Abstract
Year of Publication 2011
Schizostachyum dullooa (Gamble) Majumder ‘dolu bamboo’ is a thin walled sympodial moderate sized
to large tufted bamboo, dominant in the successional fallows of northeast
India. The impact of resource management on productivity and sustainability of
the species was evaluated by investigating the population status and
regeneration in Cachar tropical semi evergreen forest under private property
resource management (PPRM) and common property resource management (CPRM)
regimes. Population status revealed current-year, one-year, two-year and
three-year-old culms contribute 54%, 24%, 16% and 6% of the total culms per
clump, respectively, under PPRM. Three-year-old culms were absent in CPRM and
population status was thus represented by current year (83%), one-year (16%)
and two-year (1%) old culms. Net change, rate of change and % gain in
population for different age classes showed the prevalence of management
practices under CPRM was unscientific. Efficiency of new culm production per
clump used as an index of regeneration was 69.7% in PPRM and 59.88% in CPRM.
New culms produced under CPRM were small and thin. We conclude that CPRM is
inappropriate for a long term economic and ecological sustainability of the
species and alternative management protocols are needed for conservation of the
species.
