A large-scale forest fire occurred in the Daxinganling Mountain area in May, 1987. The burnt area extended up to 1.345 million hectares. An investigation was carried out on the effects of site preparation in the burnt area on the natural regeneration of tree species. Natural regeneration of Larix gmelinii Rupr. and Pinus sylvestris var. mongolica Litv. was facilitated by the site preparation after forest fires of light and intermediate intensity. Seedlings of Pinus sylvestris var. mongolica were very few irrespective of the fire severity. A large number of seedlings of Betula platyphylla was found in the heavy-fire site, which regenerated mainly from 1991 to 1993. The results suggest that the arrangement of mother trees play an important role in the recovery of forests after forests fires in the Daxinganling area.
