Deforestation is frequently a topic of discussion in the environmental arena, but it is not just the number of trees that matters; the quality of the forest is also important. Even where the forest area is stable or increasing, there are often rapid changes in its character. Natural forests are being replaced by plantations or by intensively managed forests. Around the world, forests are becoming younger and less diverse, in both species and structure; this has important impacts for biodiversity and also affects many human values. In this groundbreaking text, forest quality is discussed as a useful new concept in forest conservation and management. Three main assessment criteria are used: authenticity; environmental benefits; and social and economic benefits. The book describes a methodology and protocol for collecting and analysing data, and outlines in detail the approach required with each indicator. The authors advocate a landscape approach to assessment and demonstrate how assessment works through a series of case studies that show how this approach can be used in many ways to help forest conservation management. This hands-on manual is for professionals involved in forestry, conservation and resource management worldwide, and contains case study material from Europe, Asia, Africa and Latin America that demonstrates practical uses of the new 'landscape' approach to forest conservation.

Considerable emphasis has been placed on the interactions between environmental change and forests in recent years. Reports have been produced detailing scenarios of forest development associated with particular changes in climate. Similarly, scenarios have been produced looking at likely trends in air quality. However, many studies have failed to recognize that some of the biggest changes for forests are related to the socioeconomicenvironment rather that the physical environment. This book considers the interactions between forestry and environmental (climatic) change, from social and economic perspectives.

The Forest Inventory and Analysis program (FIA) is the key USDA Forest Service (USFS) program that provides the information needed to assess the status and trends in the environmental quality of the Nation's forests. The goal of the FIA Quality Assurance (QA) program is to provide a framework to assure the production of complete, accurate and unbiased forest information of known quality. Specific Measurement Quality Objectives (MQO) for precision are designed to provide a window of performance that we are striving to achieve for every field measurement. These data quality goals were developed from knowledge of measurement processes in forestry and forest ecology, as well as the program needs of FIA. This report is a national summary and compilation of MQO analyses by regional personnel and the National QA Advisor. The efficacy of the MQO, as well as the measurement uncertainty associated with a given field measurement, can be tested by comparing data from blind check plots where, in addition to the field measurements of the standard FIA crew, a second QA measurement of the plot was taken by a crew without knowledge of the first crew's results. These QA data were collected between 2000 and 2003 and analyzed for measurement precision between FIA crews. The charge of this task team was to use the blind-check data to assess the FIA program's ability to meet data quality goals as stated by the MQO. The results presented indicate that the repeatability was within project goals for a wide range of measurements across a variety of forest and nonforest environments. However, there were some variables that displayed noncompliance with MQO goals. In general, there were two types of noncompliance: the first is where all the regions were below the MQO standard, and the second is where a subset of the regions was below the MQO standards or was substantially different from the other remaining regions. Results for each regional analysis are presented in appendix tables. In the course of the study, the task team discovered that there were difficulties in analyzing seedling species and seedling count variables for MQO compliance, and recommends further study of the issue. Also the task team addresses the issue of trees missed or added and recommends additional study of this issue. Lastly, the team points out that traditional MQO analysis of the disturbance and treatment variables may not be adequate. Some attributes where regional compliance rates are dissimilar suggest that regional characteristics (environmental variables such as forest type, physiographic class, and forest fragmentation) may have an impact on the ability to obtain consistent measurements. Additionally, differences in data collection protocols may cause differences in compliance rates. For example, a particular variable may be measured with a calibrated instrument in one region, while ocularly estimated in another region.

The book presents the current state and good practices of national forest inventories in monitoring wood resources and demonstrates pathways for harmonisation and improved common reporting. Beyond a general overview over availability and use of wood resources in different countries, it provides a unique collection of original contributions from national forest inventory experts with in-depth descriptions of current NFI methods in assessing wood availability and wood use in European countries, and selected countries from America and Asia.The main topics are national definitions and improvements in common reporting of forests available for wood supply, stem quality and assortments, estimation of change including growth and drain, and tree resources outside forest land. The book is a must-have for everyone who is contributing to national forest inventories either methodologically or operatively, for people who want or need to understand national forest inventory provided data and information on the availability of wood resources. By providing profound knowledge it is a valuable basis for scientists involved in scenario modelling and analysing effects of climate change, as well as individuals in private organisations and public administrations promoting the sustainable use of natural resources and the potential of green economy.

Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.

The world's forests are disappearing at an alarming rate, and with disastrous consequences. Demand for wood and paper products ranks high amongst the causes of deforestation and forest degradation, and is now the major cause of loss in those forests richest in wildlife. There is a great deal to be done to improve the timber industry before our forests are safely and sustainably managed. Bad Harvest presents an incisive account of the role that the timber trade has played in the loss and degradation of forests around the world. It examines the environmental consequences of the trade on boreal, temporal and tropical regions, and its impacts for local people working and living in the forests. It also looks at the changing nature of the trade, and assesses current national and international initiatives to address the impacts of deforestation. Finally, the authors show how things could be improved in the future, by presenting a new strategy for sustainable forest management. Based on 15 years of extensive research - particularly work carried out by the World Wide Fund for Nature - Bad Harvest is essential reading on the subject; not only for environmentalists, but also for those in the timber trade seeking to improve the management and reputation of their product.

In the eastern Himalayan Kingdom of Bhutan, culture, society, economy and environment are linked in the development framework of Gross National Happiness (GNH). In this literature review, we highlight the relationships between forests and Bhutan’s development framework and current priorities, identifying plausible causal pathways. Due to the mountainous nature of this country, our particular interest is in the impacts of upstream forest activity on downstream stakeholders. Our hypothetical framework identifies specific causal pathways between forests and the four pillars of GNH (environmental conservation, cultural preservation, equitable socioeconomic development and good governance), and evidence was sought in the published literature to test the hypothesis. While conceptual support for many linkages between forests and each of the pillars was found in the literature, evidential support specifically for Bhutan is limited. The strongest evidence is found for the role of forests in socioeconomic development and good governance, particularly through the community forestry program. To develop incentive programs for forest conservation and restoration, such as payment for ecosystem services and pay-for-performance donor funding, the evidence base needs to be expanded for causal pathways between upstream forest condition and downstream security, particularly for services such as water regulation. The evidence should inform public policy and forest management strategies and practices.
