“…The category 'others' includes flower, seed, inflorescence, stem, twig, petiole, latex, bulb, tuber and whole plant. The ample use of leaves was due to its continuous temporal availability which has also been reported in many other communities (e.g., Giday 2001;Sajem and Gosai 2006;Yineger and Yewhalaw 2007;Langenberger et al 2009;Rana et al 2009). The plentiful use of leaves can ensure sustainable harvesting of medicinal plants (Halim et al 2007) that provides an incentive to protect and maintain wild populations, their habitats and the genetic diversity (Schippmann et al 2002).…”

Because lack of data impedes the assessment of the conservation of medicinal plants, ethno-medicinal studies are important to fill this gap. This study considered the traditional use of plants for health care by the rural communities in two forested and nonforested regions of Bangladesh. A total of 230 respondents were interviewed accompanied by field observation and voucher specimen collection. Altogether, 68 species of medicinal plants belonging to 38 families distributing over 58 genera were recorded, of which 22 species were common in both regions. Trees were the most commonly utilized growth form and leaves were the most commonly used plant part. Forests and homesteads were the major sources of medicinal plants in forested and nonforested regions, respectively. High use versatility (Relative Importance >1) was represented by 14 species; Emblica officinale L. and Allium sativum L. were the most versatile species. Forty-one individual ailments were treated with the medicinal plants recorded. The ailment categories 'respiratory problems' and 'sexual problems' received the highest score from the calculation of informants' consensus factor (F ic ) in forested and non-forested regions, respectively. The findings could contribute in the pharmaceutical sector by directing further investigation of bio-active compounds in medicinal plants. Secondly, results could inform the clues for conservation strategies of forest resources in that region.

“…Marketability was also shown in other ethnobotanical studies to be a crucial factor in successfully integrating trees into agroforestry systems, e.g. [ 61 ]. In our study area, Eucalyptus plantations can therefore be considered a local strategy to raise and diversify income and mitigate agro-pastoral production risks, even though this exotic species implies, for instance, potential allelopathic effects on cultivated crops [ 48 ] and natural vegetation [ 49 , 50 ].…”

BackgroundAgroforestry is a sustainable land use method with a long tradition in the Bolivian Andes. A better understanding of people’s knowledge and valuation of woody species can help to adjust actor-oriented agroforestry systems. In this case study, carried out in a peasant community of the Bolivian Andes, we aimed at calculating the cultural importance of selected agroforestry species, and at analysing the intracultural variation in the cultural importance and knowledge of plants according to peasants’ sex, age, and migration.MethodsData collection was based on semi-structured interviews and freelisting exercises. Two ethnobotanical indices (Composite Salience, Cultural Importance) were used for calculating the cultural importance of plants. Intracultural variation in the cultural importance and knowledge of plants was detected by using linear and generalised linear (mixed) models.Results and discussionThe culturally most important woody species were mainly trees and exotic species (e.g. Schinus molle, Prosopis laevigata, Eucalyptus globulus). We found that knowledge and valuation of plants increased with age but that they were lower for migrants; sex, by contrast, played a minor role. The age effects possibly result from decreasing ecological apparency of valuable native species, and their substitution by exotic marketable trees, loss of traditional plant uses or the use of other materials (e.g. plastic) instead of wood. Decreasing dedication to traditional farming may have led to successive abandonment of traditional tool uses, and the overall transformation of woody plant use is possibly related to diminishing medicinal knowledge.ConclusionsAge and migration affect how people value woody species and what they know about their uses. For this reason, we recommend paying particular attention to the potential of native species, which could open promising perspectives especially for the young migrating peasant generation and draw their interest in agroforestry. These native species should be ecologically sound and selected on their potential to provide subsistence and promising commercial uses. In addition to offering socio-economic and environmental services, agroforestry initiatives using native trees and shrubs can play a crucial role in recovering elements of the lost ancient landscape that still forms part of local people’s collective identity.

The common use of leaves may be due to their availability, as has also been reported to be in use in many communities (e.g., Giday 2001; Sajem & Gosai 2006;Langenberger et al 2009). The use of leaves is compatible with sustainable harvesting (Halim et al, 2007) and provides with an incentive to protect and maintain wild populations, their habitats and the genetic diversity of medicinal plants (Schippmann et al 2002).…”

Traditional systems of medicine have become a topic of global importance recently. Increased commercialization of economically important medicinal plants has resulted in overharvesting and threatening their survival. The present study was carried out to document the indigenous uses of medicinal plants by the local communities in and around Rema-Kalenga Wildlife Sanctuary, Bangladesh. Data collection was predominantly qualitative recording the species use, identifying their relative importance (RI) and assessing the informants' consensus factor (F ic ) on associated knowledge. We interviewed 140 households of the local community and 5 local herbal practitioners. A total of 44 plant species were in use against 33 ailments under 10 broad disease categories. Five species were found to have high use versatility (RI>1), Emblica officinale L. being the most versatile. Respiratory problems scored the highest F ic value (0.56) involving the use of 30% species recorded. Terminalia bellerica Roxb., Sterculia villosa Roxb., Dillenia pentagyna Roxb. and Terminalia arjuna Bedd. were being harvested commercially. Use by the community, particularly for subsistence consumption ensured sustainable harvesting, but commercial extraction of some species appeared unsustainable. Buffer zone-based commercial farming of medicinal plants with a commercial value could serve a dual purpose of assuring sustainable Alternative Income Generation (AIG) for local communities and conserving the natural resources in protected areas.
