To quantitatively analyze the effects of burning, we conducted a vegetation survey in the grasslands in Kirigamine, centralJapan. We classified each species into stages of succession based on the life-history traits of the species and defined thescore of the species in each stand based on the classification. We weighted the scores with a v-value, the product of coverageand height in the quadrat, and summed them to calculate the index of dynamic status. With these indices, we wereable to quantitatively compare the stands in the study area and discern minute differences between the stands with differentlengths of restoration periods since the disturbance of burning. These indices correlated with the v-value of trees,suggesting that the disturbance of burning seemed to affect the trees in the stand. We then calculated the growth of thetree species Pinus densiflora to evaluate its contribution to the index of dynamic status
