Their livelihoods largely rely on forest products and other plant resources. Mountain societies have rich traditional knowledge of the use and management of bamboo resources; this is put to practice by rural farmers in their day-to-day life to secure survival and development. Methods Data collection and review of literature A considerable amount of information presented here is based on field investigations undertaken by the authors of this paper. Results were partly published by several authors (Xue et al 1995; Geng and Wang 1996; Wang 1999; Wang 2000; Wang et al 1993; Wang et al 2000; Yang et al 2000; Ma and Zhang 2002) to enrich and support the objectives of conservation and sustain- able utilization of species, as well as preservation of tra- ditional uses in Yunnan province. Interviews with local inhabitants Interviews with local inhabitants provided an important source of information on distribution, habitat, ecologi- cal conditions, and regeneration of bamboo, as well as on indigenous knowledge systems concerning classifica- tion, utilization, management, and conservation of bamboo. Interviews with local inhabitants were con- ducted in 3 phases: Phase 1: Collection of information on bamboo from local villages, to obtain general information on species that are being used and on the vari- ous uses. Personal interviews and question- naires were employed. Phase 2: In order to identify the key species of bamboo used in local communities and to assess their potential for cultivation and development, the second phase consisted in selecting information at individual level in the case study area. Phase 3: Semi-structured interviews and group inter- views were conducted to cross-check data and FIGURE 3 Dai women cooking rice in Cephalostachyum pergracile containers. information obtained during phases 1 and 2.
