Economic Value and Utilization of Biodiversity in Local Communities at Nam Nao National Park, Phetchabun Province

Abstract

Nam Nao National Park, Phetchabun Province is home to thousands of wildlife, flora and fauna, and indigenous people for a long period of time. It is also known as one of the most visited national parks during the tourist season from October to February every year. However, not until recently has the knowledge about the Park???s non-timber forest products (NTFPs) been examined and revealed. This paper, therefore, aims at studying the biodiversity and assessing the economic value of the forest products utilized in Nam Nao National Park between 2012 and 2014. Using interviews and questionnaires, the study showed that 8 categories of NTFPs were prominently used by a large number of residents. The mean gross annual value was THB 23,196.49 per household. Moreover, herbs and spices were recorded as the most popularly used either for commercial or medicinal purposes. The results also showed that the transfer of local wisdom and the sharing of knowledge for herbal treatment play an important role in conserving the NTFPs in this area.
