Site description The IBA encompasses the whole of Mae Jarim Wildlife Sanctuary, which lies along the ridge that divides Uttaradit and Nan provinces. The topography of the site includes both steep mountainous terrain and gently rolling hills. The site is contiguous with Sri Nan proposed national park (IBA TH008) to the north-west. The damper areas in the north of the site support moist evergreen forest, while the central ridge supports dry evergreen forest. Mixed deciduous forest is the dominant forest type in the centre and south of the site, and some deciduous dipterocarp forest also occurs.

Key Biodiversity Together with Mae Jarim (IBA TH010) and Sri Nan (IBA TH008) proposed national parks, Mae Jarim Wildlife Sanctuary supports a significant population of the globally threatened Green Peafowl Pavo muticus. This population is estimated at under 100 birds, most of which are considered to occur at Sri Nan, while Mae Jarim Wildlife Sanctuary supports a relatively small number.

Non-bird biodiversity: No information is available about other globally threatened species at the site.
