At each time of six censuses, fifty quadrats (1m×1m) were set in a burnt site which had been abandoned after a forest reclamation and subjected to major human impacts such as cutting and burning. In August 1997, three months after a severe wildfire that burnt almost all of living plants and peat to about. 25 cm in depth from the ground surface, dense seedlings of Melaleuca cajuputi POWELL (mean±SE=52.7±6.3 indivs./m^2) emerged from the wind-dispersed seeds. Clones of such herbaceous plants as Blechnum indicum BURM. f. (mean±SE=0.7±0.2 clones/m^2) and Lepironia articulata (RETZ.) DOMIN. (mean±SE=0.2±0.1 clones/m^2) also regenerated sparsely from the survived subterranean fragments. Until August 2000, the mean (±SE) height and coverage of vegetation increased sharply (29.0±7.7-187.4±5.1 cm and 4.1±1.1-77.0±2.2%, respectively), especially around the rainy seasons, although species composition didn't show clear change (range of mean species density=1.5-2.8 spp./m^2). Such a recovery pattern was greatly affected by the population development of M. cajuputi: i.e., the mean (±SE) maximum height and the mode of the frequency distribution of cover class of the BRAUN-BLANQUET scale for M. cajuputi increased 9.1±2.1-179.8±6.0 cm and 1-4, respectively, and the high density differed scarcely (33.1±3.6-73.8±12.5 indivs./m^2) for three years. Consequently, a cohort of M. cajuputi germinated simultaneously, overcame other species within 1.5 years and succeeded in the reconstruction of Melaleuca-dominant scrub.}, pages = {81--87}, title = {Drastic recovery of Melaleuca-dominant scrub after a severe wild fire : A three-year period study in a degraded peat swamp, Thailand}, volume = {7}, year = {2000} }
