"Non-timber forest products (NTFP) are extensively extracted from Indian forests, and their role in rural and forest economies is immense. However, the long-term ecological sustainability of NTFP extraction with respect to resource populations, dependent animal species and ecosystem functioning has remained largely unexamined. In this article NTFP research undertaken in India is reviewed in an attempt to understand issues related to ecological aspects of NTFP extraction in India. From the few available studies, it appears that species differ in their responses to harvest depending on the plant part extracted, natural history attributes and harvesting techniques. However, regeneration and population densities of some NTFP species are reported to be adversely affected by extraction. Such adverse effects, though, cannot be attributed to NTFP harvests alone, but rather to a combination of harvests, damaging harvesting practices and accompanying anthropogenic disturbances such as fire, grazing an fuel wood collection. There is little information on the long-term indirect effects of NTFP extraction on dependent animal species. The available literature also indicates a disturbing trend of eco-system simplification due to intensive forest use, including extraction of NTFP, which may gradually lead to the weeding out of vulnerable plant species from Indian forests. Much more research is required before it can be clearly understood to what extent and in what ways livelihoods based on NTFP can be compatible with biodiversity conservation." |
