Stung Treng province, which covers an area of 11,092 square kilometers borders
Laos to the north,
Ratanakiri to the east,
Preah Vihear to the west and
Kratié and
Kampong Thom to the south. . Extensive forests, intersecting rivers and streams characterize it. Stung Treng includes also the western chunk of the massive
Virachey National Park, accessible from
Siem Pang. The province also includes
Veun Sai-Siem Pang National Park. The province also features three big rivers—the Sekong River, the Sesan River and the Mekong—with its hundreds of small islands scattered on the river stretch in
Stung Treng. A registered
REDD+ project under Japan’s
Joint Crediting Mechanism has operated in the
Prey Lang Wildlife Sanctuary landscape (including areas linked to Stung Treng), with
Conservation International Cambodia described in regional lessons-learned work as a coordinator of the project alongside government and private-sector participants. Until February 2022, it was one of the few provinces where you could see the rare and endangered
Irrawaddy dolphin in the wild near the Laos border,
Borei O’Svay Sen Chey District and Anlong Cheuteal in Stung Treng. The population has likely vanished due to
illegal fishing in the area. ==Climate==
