“…It is interesting that the most recently abandoned field, i.e., the swidden fallows that are 1–2 years old, have the highest proportion of their species being used medicinally. This preference for using secondary vegetation as a source of medicinal plants has previously been demonstrated in the Atlantic Forest of Brazil [24] and also among the ribeirinhos of Amazonian Brazil [26], in dry forest of northeastern Brazil [25] and in Vietnam [27]. It appears that different forests are used and valued differentially, not only with regard to usefulness but also in symbolic-religious terms and together they protect traditional botanical knowledge, people’s health and forests.…”

“…A growing body of evidence however points to these secondary recovering ecosystems as important providers of useful plants. Examples of how secondary vegetation make important contributions to the provision of useful plants come from the Amazon and the Atlantic forests in South America [24-26] and from Vietnam [27]. Here we study this phenomenon, which appears to be general, and we test whether it also occurs in a fallow/sacred-forest cultural landscape mosaic in northern Thailand.…”

BackgroundMany ecosystem services provided by forests are important for the livelihoods of indigenous people. Sacred forests are used for traditional practices by the ethnic minorities in northern Thailand and they protect these forests that are important for their culture and daily life. Swidden fallow fields are a dominant feature of the agricultural farming landscapes in the region. In this study we evaluate and compare the importance of swidden fallow fields and sacred forests as providers of medicinal plants among the Karen and Lawa ethnic minorities in northern Thailand.MethodsWe made plant inventories in swidden fallow fields of three different ages (1–2, 3–4, 5–6 years old) and in sacred forests around two villages using a replicated stratified design of vegetation plots. Subsequently we interviewed the villagers, using semi-structured questionnaires, to assess the medicinal use of the species encountered in the vegetation survey.ResultsWe registered a total of 365 species in 244 genera and 82 families. Of these 72(19%) species in 60(24%) genera and 32(39%) families had medicinal uses. Although the sacred forest overall housed more species than the swidden fallow fields, about equal numbers of medicinal plants were derived from the forest and the fallows. This in turn means that a higher proportion (48% and 34%) of the species in the relatively species poor fallows were used for medicinal purposes than the proportion of medicinal plants from the sacred forest which accounted for 17–22%. Of the 32 medicinal plant families Euphorbiaceae and Lauraceae had most used species in the Karen and Lawa villages respectively.ConclusionSacred forest are important for providing medicinal plant species to the Karen and Lawa communities in northern Thailand, but the swidden fallows around the villages are equally important in terms of absolute numbers of medicinal plant species, and more important if counted as proportion of the total number of species in a habitat. This points to the importance of secondary vegetation as provider of medicinal plants around rural villages as seen elsewhere in the tropics.

“…The tropical forests of Southeast Asia have been acknowledged as one of the richest regions of biological diversity in the world [93] and the loss of such forests may have drastic long-term effects, including changes in regional climate patterns [94]. Field-collected data provides useful information on floristic composition, plant diversity, and on the relationship of individual plant species with their environment and are essential to the understanding of forest ecological dynamics.…”

Detergent Plants of Northern Thailand: Potential Sources of Natural Saponins

2019

View full text Add to dashboard Cite

The natural forests of Northern Thailand are the mother source of many utilisable natural products because of their diverse flora and fauna. Northern Thai people have learned to utilise plants, in particular those of plants with cleansing properties, since the beginning of time. Several local species of detergent plants in Thailand are traditionally used by the locals and indigenous people. However, these plants may become extinct because their habitats have been replaced by industrial agriculture, and their uses have been replaced by chemically synthesised detergents. Researchers need to study and communicate the biology, phytochemistry, and the importance of these plants to conserve natural biodiversity of Northern Thailand. Of many utilisable detergent phytochemicals, natural saponins are known as bio-based surfactant and foaming agents. Their physiochemical and biological properties feature structural diversity, which leads to many industrial applications. In this review, we explained the term “detergent” from the physiological mechanism perspective and the detergent effects of saponins. We also compiled a list of Thai local plants with cleansing properties focusing on the saponin-containing plants. Future studies should investigate information relative to plant environment, ethnobotanical data, and the bioactive compound content of these plants. The knowledge acquired from this study will promote the maintenance of the local biodiversity and the conservation of the detergent plant species found in Thailand.

“…The exploitation of medicinal plant populations in wild without observing the mode of sustainable use is one of the threats to biodiversity (Schippmann, 1997, Schippmann et al 2002. The information on natural resources and their spatial distribution is essential to protect rare medicinal species (Peters, 1996;On et al, 2001;Ghimire et al, 2005;Russell-Smith et al, 2006;Gaikwada et al, 2011;Rokaya et al, 2012).…”

Rhaponticun carthamoides (Willd.) Iljin is a rare medicinal plant listed in the Red List of the Russian Federation. Spatial patterns of its reserves were studied for the monitoring and protection of wild populations at the Kuznetsk Alatau. The dependence of population abundance on environmental factors was revealed by geobotanical profiles. We derived the equation of nonlinear regression for rapid method of determining the weight of subsurface parts by counting the number of shoots. To assess rapidly and monitor the natural reserves we developed a mathematical model describing the abundance of R. carthamoides and its habitat altitude.
