| Research Abstract |
Although it becomes high air temperature according to the amount of fuel, an underground temperature did not rise. It became clear that the species composition of vegetation changes according to the management history of a grassland in Mt. Kanpu. When management including grassland burning was carried out by high frequency, some grassland species of Erigeron thunbergii, Prunella vulgaris subsp. asiatica, Polygala japonica, etc. increased. The soil respiration of a Miscanthus type grassland changed according to the existence of burning. The soil respiration rates of burned Miscanthus type grassland were lower than that of unburned grassland. The germination rate became high when the seeds of Vicia japonica were dipped in hot water.
