Impact of NTFP extraction on regeneration, population structure, and species composition [Elektronische Daten] [K. Murali, Uma Shankar, R. Shaanker, K. Ganeshaiah, K. Bawa] Extração de Produtos Não Madereiros Nas Florestas de Biligiri Rangan Hills, India. 2. Impacto da Extração de Produtos Nao Madereiros Na Regeneracao, Estrutura de População e Composicao de Espécies Sustainable extraction of non-timber forest products (NTFPs) has recently gained considerable attention as a means to enhance rural incomes and conserve tropical forests. However, there is little information on the amounts of products collected per unit area and the impact of extraction on forest structure and composition. In this paper we estimate the quantities of selected products gathered by the Soligas, the indigenous people in the Biligiri Rangaswamy Temple (BRT) sanctuary in Karnataka, India, and examine the effect of extraction on forest structure and composition. Two sites, distant (DS) and proximal (PS), were identified based on the proximity to a Soliga settlement. The frequency of different size classes indicates that regeneration overall is poor in the area. The two sites show differences in species richness, basal area, and tree mortality. Furthermore, non-timber forest product species show a greater deficit of small size classes than the timber forest species, suggesting that regeneration is affected by collection of seeds and fruits from non-timber forest product species. Regeneration, however, may also be affected by other anthropogenic pressures such as fire, grazing and competition with weeds.
