Seed bank and regeneration studies of Canarium strictum roxb. - A threatened species of Western Ghats

Studies on the seed production, modes of their dispersal and regeneration patterns of threatened tree species are crucial for the management of their genetic diversity. Seed bank estimation of a threatened species Canarium strictum was conducted from three different locations of Western Ghats of Karnataka using two factorial completely randomized design. The seeds are mainly dispersed by means of ornithochory and mammalochory. The Indian grey hornbill (Ocyceros birostris) and pied hornbills (Anthracoceros albirostris) are the major seed dispersers. The seed densities among the forest ranges are significant but, it is insignificant among the distances. The mean in-situ regeneration studies revealed an insignificant relationship among the forest ranges and distances. The ex-situ regeneration are also insignificant among the forest ranges and distances. The high mean percentage of ex-situ regeneration suggests as a best suitable method to conserve this threatened species.
