An ecological assessment of lowland deciduous dipterocarp-oak, seasonal, hardwood forest on the base of the east side of Doi Sutep-Pui, Chiang Mai province, was conducted. Seven selected sites representing the most intact condition to the worst one were surveyed. Plant species diversity and abundance declined as fire damage increased. Details on the number of species, their habits, size classes of trees, pioneer vs climax species, woody seedlings, coppices, and herbaceous ground flora are presented. Species lists for all these categories and their abundance are also included. Profile diagrams and photographs of some sites are shown. The conservation value of lowland forests has been largely neglected and now many places require reforestation. The degree of degradation is serious and will continue to deteriorate unless effective protective and remedial action is done
