Abstract
Non seed regeneration is an important regeneration strategy found in different vegetation and may play an important role in ecosystem recovery. The present study compares the effect of disturbance on population status and regeneration strategy of Mallotus philippensisin in sal and mixed forest of the region with reference to ramet vs genet. High disturbance induced ramet proliferation from the genets of almost all the girth classes in Mallotus and the number of ramets per genet steadily increased as the genet aged. A positive relation between genet size and the number of ramet was also observed. This phenomenon explains the pattern of distribution of Mallotus in disturbed environment which enables the species to provide the minimum understorey cover to the recurrently disturbed sal forests. Branching order of ramet increased with increase in disturbance level in Mallotus. Genets facing disturbance of D0 level, showed little ramet production. Number of ramets per genet varies from 24.5±3.5 to 112±21 while the inter ramet distance varies from 32.3±5.3 cm to 56.2±9.7 cm under different forests. At D3 level of disturbance, spacers, branched upto III order or more results into vast expansion of root-stock and production of a number of ramets. The sum of basal area for all the ramets per genet complex increased with genet maturity. Inter-ramet distance was greater in plots facing high burning or low disturbance. The population and growth strategy of Mallotus, evidently, helped the recovery process of the degraded forest ecosystem.
