Very High Food Plant Diversity among Ethnic Groups in Northern Thailand
No full textThe combination of the high biodiversity and many ethnicities in Thailand results in extensive ethnobotanical studies, especially in the northern part of the country. Here we have assembled 7620 records from 60 references regarding how plants are used for food among 14 ethnicities in northern Thailand. The uses are based on 1182 different plant species. Vegetables are the most common food category, which contributed more than 60% of all use-reports and involved nearly 900 species. This was followed by the dessert fruit category, which included about 350 species and over 1800 use-reports. The similarity among the different ethnicities was low and the number of uses and species recorded among different ethnicities were significantly related to the number of studies that had been conducted for each group. This implies that additional ethnobotanical studies are still needed in order to conserve and compile the valuable traditional knowledge related to food plants. Many exotic species are now an important part of traditional knowledge, whereas rare endemic species are uncommon among wild food plants. This situation leads to a loss of traditional knowledge about food plants and reduced awareness of their importance. As a key to using this great reservoir of food for local people, traditional knowledge related to local wild food plants can contribute to the zero-hunger goal of the Sustainable Development Goal (SDG). More studies on the nutrient content and health properties of these plants could lead to the development of new crops to meet present consumer demands
Dynamics of Plant Community and Carbon Storage in Pine Deciduous Dipterocarp Forest in Queen Sirikit Botanic Garden, Chiang Mai Province, Thailand
No full textQueen Sirikit Botanic Garden is situated in Chiang Mai Province, Thailand, abundant with tropical plant communities. This study aims to monitor the structure of plant community and the carbon storage in the biomass of Pine-Deciduous Dipterocarp forest (1,040 m. a.s.l.) in the botanic garden. A 100 x 100 m2 permanent plot was established and monitored in 2012 and 2017. The height of plant which had perimeters greater than 14 cm, were measured. After five years of observations, in 2017, an additional species was found, the tree density increased from 398 to 423, the total stem basal area increased from 22.35 to 23.87 and the Shannon-Wiener index increased from 3.06 to 3.08 The average increment rate, ingrowth rate and mortality rate were 5.75 % (1.15 % per year), 9.80 % and 3.52 %, respectively. Total carbon storage in the forest in 2017 was 77.76 ton C/ha which most of them were kept in plant biomass. Additionally, only 3.46 ton carbon was kept in litter fall. The carbon storage was increased from 68.61 ton C/ha in 2010. The increase rate of carbon storage is lower than expected due to the disturbance of forest fires and human activities
Ethnobotany and Ecosystem Services in a Tidal Forest in Thailand
No full textEcosystem services from ecosystems have been providing different kinds of goods to people living in and around them. Here, the ecosystem services of the tidal forest in Thailand were investigated using the ethnobotanical research method. A total of 101 informants living around a tidal forest in Rayong Province, Thailand was interviewed using the free-listing technique. Totally, 48 species and 992 uses were recorded. Among these, the highest use value species included Cratoxylum cochinchinense, Garcinia cowa, Melientha suavis, and Nelumbo nucifera. Half of the informants received income from selling plant products which varied from 75 to 4000 USD annually without a significant difference between male and female informants. We found a significant correlation between economic value and the number of use-reports. Most economic species are food plants except one which was weaving material. Gender equality is supported by the ecosystem services since the difference in knowledge and generated income were not observed. Significantly, our results support that economic value is one of the most important factors to promote the recognition of traditional uses of local plants or on the other hand, the service from the ecosystem. Therefore, to conserve the existence of traditional knowledge, efforts from various stakeholders, e.g., the communities and the local and central governments, are required
High Diversity of Medicinal Uses of Thai Legumes (Fabaceae) and Their Potential in Public Herbal Medicine
No full textEthnomedicinal studies have demonstrated that Fabaceae include the highest number of medicinal species of all plant families in Thailand. To evaluate which legumes hold the greatest potential for development of public herbal medicines, we used ethnobotanical indices to screen traditional medicinal species from 152 literature sources published from 1986–2019. The homogeneity of each use category was evaluated using the informant consensus factor (ICF). The popularity of the used species was evaluated by percentage of fidelity level (FL) and use value (UV). A total of 261 species from 98 genera of legumes were recorded for their traditional medicinal uses. The uses included 5387 use reports that covered treatments of 420 disorders. The ethnobotanical indices pointed to 15 species with high use values (e.g., Biancaea sappan (L.) Tod., Cassia fistula L., Senna siamea (Lam.) H.S.Irwin & Barneby). Nine of these species are already used in public herbal medicine. The other six species should be studied in greater depth, especially to identify their bioactive compounds so they can be developed for use in public herbal medicine

Taxonomic notes. – Recently, an examination of the lectotype and a paralectotype of Rana okinavana revealed that the species is identical with R. psaltes. Therefore, the name R. psaltes is relegated to a subjective junior synonym of R. okinavana (see Matsui, 2007). This author stated that R. psaltes from Taiwan (Chou, 1994) should be mentioned as R. okinavana too.
