This paper presents a case study from Jumla District, Nepal, investigating local management systems and ecological sustainability of commercial collection of a medicinal plant, spikenard (Nardostachys grandiflora DC, Valerianaceae), growing in alpine meadows. Interviews were undertaken with local collectors, traders, and district forest office staff, and the dynamics of people-plant interactions are analyzed using the Oakerson model. In all, 110 sample plots 1m square were laid out in three areas with differing collection and grazing pressures for recording of floristic composition and abundance of spikenard root biomass. Comparisons show significantly more root biomass in uncollected than collected areas with local management and the interpretation of differences in abundance is discussed. The combination of qualitative and quantitative investigations can provide a framework for the study of people-plant interactions, and this study can serve as first step in a compilation of cases to create a more detailed picture of local management systems of Nepali nontimber forest products in general and commercially collected medicinal and aromatic plants in particular.
