Site details
Site description: The IBA comprises Nanthaburi proposed national park. The site lies adjacent to the international border with Lao P.D.R. and adjoins two other IBAs: Doi Phu Nang (TH015) and Doi Pha Chang Wildlife Sanctuary (TH013). The eastern flank of the site is enclosed by the Nan-Tung Chang highway. The topography of the site is generally hilly or mountainous; Doi Waw, the highest peak, is located in the south-west. Mixed deciduous forest is the dominant forest type at lower elevations, covering c.44,000 ha of the site, while hill evergreen forest is found on the higher peaks and along ridges, covering c.30,950 ha. There are also small patches of semi-evergreen forest and deciduous dipterocarp forest at the site. Permanent and shifting cultivation cover a further c.10,660 ha.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas) The site has been reviewed and re-confirmed as a KBA in the process of compiling the revised 2011 CEPF Ecosystem Profile for the Indo-Burma Hotspot.
Additional biodiversity: The site is important for the conservation of the globally threatened Green Peafowl Pavo muticus. One other globally threatened species has been confirmed at the site, Grey-sided Thrush Turdus feae, which is a winter visitor. There is also an unconfirmed record of a third globally threatened species: Imperial Eagle Aquila heliaca. The site qualifies under criterion A3 because it supports seven species restricted to the Sino-Himalayan Temperate Forests (Biome 07) and 36 species restricted to the Sino-Himalayan Subtropical Forests (Biome 08) Non-bird biodiversity: Plants Dipterocarpus turbinatus (CR) Afzelia xylocarpa (EN) Hopea ferrea (EN)
