The Welfare Effects of Restricting Off-Highway Vehicle Access to Public Lands

Off highway vehicle (OHV) use is a rapidly growing outdoor activity that results in a host of environmental and management problems. Federal agencies have been directed to develop travel management plans to improve recreation experiences, reduce social conflicts and diminish environmental impacts of OHVs. We examine the effect of land access restrictions on the welfare of OHV enthusiasts in Utah using Murdock’s (2006) unobserved heterogeneity random utility model. Our models indicate that changing access to public lands from fully “open” to “limited” results in relatively small welfare losses, but that prohibiting access results in much larger welfare losses.Off-highway Vehicles, Recreational Access, Unobserved Heterogeneity, Random Utility Model, Environmental Economics and Policy, Land Economics/Use,

Smad-mediated regulation of microRNA biosynthesis

AbstractmicroRNAs (miRNAs) are small non-coding RNAs conserved in metazoans. Depletion of miRNAs results in embryonic lethality, suggesting they are essential for embryogenesis. Similarly, pathways induced by growth factors of the transforming growth factor β (TGF-β) superfamily control cell growth, differentiation, and development. Recently Smad proteins, the signal transducers of the TGF-β pathway, were found to regulate miRNA expression, which, in turn, affects expression of numerous proteins. Smads modulate miRNA expression through both transcriptional and post-transcriptional mechanisms illustrating the complexity of gene regulation by TGF-β. In this chapter we summarize the current knowledge of mechanisms underlying Smad-mediated regulation of miRNA biogenesis

Civic Environmental Stewardship: Aligning Organizational and Participant Motivations

Natural area management and sustainability in cities is ever more reliant on civic environmental stewardship. Many conservation organizations sponsor stewardship programs that enlist volunteers to care for the land and restore urban ecosystems. Stewardship program success depends on alignment of individuals’ and sponsoring organizations’ goals. We conducted surveys with a sample of 165 volunteers across natural areas stewardship events in metropolitan King County (Washington, U.S.). An adapted Volunteer Functions Inventory framework was used to understand volunteers’ motivations, satisfactions, and volunteering history. Our findings confirmed the multidimensional dynamics of volunteerism, as stewardship volunteers were motivated and expressed satisfaction for practical altruism, social interactions, experiential learning and a sense of positive impact. High frequency volunteers expressed higher values across all satisfactions outcomes. People who participated in stewardship events closer to home indicated higher event-related social esteem and personal efficacy. Overall, volunteers were generally of greater education attainment, more affluent, and culturally identified as white at a higher rate than the region’s populace, suggesting the need for program innovations to improve stewardship participation diversity. Findings that differ from more general volunteer studies indicate volunteers’ concerns for other people and the environment, in the near term and as legacy for the future. Stewardship organizations’ programs are guided by goals and values. A systematic approach to knowledge building about volunteer motivations can inform more successful volunteer engagement, such as recruitment and retention

Linkages to Public Land Framework: Toward Embedding Humans in Ecosystem Analyses by Using “Inside-Out Social Assessment

This article presents the ‘‘Linkages to Public Land’’ (LPL) Framework, a general but comprehensive data-gathering and analysis approach aimed at informing citizen and agency decision making about the social environment of public land. This social assessment and planning approach identifies and categorizes various types of linkages that people have to public land and guides the tasks of finding and using information on people in those linkages. Linkages are defined as the ‘‘coupling mechanisms’’ that explain how and why humans interact with ecosystems, while linkage analyses are empirical investigations contextualized both temporally and geographically. The conceptual, legal, and theoretical underpinnings of five basic linkage categories (tribal, use, interest, neighboring land, and decision making) and further refinement into subcategories are explained. These categories are based upon the complex property and decision-making regimes governing public land. Applying an ‘‘inside-out’’ analytic perspective, the LPL Framework assesses the social environment inside public land units and traces linkages out into the larger social environment, instead of assessing the outside social environment (communities or stakeholders) and assuming linkages exist between the social entities and public lands, as is generally done in social assessments. The LPL Framework can be utilized in management activities such as assessing baseline conditions and designing monitoring protocols, planning and evaluating management alternatives, analyzing impacts of decisions, structuring public involvement and conflict management efforts, and conducting collaborative learning and stewardship activities. The framework enhances understanding of human dimensions of ecosystem management by providing a conceptual map of human linkages to public land and a stepwise process for focusing and contextualizing social analyses. The framework facilitates analysis of the compatibilities, conflicts, and trade-offs between various linkages, and between cumulative human linkages and capabilities of public land to sustain them. While the LPL Framework was developed for use in planning for U.S. National Forests, it could be applied to other types of public land in the United States and adapted and extended to public lands and common property areas in other countries

Two of the biggest concerns facing rural communities in the Intermountain West today are the contrasting problems of rapid growth and development as opposed to economic decline and stagnation

A Framework for Understanding Social Science Contributions to Ecosystem Management

We propose a framework for understanding the role that the social sciences should play in ecosystem management. Most of the ecosystem management literature assumes that scientific understanding of ecosystems is solely the purview of natural scientists. While the evolving principles of ecosystem management recognize that people play an important role, social considerations are usually limited to political and decision-making processes and to development of environmental education. This view is incomplete. The social science aspect of ecosystem management has two distinct components: one that concerns greater public involvement in the ecosystem management decision-making process, and one that concerns integrating social considerations into the science of understanding ecosystems. Ecosystem management decisions based primarily on biophysical factors can polarize people, making policy processes more divisive than usual. Ecological data must be supplemented with scientific analysis of the key social factors relevant to a particular ecosystem. Objective social science analysis should be included on an equal basis with ecological science inquiry and with data from public involvement. A conceptual framework is presented to communicate to ecological scientists the potential array of social science contributions to ecosystem management. http://www.esajournals.org/doi/abs/10.1890/1051-0761%281998%29008%5B0891%3AAFFUSS%5D2.0.CO%3B2 http://www.esajournals.org/doi/abs/10.1890/1051-0761%281998%29008%5B0891%3AAFFUSS%5D2.0.CO%3B

Slickrock Trail Mountain Bike Survey: Implications for Resource Managers and Area Communities

The Moab Slickrock Trail was the first trail designated primarily for mountain bike use and is one of the most popular mountain bike trails in the world. It was established as a motorcycle trail in 1969, but by the mid 1980s, it was primarily used by mountain bikers. The trail is located on a sandstone plateau overlooking the Colorado River, Moab Valley, and Arches National Park.
