We established a study site on the coastal grassland in The Koshimizu Nature Reserve, Hokkaido, Japan. We examined the density and length of vegetative shoots of Rosa rugosa Thunb., which is one of the Japanese wild rose, in an investigation quadrat after an experimental burning. We also checked the flowering shoots in the same quadrat. The density of vegetative shoots increased but the average length of them decreased immediately after the experimental burning. But a few years later, both of them returned to the levels of growth as before burning. Few flowering shoots appeared just after burning, and they increased for three years and subsequently decreased. Therefore, we had better carry out control burning every four or five years for maintenance of the coastal grassland vegetation.
