Comparison of potential non-timber forest products in intensively managed young stands and mature/old-growth forests in south-central British Columbia

Development of understory vegetation has been influenced by the many densely stocked second-growth forest stands in North America, which have an extended stem exclusion successional stage. Understory composition and structure is important for ecosystem functioning, while also having social and economic value through the harvest of certain herb and shrub species. The potential for co-management of young and mature, managed and unmanaged stands for timber and non-timber forest products (NTFPs) was assessed in two separate replicated experiments. Experiment A examined pole-sized lodgepole pine (Pinus contorta) stands that had been pre-commercially thinned (PCT) to target densities of 250, 500, 1000, and 2000 stems/ha. Half of each of these four thinning units was repeatedly fertilized, resulting in eight experimental units. Experiment B examined six different stand types: young plantations, pole-sized lodgepole pine stands either PCT, PCT plus repeated fertilization, or unthinned, mature, and old growth. Fifty-four herb and shrub species were identified as potential NTFPs, with the responses of individual species, as well as mean total herb, shrub, berry-producing and overall total NTFPs being assessed. In Experiment A, mean total abundance (crown volume index) of NTFPs, as well as mean total herb NTFPs were significantly greater in fertilized than in unfertilized stands. Thinning treatments did not significantly affect NTFP volume, however, fertilization treatments produced five significant responses by individual species (Achillea millefolium, Epilobium angustifolium, Taraxacum officinale, Arctostaphylos uva-ursi, Rubus idaeus). In Experiment B, four of the six species responses that were significant had greater abundance in young, managed stands (young plantation, thinned, or thinned-fertilized) than in the unmanaged stands. Mean total NTFP volume and mean total herb NTFP volume also followed this pattern. A. uva-ursi, E. angustifolium, Lonicera involucrata, Sorbus sitchensis and Thalictrum occidentale all had significantly higher abundance in young, managed stands than in all other treatments. Results suggest that co-management for timber and NTFPs is possible in this ecosystem, with further research needed to evaluate livelihood values of these crops.     

Non-timber forest products in rural Mali: a study of villager use

Malian Forest Service activities and policies have evolved since the beginning of colonialism under the assumption that forests and their products are the property of the government. Today the importance of involving local people in forest management is recognized. The purpose of this research was to determine the range of non-timber forest products local people use either for direct consumption or for income generation and to identify the trees/shrubs that yield these products in natural forests, fallow lands and crop fields. A gender analysis of the data was also conducted. The data were collected from face-to-face structured interviews using open-ended questions of 92 randomly sampled households in six Malian villages. One-half of the interviews were conducted with women and the other half were with men. The study identified 55 different non-timber forest products produced by 108 plant species. Almost all (99%) of the products identified are used for personal consumption, whereas 68% of the products are also used to generate income. Products such as firewood, leaves for sauces, shea nuts for oil/butter, seeds for condiments and nuts/seeds for soap are the most frequently mentioned products collected by women. Different categories of products like utensils/house materials, animal feed and construction materials (thatch, poles, mats) are the products most frequently collected by men. Ninety percent of the products collected are found in the natural forests; 63% are collected from trees on fallow lands and 51% from scattered trees in crop fields. Forest Service support of villagers using non-timber forest products would create an economic relationship between the forest and the local people. This is essential for the protection of the forest because people will safeguard their interests.

The Non-Timber Forest Products Sector in Nepal: Emerging Policy Issues in Plant Conservation and Utilization for Sustainable Development

The non-timber forest products (NTFPs) sector in Nepal is being promoted with the concept of sustainable development as articulated by the Convention on Biological Diversity (CBD). Traditionally, people have been dependent on NTFPs for subsistence; however, international trade is growing. To promote this sector, Nepal adopted the 2004 Herbs and NTFP Development Policy. Our goal is to assess the effectiveness of the policy along with the other forestry and natural resource policies in Nepal concerning the conservation and use of NTFPs. We conducted open-ended semi-structured interviews with 28 key informants in summer 2006 in Nepal and collected relevant documents and publications. Qualitative analyses of data yielded important issues that should be addressed to promote the sector as envisioned by the Government. The most important is the need for inventory and research on NTFP species in widespread use. There are some issues regarding species banned under various other National Acts; the lack of marketing information and capacity building; administrative barriers; royalty rates; and illegal harvesting. The most important immediate need is the development of an NTFP Strategy and Action Plan. Our findings should help further implement the policy and promote the sector along the stated mission of conservation and sustainable development.     

Demand for non-timber forest products: Surveys of urban consumers and sellers in Switzerland

In recent years, worldwide socioeconomic, ecological, and cultural changes have led to a paradigm shift in forestry and forest management. Some years ago, most forest enterprises exclusively focused on wood production, whereas today, forest management is expected to be multifunctional and economically as well as socially and ecologically sustainable [Harrison, S., Herbohn, J., Niskanen, A., 2002. Non-industrial, smallholder, small-scale and family forestry: what's in a name? Small-scale Forest Economics. Management and Policy 1 (1), 1–11; Schmithuesen, F., 2004. Forest policy developments in changing societies — political trends and challenges to research. Towards the sustainable use of Europe's forests: Forest ecosystems and landscape research: Joensuu: European Forest Institute, Proc., vol. 49, pp. 87–99]. In this context, non-timber forest products (NTFPs) such as forest honey, mushrooms, or berries could gain importance as an additional source of income for the forestry sector. To assess the market potential of NTFPs in Switzerland, two corresponding surveys were conducted. A consumer survey (N = 897) conducted in six cities in Switzerland investigated the purchase of Swiss NTFPs, consumer preferences, and demand potentials. An additional survey of sellers of NTFPs (N = 105) looked at these aspects from a complementary perspective. The results showed that there is a high esteem and considerable demand potential for such products among urban consumers. Food products were mentioned most frequently. Both consumers and sellers considered quality and environmental friendliness the most important attributes of NTFPs. Structural and organizational innovations and considerable marketing efforts and sales promotion would be required to expand the market for Swiss NTFP, however. Our results indicate that certification of the products' origin, environmental performance, and quality could support such efforts and that recreational and ecological forest services have a synergetic potential for the marketing of NTFPs.

Utilization of non-timber forest products in humid tropics: Implications for management and livelihood

Community dependence on forest resources for diverse needs has high implications for long term management of forests. Sustainable extraction of non-timber forest products (NTFPs) is considered best feasible strategy for forest conservation in biodiversity rich areas. This paper examines the heterogeneity of NTFPs use by tribal communities in northeast India, a global hot spot by examining diversity of NTFPs at-large, its consumption pattern, and contribution to rural income and forest revenue. A total of 343 NTFPs recorded used for diverse purposes by tribal communities. When species choice grouped as per use category, utilization for medicinal (163 species), edible fruits (75 species) and vegetables (65 species) purposes was reasonably high. Community dependence on forest resources was 100% for firewood and house construction material. 76 plant species were sold in three major local markets while an additional 22 species traded at commercial scale mainly outside the state. NTFPs contributed 19-32% of total household income for different tribal communities, which was significant. Illicium griffithii, Rubia cordifolia, Oroxylum indicum, Swertia chirayita, Litsea sebifera, Taxus wallichiana, Valeriana jatamansii, Thalictrum foliolosum, Picrorhiza kurrooa, Everniastrum cirrhatum, Cordyceps sinensis, Aconitum fletcherianum, Nardostachys jatamansi, Picrorhiza kurrooa, Gymnadenia orchidis, Calamus, Quercus and Pinus roxbughii were important commercial species. NTFPs also generated substantial revenue to the State government, though it is falling year after year, which is alarming. To meet community livelihoods, income and forest revenue from NTFPs, it desires a thorough management plan and policy guidelines for these resources from all line departments. The knowledge on diversity, its consumption pattern, and contribution to rural income and forest revenue may enable planners to accurately plan sustainable management of NTFP resources and community development in near future.     

Developing capacity of forest users through participatory forest management: Evidence from Madhupur Sal forest in Bangladesh

Participatory forest management is credited for supporting social learning processes and fostering capacity of forest users for collaboration and collective actions. Despite more than a decade of practice, the empirical evidence substantiating the contribution of participatory management for the capacity development of forest users is scarce. This study assesses a participatory forest management program in Madhupur Sal forest, Bangladesh, by comparing the capacity of de-facto groups of participants and nonparticipants and identifies factors that influence the capacity development. Data were collected using a mixed method approach which combines both qualitative and quantitative methods of data collection. Results indicate that participants differed from nonparticipants significantly in terms of various capacity dimensions related to collective actions. Extension services, credit support, trust within society, information and communication influence the level of capacities in tribal population to adapt and respond to changes. The initiatives to manage natural resources are likely to be more successful if the forest management program initiators consider several factors that influence the capacity development of resource users.     

The compatibility of timber and non-timber forest product extraction and management

We discuss the extent of compatibility of timber and non-timber forest product (NTFP) extraction in two neotropical localities from biophysical, social, and institutional perspectives: the community concession forests of the Petén, Guatemala, and extractivist communities in northern Bolivia. In both localities, timber is harvested via reduced-impact logging (RIL) practices. In Guatemala, the main NTFP extracted is foliage from the understory xate palm (Chamaedorea spp.); in northern Bolivia, the fruits of the Brazil nut tree (Bertholletia excelsa). The Guatemalan case suggests a relatively high degree of compatibility due to low timber harvesting intensities, coupled with temporal, spatial, and social segregation of xate extraction in a well-defined land tenure system. In northern Bolivia, forest management regulations pay little attention to NTFPs and land tenure issues and related conflict complicate efforts to limit timber harvesting impacts on Brazil nut trees. The introduction of timber management plans overlain on customary property rights systems in which the extraction of Brazil nut is organized could undercut its management system. The two case studies suggest that specific legislative, education, and project interventions may help to promote the compatibility of timber and NTFP extraction and management. These include formal training of foresters on NTFP ecology and management while taking into account the perspectives of multiple stakeholders in the design of management plans. Tropical forest users, research managers, and policy makers will also better understand the need for integrated management of timber and NTFPs, if the trade-offs and potential economic benefits from NTFP extraction are clarified.

Non-timber forest products and household incomes in Bonga forest area,southwestern Ethiopia

We identified the major non-timber forest products （NTFPs）, their contributions to household incomes, and the determinants influenc-ing engagement of households in using NTFPs in the Bonga forest area of Gimbo and Decha Districts of Kaffa Zone, southwest Ethiopia. Six Kebeles （the lowest administrative unit in Ethiopia） were sampled from two Districts and 150 households were randomly sampled using propor-tional-to-size techniques based on the number of farm households in each Kebele. Secondary data were collected from and focus group discussions were conducted with selected individuals. The farmers diversified liveli-hood activities such as crop and livestock production, collection of NTFPs and off-farm activities. NTFPs played a significant role in household incomes. The contribution from the major NTFPs （forest coffee, honey and spices） accounted for 47% of annual household in-come. The role of NTFPs was influenced by a number of factors. Vari-ables including being native to the area （＋）, total land holding （＋）, pos-session of livestock （＋） and access to extension （＋） significantly affected forest coffee production. Age of household head （-）, land holding （＋） and distance of the market from the residence （-） significantly affected honey production. Size of landholding （＋）, distance to market （-） and distance of the forest from the residence （-） were significant variables determining the NTFP incomes derived by the households. Attention is needed in the design of policies and strategies for the well-being of households to the contribution of NTFPs to local incomes and the variables that affect the collection of NTFPs must be considered.     

Participatory technology development for incorporating non-timber forest products into forest restoration in Yunnan,Southwest China

Indigenous knowledge has become a topic of considerable interest within the research and development environment. Incorporating indigenous knowledge into state-led ‘top-down’ conservation and development programmes, however, is still a great challenge. This paper presents a case from Yunnan, Southwest China, in which indigenous knowledge has been integrated into the development of an agroforestry model with non-timber forest products for the Sloping Land Conservation Programme (SLCP) by using a participatory technology development (PTD) approach. This approach was adopted to increase the likelihood that technologies developed would be suitable for resource-poor households. It is expected that integrating indigenous and scientific knowledge, will lead to positive ecological and economic outcomes. Finally, the paper argues that the integration of indigenous knowledge in both forestry policy formulation and implementation is important in the context of sustainable forest management in mountain areas.     

Ecological and economical significance of homestead forest to the household of the offshore island in Bangladesh

An explanatory survey was conducted to assess the contribution of plant diversity to the ecological and socio-economic condition of the rural household in the offshore island of Bangladesh.Assessment was done by means of multistage random sampling.The homestead sizes of the study area were classified into 3 groups viz,large (>0.25 ha),medium (0.05-0.25 ha) and small (<0.05 ha) based on the result obtained from a preliminary survey,and a total of 45 homesteads,15 from each group,were selected randomly for the study.The average annual income from homestead's plant diversity varied from Tk 5730.00 (US$95.5) to Tk 17500.00 (US$291.67).The rural people were mainly dependent on their homegarden for woodfuel and nutritional requirement as forest was unavailable in the island.The rural people here also cultivated the plant species as a safety measure from frequent cyclone.Constraints hindering the development of homestead plantation were identified and suggestions were given such as the adequate supply of seedlings of fast growing native species and conservation of endangered species to meet the demand of the household as well as to keep ecological balance.     

Managing Amazonian palms for community use: A case of aguaje palm (Mauritia flexuosa) in Peru

Amazonian palms are prime candidates for sustainable management of non-timber forest products and yet useful species are often harvested destructively. This paper examines a promising management initiative for one of the most useful Amazonian palms – Mauritia flexuosa – in a rural community of northeastern Peru. Based on data from household surveys (n = 57), filmed in-depth interviews, focus groups and participant observation, we identify the factors that influence: (1) the adoption of a locally developed climbing device for wild-harvesting of aguaje palm fruit; (2) the continued practice by some households of palm felling for harvesting fruit; and, (3) investment by households in planting and cultivation of aguaje palm. Our findings identify key conditions for palm management and point to the particular importance of the adoption of palm-climbing devices, not only for reducing wild palm felling but also for stimulating broader community-level conservation as well as efforts to cultivate the palm.     

Diversity of non-timber forest products in Cachar District,Assam, India

We identified 67 and 21 NTFP-yielding plant and animal species, respectively, in a reserve forest in Cachar district of Assam. We recorded globally threatened species listed by IUCN as Critically Endangered （plant species Dipterocarpus turbinatus）, Vulnerable （plant species Aquillaria malaccensis）, Endangered （animal species Hoolock hoolock, Indotestudo elongata and Manis pentadactyla）, and Vulnerable （animal species Nilssonia hurum and Rusa unicolor）. The whole plant or animal and/or their various parts were used as food or medicine, in house construction, magico-religious activities and others. While some NTFPs were harvested throughout the year, others were harvested seasonally. A comprehensive NTFP policy, along with scientific measures for regen- eration, restoration and augmentation of NTFP-yielding plants and animals, would help in addressing the conflicting demands of conservation and livelihood in the forests of this area.     

Agroforestry in the humid lowlands of West Africa: some reflections on future directions for research

Means have to be found for rural people to supply both their own needs and those of the urban dwellers, without further loss of natural resources. Some examples from around the humid tropics suggest that complex agroforests may be able to achieve this goal. In West Africa, the concepts of the cocoa (Theobroma cacao) farm and compound garden, coupled with the domestication of indigenous trees for the production of improved non-timber forest products, need to be developed. There are numerous candidate species both for domestication and for inclusion in multi-strata systems. Research is needed on the development of various forms of multi-strata agroforests, coupled with short-term tree fallows especially to rehabilitate degraded land. More ecologically-oriented studies are required to build sustainable and productive multi-strata agro-ecosystems, while domestication requires greater understanding of the needs of the food and pharmaceutical industries and the development of marketing infrastructures. Incentives are required to promote entreprenurism in rural communities, especially near urban centres. This revised version was published online in June 2006 with corrections to the Cover Date.     

Has deregulation of non-timber forest product controls and marketing in Orissa state (India) affected local patterns of use and marketing

State control of marketing agricultural or forestry products may lead to a trade monopoly and restricted competition, resulting in inequitable returns to producers. Consequently, market deregulation for agriculture and other natural products has been advocated to improve market efficiencies, participation and returns for the producers and local traders. The study examines the impact of deregulation of state marketing controls on collection, sale and returns to extractors and traders from non-timber forest products. It assessed whether deregulation policy resulted in greater benefits to primary extractors and a win–win situation for both producers and traders? Mixed effects were found, with no significant changes in terms of trade, demand, or quantum of consumption; but there was an overall increase in the procurement price for several products following deregulation. The collection and farm gate price of tree based oilseeds and honey increased due to lower transaction costs, and ease of trading with a continued demand for these products. The impact on less valuable products was insignificant. Abolition of monopolistic trading increased competition and had a pull effect on the local market prices of several NTFPs. Although traders paid a higher price to procure products, overall they also benefited being able to sell the purchased products to merchants and manufacturers at a better margin than previously.

Ecological, socio-cultural, economic and political factors influencing the contribution of non-timber forest products to local livelihoods: Case studies from honduras and the Philippines

Discussion of the role of non-timber forest products (NTFPs) in efforts to reconcile the objectives of forest conservation and rural development has often been hampered by limited understanding of the complexity of the factors that affect the contribution of NTFPs to local livelihoods. By drawing upon two case studies where NTFPs play an important role - the municipality of Lepaterique in Honduras and Palawan Island in the Philippines - this study emphasizes that an ideal extractive system should be based on a mix of products to enable sustainable harvesting throughout the year. The study also demonstrates that considerable attention needs to be paid to the socio-cultural heterogeneity of resource users, and to the value chain structure, access and control over resources and political transparency that affect the opportunities for local people to benefit from NTFP extraction.     

The domestication and commercialization of indigenous trees in agroforestry for the alleviation of poverty

New initiatives in agroforestry are seeking to integrate into tropical farming systems indigenous trees whose products have traditionally been gathered from natural forests. This is being done in order to provide marketable products from farms that will generate cash for resource-poor rural and peri-urban households. This poverty-alleviating agroforestry strategy is at the same time linked to one in which perennial, biologically diverse and complex mature-stage agroecosystems are developed as sustainable alternatives to slash-and-burn agriculture. One important component of this approach is the domestication of the local tree species that have commercial potential in local, regional or even international markets. Because of the number of potential candidate species for domestication, one crucial first step is the identification of priority species and the formulation of a domestication strategy that is appropriate to the use, marketability and genetic potential of each species. For most of these hitherto wild species little or no formal research has been carried out to assess their food value, potential for genetic improvement or reproductive biology. To date their marketability can only be assessed by their position in the local rural and urban marketplaces, since few have attracted international commercial interest. To meet the objective of poverty alleviation, however, it is crucial that market expansion and creation are possible, hence for example it is important to determine which marketable traits are amenable to genetic improvement. While some traits that are relatively easy to identify do benefit the farmer, there are undoubtedly others that are important to the food, pharmaceutical or other industries that require more sophisticated evaluation. This paper presents the current thinking and strategies of ICRAF in this new area of work and draws on examples from our program. This revised version was published online in June 2006 with corrections to the Cover Date.
