Koshi Conservation Center (KCC) is NTNC's eight and most recent project under operation. It was set up as independent project officially from September 2021. Prior to that, the Trust's Koshi-related operations were managed from its Biodiversity Conservation Center (NTNC-BCC) office in Sauraha, Chitwan. A dedicated project focusing on Koshi Tappu region now ensures NTNC's physical presence across all the protected areas in the Tarai region of Nepal, extending much necessary conservation support into eastern Nepal, where human-elephant conflict are the severest in the country. The project is meant to support the Department of National Parks and Wildlife Conservation (DNPWC) and local communities enhance the conservation value of Koshi Tappu Wildlife Reserve (KTWR)—a 175 square kilometre protected area situated in the Saptakoshi River plain of south-eastern Nepal that serves as a prime habitat for diverse wildlife and wetland ecosystems.
The reserve (KTWR) is home to Nepal's last remaining herd of the wild water buffalo (Bubalus arnee) and serves as a vibrant habitat for other threatened fauna like the Bengal florican (Houbaropsis bengalensis), Gangetic dolphin (Platanista gangetica) and Fishing cat (Prionailurus viverrinus). It is the first Ramsar site of Nepal and is also designated as an Important Bird and Biodiversity Area (IBA). The reserve falls within the traditional route of elephants moving between India and eastern Nepal, due to which human-elephant conflicts in this region are intense.
Some of the priority areas of the Koshi Conservation Center (NTNC-KCC) include supporting park/reserve authorities and local communities in reducing eastern Nepal's human-elephant conflict, creating specialized wildlife rescue and problem animal management capacities, conducting wildlife research and monitoring the reserve's "threatened" fauna like Arna, Bengal florican, Gangetic dolphin, Fishing cat, including winter water birds and aquatic fauna, grassland and other habitat management initiatives, this along with expanding opportunities for local livelihoods and building community engagement in wildlife conservation.
