POST-FIRE REGENERATION OF UMBRELLA BAMBOO (FARGESIA MURIELAE) ON MOUNT SHENNONGJIA IN CENTRAL CHINA

Z. Li and M. Denich

Abstract

Post-fire regeneration of umbrella bamboo (Fargesia murielae), accidentally burned in December 1989, has been studied on Mount Shennongija in Central China.The wildfire strongly influenced the clonal regeneration but did not threaten the vegetative survival of the bamboo. Burned bamboo clumps reached an average density of 99 + 22 culms m-2 and a mean height of 166 + 15 cm in 2000, respectively 34% denser and 35% shorter than the unburned clumps. Modelling on post-fire recovery of culm height suggests that a burned bamboo clumps need at least 13 years to back its full height prior to fire. Fire influence postponed as a critical effect on the seed regeneration after gregarious flowering in 1998-2000. Over 70% of flowered bamboo clumps in the burned site produced no seedlings. The survivor of umbrella bamboo in the burned site is facing a mortal threat.
