In the south-east United States, 70% of the forest area is privately owned, by an estimated 5 M landholders. If ecosystem or landscape-level management is to work, cooperation across private ownerships is essential. As a first step in garnering cooperation among landowners, a mail survey was carried out to understand their characteristics, attitudes, beliefs and interest in ecosystem management. A specific area of the Coastal Plain of South Carolina, typical of rural forest-dominated areas of this region, was chosen as the study site. Forestry-related uses, specifically timber production, are the main reasons why over half the respondents own their land. Only one-third of the respondents are familiar with the concept of ecosystem management. However, about 70% are interested in learning more about joint management with other landowners. The major concerns about participating in joint management are loss of land and timber values. Most of the landowners who would participate in a landscape corridor system, for example, want to maintain control of their land rights and limit outside intervention in the process.

The forest flora of eastern North America includes many herbaceous plant species traded in domestic and international medicinal markets. Conservation concerns surrounding wild-collection exist and transitioning to cultivation in agroforestry systems has potential economic and ecological benefits. Costs and revenues associated with adopting forest cultivation were modeled for eight North American medicinal forest plants. Sensitivity analysis examined profit potential in relation to (1) discount rates; (2) propagation methods; (3) prices; (4) growing period; (5) production costs; and (6) yields. Results indicate that intensive husbandry of six of eight species would be unprofitable at recent (1990–2005) price levels. Exceptions are American ginseng (Panax quinquefolius L.), and under certain circumstances (e.g., maximum historic prices, low production costs) goldenseal (Hydrastis canadensis L.). Direct marketing to consumers and retailers might improve grower profits, but is undermined by the availability of cheaper, wild-collected product. We suggest that the North American medicinal plant industry could play a key role in facilitating any transition from wild to cultivated product, perhaps through development of a certification and labeling program that brands “forest cultivated” products. This could generate price premiums, to be passed along to growers, but must be accompanied by aggressive consumer education. A “forest cultivated” certification and labeling program has potential to benefit industry and consumers if assurances regarding product identity and quality are a central feature. Plant species that are not viable candidates for commercial cultivation due to limited consumer demand (i.e., species with “shallow,” erratic markets) are best addressed through proactive government and industry initiatives involving targeted harvester education programs.

In an effort to assess agroforestry adoption potential among a diverse Pennsylvania landowner population, a mail survey instrument was sent to 250 members of the Pennsylvania Association of Sustainable Agriculture (PASA) and 250 members of Woodland Owner Associations (WOA). Current management objectives and production strategies, agroforestry awareness, agroforestry interest, and perceptions regarding the benefits and obstacles to agroforestry adoption were gauged. Market segmentation was performed with a two-step cluster analysis to produce four agroforestry adoption potential models: Timber-Related Practices, Livestock-Related Practices, Specialty Crop-Related Practices, and Non-Adopters. The analyses showed that agroforestry practices could indeed satisfy specific land management objectives within diverse populations. The key to outreach success and adoption will be to engage these landowner groups according to their unique interests and values, and to demonstrate the potential agroforestry has to enhance existing objectives.

Following its inclusion in Appendix II of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the harvest, sale and trade of wild ginseng (Panax quinquefolius) for international commerce has been restricted by law in Pennsylvania since the late 1980s. Since then, exports from the state have declined driving the need to better understand the impact of CITES listing and related state and federal laws. Between 2004 and 2010, we conducted a mixed-methods study in Pennsylvania of stakeholder perspectives on state and federal government conservation efforts and experiences relating to enforcement of harvest and trade restrictions. Results from a survey, key informant interviews, and facilitated group discussions indicate widespread support for ginseng conservation efforts but, not with the CITES driven, top-down regulatory approach. It was widely asserted that ginseng stewardship has been, and will continue to be, governed by personal experience, family teachings, and industry norms and not CITES driven restrictions per se. Moreover, study participants were unable to cite instances where prosecution for ginseng-related “crimes” had occurred within their networks and most believed laws are an ineffective deterrent to “bad behavior.” This emic is externally validated by the fact that agency enforcement is constrained by limited personnel and jurisdictional boundaries, not least of which is an inability to enforce on private lands in the state. These findings suggest that a CITES driven regulatory approach has limitations in actually conserving wild ginseng in Pennsylvania, and suggests that this approach should be complemented by stakeholder supported “bottom-up” partnerships involving greater stakeholder participation, such as government-sponsored or supported ginseng planting programs to counter over-exploitation by collectors and/or extirpation resulting from habitat loss.

Conservation incentive programs have substantial impacts on the nation’s forests and wildlife habitat. There are eight major conservation incentive programs. The Forest Stewardship Program (FSP) provides forest landowner assistance by focusing on resource management plans embodying multi-resource stewardship principles. The Forest Land Enhancement Program (FLEP) is the primary vehicle for cost-sharing. The Crop Reserve Program (CRP) provides for conserving covers on eligible farmland. The Forest Legacy Program (FLP) protects environmentally important private forestlands via conservation easements. The Environmental Quality Incentives Program (EQIP) promotes agricultural production and environmental quality as compatible goals. The Landowner Incentive Program (LIP) provides grants to protect and restore habitat on private lands to benefit federally listed, proposed, candidate, or other at-risk species. The Wildlife Habitat Incentives Program (WHIP) provides for development and improvement of upland and wetland wildlife and fish habitat. Finally, the Wetlands Reserve Program (WRP) offers landowners the opportunity to protect, restore, and enhance wetlands.

Evaluating environmentally sustainable and culturally sensitive approaches to natural resource management issues is a necessary step towards improving livelihoods in rural South Africa. This study assessed the applicability of various agroforestry practices to natural resource management issues in the village of GaMothiba located in the northwestern region of South Africa. Agroforestry assessments were carried out using a community based approach through the application of participatory rural appraisal (PRA) methods. These methods were selected in order to assess the acceptability of agroforestry practices according to the perspective of the local people. The assessment process culminated in a variety of community designed agroforestry interventions. The acceptability of agroforestry practices is largely influenced by the degree of community cohesion, land rights, and cooperation between traditional and municipal authority figures. Understanding the opportunities and constraints of agroforestry adoption in rural sub-Saharan Africa furthers the movement towards community based natural resource management and ultimately a more sustainable approach to rural development.

In the United States, agroforestry adoption has lagged behind progress in agroforestry systems research. This study sought to facilitate the communication of landowner land management objectives, values, knowledge and perceptions of the barriers and benefits to agroforestry through applied social marketing research methods and market segmentation analysis. A mail survey instrument was sent to 250 members of the Pennsylvania Association of Sustainable Agriculture (PASA) and 250 members of Woodland Owner Associations (WOA). Current management objectives and production strategies, agroforestry awareness, agroforestry interest, and perceptions regarding the benefits and obstacles to agroforestry adoption were gauged. Market segmentation was performed with a two-step cluster analysis to produce four agroforestry adoption potential models: Timber-Related Practices, Livestock-Related Practices, Specialty Crop-Related Practices, and Non-Adopters. The analyses showed that agroforestry practices could satisfy specific land management objectives within diverse populations. The method effectively identified similarities in agroforestry adoption scenarios. Market segmentation could be utilised as a social marketing tool to guide future policy development, scientific research, and the efficacy and relevance of future agroforestry research and outreach programs. The next step in program development should include the creation of a statewide multidisciplinary team comprised of university, non-profit association and landowner representation, to develop agroforestry applications relevant to each cluster and promote the practices through landowner-led on-farm demonstrations and workshops.

The viability of bioenergy projects and policies depends in part on the economic availability (supplies and prices) of biomass feedstocks. The Northeast USA is poised with significant woody biomass resources, largely available from forest lands and urban wood waste. Further, the Northeast has great potential to augment feedstock supplies with short-rotation woody crops. Based on the results from a national agricultural simulation model, by the year 2030, the Northeast USA could potentially provide between 4.3 and 25.5 million dry Mg year−1 at farmgate prices of
