What works in the field? A comparison of different interviewing methods in ethnobotany with special reference to the use of photographs

Economic Botany (Impact Factor: 0.77). 04/2007; 61(4):376-384. DOI: 10.1663/0013-0001(2007)61[376:WWITFA]2.0.CO;2

ABSTRACT Ethnobotanists use a variety of interview techniques to collect ethnobotanical data. Drawing upon the results from a quantitative
ethnobotanical study in five Yuracaré and Trinitario communities in the Bolivian Amazon, the pros and cons of the following
methods are evaluated: (1) interviews in situ during transects, walk-in-the-woods, and homegarden sampling; and (2) interviews ex situ with fresh plant material, voucher specimens, or plant photographs as reference tools. Although the systematic use of plant
photographs for ethnobotanical interviews is poorly documented in literature, the results show that indigenoùs participants
in our study recognize significantly more plant species from photographs than from voucher specimens. It is argued that, especially
in remote and isolated study sites, photographs might be advantageous over voucher specimens.

    ABSTRACT: Arecaceae Schultz-Sch. (Palmae Juss.), a member of the monocotyledon group, is considered one of the oldest extant angiosperm families on Earth. This family is highly valuable because of its species diversity, its occurrence in a wide range of habitats, and its status as an integral part of the culture and the family-based economy of many traditional and nontraditional communities. The main objectives of this study were to perform an ethnobotanical study involving these palms and a "Quilombola" (Maroon) community in the municipality of Cavalcante, GO, Brazil. The variables gender, age, and formal schooling had no influence on the number of species recognized and used by the Kalungas. Ethnobotanical studies based on traditional knowledge in addition to use and management of palms are fundamental aspects for planning and appliance of public policies directed to the use of natural resources and improvement of life quality.

    ABSTRACT: We here tease apart the ethnopharmacological knowledge of plants in two Thai villages to determine to which degree the uses are particular to individual ethnic groups and to which degree they are part of a generalized and uniform set of widespread medicinal plants used over a large geographic range. We compared Karen and Lawa knowledge of medicinal plants in the Mae Cheam watershed of northern Thailand, where both ethnic groups have settled and share ecological conditions for resource extraction. We were interested in documenting the degree to which these two ethnic groups use the same or different medicinal plant species. The use of the same plant species by the two groups was considered a sign of uniform and cross-cultural local knowledge, whereas the use of different medicinal plants by each group was considered a sign of culturally specific local knowledge that developed within each ethnic group.
