Site description
The IBA comprises Sri Nan proposed national park, which borders Lao P.D.R. and is contiguous with Mae Jarim Wildlife Sanctuary (IBA TH009) to the south-east and Mae Jarim proposed national park (IBA TH010) to the north. The topography of the site is predominantly hilly. The site straddles the Lam Nam Nan river and contains the reservoir of Sirikit dam, which the river feeds. The principle habitat at the site is mixed deciduous forest, which covers over 70,000 ha. Deciduous dipterocarp forest predominates on the lower slopes, covering c. 13,600 ha, with some hill evergreen forest above 1,000 m asl and coniferous forest along ridges between 500 and 1,200 m asl.

Key biodiversity
Sri Nan is an important site for the globally threatened Green Peafowl Pavo muticus. Surveys between 1999 and 2002 estimated a population of less than 100 individuals, shared among Sri Nan and two contiguous IBAs: Mae Jarim Wildlife Sanctuary (TH009) and Mae Jarim proposed national park (TH010). Most birds occur at Sri Nan, on either side of the Nan river, from Huai Rahoy downstream to the Sirikit dam, between 100 and 600 m asl. The site also supports a significant population of the globally near-threatened Siamese Fireback Lophura diardi.
