Green Forestry? Case Studies of Sustainable Forestry and Forest Certification

Foster, Bryan 24 June 2008 (has links)
Abstract This dissertation explored sustainable forest management from multiple perspectives: a literature-based investigation to define management practices that sustain ecological, economic, and social forest resources over time; a field-based research project to identify management practice differences between Forest Stewardship Council (FSC) certified, Sustainable Forestry Initiative (SFI) certified, and uncertified properties in Maine; and a field-based research project to identify stand structural differences between FSC certified and uncertified properties in Vermont. Based on an extensive literature review, we developed an iterative decision-making framework of goal-setting/implementation/ monitoring/review that could assist forest owners in choosing management practices to sustain ecological, economic, and/or social capital over multiple time frames. Our unique contribution is the identification of six concrete management concepts at the implementation phase: (1) BMPs/RIL, (2) biodiversity conservation, (3) community forestry, (4) forest protection, (5) sustained forest product yield, and (6) triad forestry. Forest owners can implement practices under one or more of these concepts to achieve their sustainability goals. We illustrate a hypothetical application of our framework with a case study of an FSC certified managed natural forest in the lowland tropical region of Costa Rica. In the white pine forests of south-central Maine, we compared three FSC, SFI, and uncertified private properties against local scale Montreal criteria using triangulation of evidence from management documents, staff interviews, and field inspections. Certified properties were associated with improved internal management systems and improved practices for biodiversity conservation. However, our data suggest that certification does not necessarily involve fulfillment of all Montreal criteria, such as adherence to sustained timber yield, consideration of multiple social issues, or ecological monitoring at multiple temporal and spatial scales. In northern hardwood stands in central Vermont, we compared three FSC certified and three uncertified that were analogous in terms harvesting date, silvicultural treatment type, forest type, and general location. The uncertified sites were randomly selected to remove bias. We conducted stand structural analysis of both live trees and standing and downed coarse woody debris, and also developed 10-year growth projections using FVS/NE-TWIGS. Our data suggest that FSC certified stands had similar timber economic value, similar live tree structure, and similar tree carbon storage, but significantly greater residual coarse woody debris than comparable uncertified harvested stands.

Context to a conversation : the contribution of science to sustainable forestry

Cushon, Geoffrey Harold 11 1900 (has links)
The currently topical problems of forest management are issues of trans-science. They can be framed in the language of science but they cannot be resolved in the language of science. They involve historically contingent phenomena for which predictive certainty is not possible and they involve issues of moral, aesthetic and economic value. What is the role of science in contributing to the public debate on what are fundamentally social issues such as clear-cut logging or the preservation of old-growth forests? A history and philosophy of science, in general, and ecological science, in particular, is presented that traces the transition, over the last half century, from a positivist science of universal, timeless, predictable order to a science that attempts to interpret local, particular aspects of nature. The former relies on identifying restricted spatio-temporal scales that facilitate prediction while the latter focuses on an understanding of the causal relations within interrelated systems that facilitate explanation of system properties. A kind of contextual or dialectical holism is advocated wherein system components are considered in the context of the whole and the whole is considered as an epiphenomenon resulting from causal interaction of the parts. A history of forest science is presented that identifies sustained yield forestry as a construct of positivist science. Recent insights by ecological science, into the complexity and contingency of forest ecosystems, reveal the limitations of this simplified view. Moreover, the application of a single large-scale strategy such as sustained yield forestry to managing forests in British Columbia contained value assumptions that no longer reflect the full range of values that the public express. The currently topical debates on clear-cutting, logging in municipal watersheds and over-cutting are offered as examples of how questions of fact and questions of value become linked. Although these debates have been carried on in the language of science they are essentially social issues and cannot be resolved by science. The role of science in contributing to the resolution of social issues, such as the development of a sustainable forestry, is not to develop specific solutions but to contribute to the social dialogue in a subservient fashion. Science can characterize the context in which disagreements about matters of value take place. Science can use its experimental protocols to help society construct living experiments that allow us to learn our way into the future. Science can take part in an equitable conversation on sustainable forestry that will facilitate a better understanding of the beliefs and values of the human component of forested ecosystems.

Upgrading forestry training : three areas for development in Indonesia

Ruhandi, Aep January 1998 (has links)
This study reviews the upgrading of forestry training in Indonesia comprising public, private and local people. The principal aim of this study is to investigate if, and how, forestry training can meet the needs of Indonesia forestry sector as methods of sustainable forest management are developed. Sustainability of forest resources and its underpinning by human resource development systems and processes are currently the primary issues and serious challenges for Indonesia forestry sector. The current capacity of forestry training in Indonesia is considered inadequate to meet the challenge. Forestry training managers and trainers in both public and private sectors, timber company managers and workers, and local people were involved in the human resource development processes to meet the new requirements and to see through the remaining traditional forestry training at the same time. Consideration was given to the weakness of the capacity of the current forestry training and the needs for improvement. The literature review took a theme approach covering the fields of human resource development processes, training and development, the six Indonesia five - year development plans, the guidelines for sustainable forest management of Indonesia and the International Tropical Timber Organisation. The main focus for obtaining data with respect to the respondents and informants was the changes brought about by training. The methodology centred on the design and use of a questionnaire with return rate of 55% from eighty managers of forest concessions, 80% from ten heads of public forestry training centres and 60% from eight private forestry training centres. In addition, a formal interview was conducted with HPH managers, APHI representatives, Forestry officials, local government, and trainers. Semi - structured interviews were conducted with villagers and HPH workers. Observations were conducted of villages within KPHP pilots in Riau, Jambi, Central Kalimantan, and East Kalimantan concerned with Forest Village Development. Teaching sessions of trainers graduated from OTTA at the Wolverhampton University were also observed. These data formed the basis of an analysis of the gap between the ideal future forestry human resource capacity and the current provision in relation to sustainable forest management. Analyses of quantitative data were conducted based on descriptive statistics using Excel. The approach to qualitative data was from open to axial and selective coding. In this study the limitation of upgrading forestry training emerged. This limitation is also endorsed by the users of the training programmes. The forestry extension activities are seen as an integral part of human resource development processes and as such must be with the respect to the forestry training programmes. The sustainable forest management can be justifiably incorporated within the upgrading forestry training. The only high standard of forestry training that can assure a success of forestry development is by providing welltrained foresters. Training has to become a strategic preoccupation of senior executives and top trainers as agent of change, which induces positive work attitudes, commitment, discipline and professionalism.
