Abstract

This research was conducted with the aim of investigating the diversity of non-wood products providing species in Arasbaran forests. 36 sample plots (100 m × 50 m (0.5 ha)) were investigated in a systematic random grid of 800 × 800 m. In each sample plot, each stem was identified as a species, and the frequency and diameter at the breast height of all species were included. Species with non-wood products and species without non-wood products were measured. To investigate and compare the biodiversity were used the Simpson and Shannon-Wiener species diversity indices, the Margalf richness and Mennick richness indices, and for the uniformity of a species of Pylo and Hill uniformity indices. Biodiversity index values were determined using Past software. Paired t-test was used to investigate the effect of species with non-wood products on species biodiversity. The results showed that species non wood products providing species have a relatively large impact on the biodiversity of plant species in the research area. The species richness index and species diversity decrease in the absence of species with non-wood products and the uniformity index increases. This can be considered as an opportunity to create an alternative strategy for sustainable forest management by participating and allowing the local community to use non-wood resources instead of destructive uses such as wood harvesting or land use change. Incentivizing the use of non-wood products can contribute to the sustainable livelihoods of local communities, which, if realized, can attract their interest for better forest conservation and development.
