Six 1 m2 quadrates were randomly sampled in five different plant communities during three seasons. A total of 75 species, 62 genera, and 38 families was found with an average biomass of 296.50 g/m2. The dominant species were Utricularia aurea, Hydrilla verticillata and Eleocharis dulcis var. dulcis with the Important Value Index (IVI) 84.66, 54.30 and 31.09%, respectively. This area had a high species diversity with H value 3.24 (Shannon-Weaver diversity index). The aquatic plants grew profusely in the rainy season especially the submerged and the free floating groups whereas the emerged and marginal groups grew profusely in summer. In the northern part of the reservoir, water surface was evenly covered by islets and free floating plants whereas the central part was the habitat of emerged plants such as Nelumbo nucifera and Nymphaea lotus. In contrast, the southern part was open water area and deeper. It was the habitat of submerged plants such as Najas sp.1 and Chara sp.1 without islets and free floating plants. A marginal plant, Caldesia sp.1 was found in the northern part. In addition, at least 34 species of aquatic plants were collected by local people for using as food, fodder and other purposes. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Ethnobotany in Bung Khong Long Non-Hunting Area, Northeast Thailand) ผู้เขียน:Siriwan Suksri, นางสาวศิรประภา เปรมเจริญ, ผู้ช่วยศาสตราจารย์, Chitraporn Thawatphan, Suvit Sangthongprow สื่อสิ่งพิมพ์:pdf AbstractBung Khong Long Non-Hunting Area is located in Nong Khai province, northeast Thailand. It has two forest areas: Don Sawan and Don Mor Thong, which are large lowland evergreen forests of this region. At least 4 villages, 364 households, and 2,566 people live around the two forests. This study focused on ethnobotanical knowledge of the villagers comprising list of useful plants and method of use. Data and plant specimens were collected by interviews with practitioners from 121 households (25%) and plant collecting trips during field studies, respectively, (April 2001, July 2001, November 2001, and April 2002). A total of 203 species, 128 genera, and 67 families were considered as ethnobotanical plants by the villagers. These species were divided into 4 categories (some species overlapped among these categories): 108 edibles (53%), 76 medicinals (37%), 14 construction materials (7%), and 40 for other purposes (20%). Leaf was the most frequently used plant part. Most medicinals were prepared by decoction and immersion in the liqueur for drinking. The villagers gathered the useful plants throughout the year. Most of the useful plants were collected for household uses and a few were collected for selling. |
