Estuary is also internationally important for waterbirds, despite recent ecologically-destructive developments including reclamation for housing and industry (e.g. the Busan New Port), the ongoing construction of a major bridge (the Miyeonji Bridge) and most recently the threatened construction of the Korean Grand Canal project.

The Nakdong and its tributaries also serve as a major source of drinking water for the inhabitants of the river basin and others nearby. However, water pollution due to domestic and agricultural wastewater remains a serious concern.
