A study on the economic value of plants being extracted from a coniferous forest of the Miandam valley of District Swat was conducted during Spring and Summer 2008. The aim of the study was to identify non-timber forest product plants being used from the target area, to identify the trade network that they are sold into, and to evaluate their value as they move within that network in order to make recommendations for socio-economic development of the area. Information was learned through semi-structured questionnaires and participatory interviews with resource uses and traders. 214 species in 79 families were identified as being useful in traditional livelihood. Of these, 150 were herbs, 36 trees, 26 shrubs and 4 climbers. Plant species are locally used as medicinal (115), multipurpose (35), fodder (31), fuel (30), vegetables (12), tools (12), timber (9), poisons (7), roof thatch (7), wild fruits (6), fences/hedges (5), veterinary (5), mud supporter (5), foods (4), spices/condiments (4), religious (4), honey bee (3), brooms (3), and evil repellent (1). Twenty out of 115 medicinal species are collected to sell. The gatherers have very little marketing skills and are often not aware of the high market value. As a result, most of collected materials are sold to local middlemen at low prices.The study revealed that the availability of important medicinal and aromatic plant species is decreasing and the number of rare and threatened species among the medicinal and aromatic plants is increasing. Further study is, therefore, required to quantify the availability of species and to suggest suitable method for their production and conservation. Recommendations are, therefore, given in the spheres of training in identification, sustainable collection, value addition, trade monitoring and cooperative system of marketing.
A study on the assessment of local management practices on the population of three medicinal plants viz.: Persicaria amplexicaule. D. Don., Valeriana jatamansi Jones and Viola serpens Wall ex Roxb was conducted during 2002-2004 in the coniferous forest of Northern Parts of Pakistan. The objective of the study was to know the impact of current management practices on the population size of targeted plants. The study showed that the involvement of locals in the gathering of targeted plants varied with the change in elevation. Among the targeted plants V. serpens was collected by large majorities of people (83.3%) at 2700 m followed by 72% at 2300 m and 37% at 1900 m. V. jatamansi was harvested by a small number of people (18.1%) at 1900 and 2300 m each, followed by 8.3% at 2700 m. While P. amplexicaule was harvested by a few collectors (9.1%) at 1900 m and 9.6% at 2300 m followed by 8.3% at 2700 m. The study concluded that these species have been extracted so heavily in the past that they are found now sparsely in some sites of the study area. Secondly, due to loss of its habitat by deforestation and encroachment of land for cultivation its population is on the decline towards extinction. Therefore, the current study recommends the conservation of the remaining populations of targeted plants through active participation of local communities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
