Site description
The IBA comprises Mae Yom National Park, which is contiguous with Doi Phu Nang proposed national park (IBA TH015) to the north. The site includes a substantial portion of the Mae Yom river valley. The dominant vegetation type at the site is mixed deciduous forest, while hill evergreen forest is found in the foothills, and deciduous dipterocarp forest occurs in the low-lying plains. One of the most notable features of the site is a 4,800 ha tract of natural Teak Tectona grandis forest; by far the largest (and also considered the richest) natural Teak forest remaining in Thailand. At least part of the site was formerly under a logging concession.

Key biodiversity
Mae Yom National Park is an important site for the conservation of the globally threatened Green Peafowl Pavo muticus. This species was formerly widespread along the Mae Yom river but disappeared due to hunting, logging and encroachment. Its rediscovery at the site, in March 1996, led to a wide-ranging survey for the species and other pheasants in northern Thailand, which located a population of over 200 individuals, shared between Mae Yom National Park and two other IBAs: Wiang Lor Wildlife Sanctuary and adjacent area to the east (TH014) and Doi Phu Nang (TH015). In addition, there is a record of the globally threatened Silver Oriole Oriolus mellianus from the site, and the globally near-threatened White-rumped Falcon Polihierax insignis also occurs.
