A Review on Gregarious Flowering of Bambusa arundinacea in Khurda Forest Division, Orissa

Gregarious flowering in bamboo is a very rare natural phenomenon. The average time span between two such flowerings in Bambusa arundinacea is 50 years. But the data on this account is very staggered and insufficient. Observations on the gregarious flowering was taken for each forest block for a period of three years from 2006-2009. Based on the field observations, an effort has been made to document and map the gregarious flowering of this species in Khurda Forest Division, Orissa. The bamboo forests of Nayagarh district flowered gregariously, while the bamboo clumps in Berberra forests of Khurda district, did not flower during the period. This variation is in conformity with the earlier gregarious flowering reported in this division.
