Quantification and valuation of non wood forest products.

Abstract

Now a day the reduction of biodiversity due to the increase of the deforestation has made people find ways to preserve forest remainders in Brazil and in the rest of the world. In this context, the non wood forest products (NWFP) became an alternative to assist the conservation of forests, once that, in the most of the cases, the extraction of NWFP doesn’t involve degradation of the forest resources. Being thus, has grown the number of researches on the potential of the NWFP for incoming increase and preservation of the environment, always with the premise to be explored in a sustainable form. For this, its necessary studies concerning biology, distribution and reproductive abundance of the NWFP to be explored. The present article has the aim to provide a panoramic vision about the biometric methods used to evaluated the resource supply, the dynamic of production, the resultant components an the real harvest of the most important kinds of NWFP in the tropics. Also are reviewed studies that estimate the economical value of the forest products.
