- Abstract
The conventional management system, consequences of bamboo extraction on culm characteristics and culm population structure of dolu bamboo (Schizostachyum dullooa), a prioritized forest bamboo species were studied in a forest patch of Cachar district, Barak Valley, Assam, North-East India. The resource extraction exhibited unscientific management strategies being practiced that exert greater pressure on the sustainable productivity of the stand. Average culm growth parameters such as culm height, culm DBH, culm internode length, and culm wall thickness were 6.63 m, 2.99 cm, 19.6 cm, 0.42 cm respectively. Harvesting of culms was practiced throughout the year with a greater intensity during May 2004-August 2004 (38% of the total). A loss of 28 percent of total number of culms per clump was observed during the period May 2004 to May 2005. Culm population structure showed a preponderance of younger culm ages over older ones with the culm ages of current, one and two year old culms. We argue the urgent need of an integrated approach for the conservation of the species from the characterization of culm characteristics and culm population structure studied. Management strategies for the restoration of the bamboo stand are proposed.
