Book Description
Forest condition is now assessed annually in most European countries. This field book provides details of assessment procedures used by the Forestry Commission in their main monitoring programme. Although this programme is restricted to Sitka spruce, Norway spruce, Scots pine, oak and beech, the techniques that are described are applicable with little or no modification to most other tree species. While emphasis has been placed on the assessment of crown density, a variety of other indexes are also used. These are described and an assessment system is provided for each parameter. The additional indices enable a full description to be made of the condition of a tree.

Book Description
The Forest Inventory and Analysis (FIA) Program of the Forest Service, U.S. Department of Agriculture, conducts a national inventory of forests across the United States. A systematic subset of permanent inventory plots in 38 States is currently sampled every year for numerous forest health indicators. One of these indicators, crown-condition classification, is designed to estimate tree crown dimensions and assess the impact of crown stressors. The indicator features eight tree-level field measurements in addition to variables traditionally measured in conjunction with FIA inventories: vigor class, uncompacted live crown ratio, crown light exposure, crown position, crown density, crown dieback, foliage transparency, and crown diameter. Indicators of crown health derived from the crown data are intended for analyses at the State, regional, and national levels, and contribute to the core tabular output in standard FIA reports. Crown-condition measurements were originally implemented as part of the Forest Health Monitoring (FHM) Program in 1990. Except for crown diameter, these measurements were continued when the FIA Program assumed responsibility for FHM plot-based detection monitoring in 2000. This report describes in detail the data collection and analytical techniques recommended for crown-condition classification.

Book Description
"The practice and process of assessing trees for risk is detailed in ISA's Tree Risk Assessment Manual. This new manual is a valuable tool for both the expert and novice risk assessor, and will quickly become one of the most referenced resources on your bookshelf. As the companion publication for the Tree Risk Assessment Qualification course, the manual highlights the critical steps in the risk assessment process - from site analysis to risk evaluation and communicating risk to clients (and everything in between). This publication can be used as a resource to study for the qualification course, as a step-by-step guide to conducting a tree risk assessment, and as a desktop reference for writing reports. A Basic Tree Risk Assessment Form is included, along with a list of common wood decay fungi, and a useful glossary of risk assessment terms."--Publisher description

Book Description
The demand for comparable, long-term, high quality data on forest ecosystems' status and changes is increasing at the international and global level. Yet, sources for such data are limited and in many case it is not possible to compare data from different monitoring initiatives across space and time because of methodological differences. Apart from technical manuals, there is no comprehensive multidisciplinary, scientific, peer-reviewed reference for forest monitoring methods that can serve and support the user community. This book provides in a single reference the state-of-the-art of monitoring methods as applied at the international level.The book present scientific concepts and methods that form the basis of the transnational, long-term forest monitoring in Europe and looks at other initiatives at the global level. Standardized methods that have been developed over two decades in international forest monitoring projects are presented. Emphasis is put on trans-nationally harmonized methods, related data quality issues, current achievements and on remaining open questions. - A comprehensive overview of needs, requirements, organization and possible outcomes of an integrated monitoring program - Tested and quality assured, internationally harmonized methodologies based on a complete revision of existing methods carried out in 2009-2011 - Connection with monitoring results allows assessment of the potential of the monitoring method

Book Description
More than half the world's population now lives in cities. Creating sustainable, healthy and aesthetic urban environments is therefore a major policy goal and research agenda. This comprehensive handbook provides a global overview of the state of the art and science of urban forestry. It describes the multiple roles and benefits of urban green areas in general and the specific role of trees, including for issues such as air quality, human well-being and stormwater management. It reviews the various stresses experienced by trees in cities and tolerance mechanisms, as well as cultural techniques for either pre-conditioning or alleviating stress after planting. It sets out sound planning, design, species selection, establishment and management of urban trees. It shows that close interactions with the local urban communities who benefit from trees are key to success. By drawing upon international state-of-art knowledge on arboriculture and urban forestry, the book provides a definitive overview of the field and is an essential reference text for students, researchers and practitioners.

Book Description
The assessment and evaluation of tree condition and vitality is an essential part of the ICP Forests monitoring programme. Due to the complex structure of forest ecosystems, a number of different indicators of tree condition are adopted. In this chapter, they are described also in terms of their ecological relevance. Special emphasis is laid on biotic agents affecting forest ecosystems and explaining tree responses to stressors. For operational reasons, definitions and recommendations for the use of the indicators are given. Tree condition assessment in forest monitoring is closely linked to field measures of Quality Assurance and Control. Examples of results show that the methods currently used in tree condition monitoring are sensitive to detect the effects of climate change on forests and identifying main spatial and temporal patterns and damaging agents.
