"The Great Bear Rainforest Order (GBRO), established January 2016, presents legal objectives for the protection of Old Forests and Red- and Blue-Listed Plant Communities (Listed Communities) within the timber harvesting land base of the Great Bear Rainforest. Although the direction on management and conservation of both Old Forest and Listed Communities is conceptually straightforward, practical field implementation is challenging due to the lack of explicit field assessment criteria. This guidance document provides an overview of key aspects of the GBRO with respect to Old Forest and Listed Communities, and interpretation of the text in the GBRO with reference to current ecological concepts. Additionally, the document discusses how the GBRO text relates to the B.C. Conservation Data Centre methods for assessing Red- and Blue-Listed Ecological Communities. A set of field keys is provided to facilitate consistent application of ecological concepts to meet the intent of the GBRO objectives for Old Forest and Sufficiently Established Listed Communities. The keys incorporate initial minimum criteria for certain ecological features, and an index that integrates a suite of old forest attributes (the Forest Attribute Score) based on features that reflect the complexity of these older coastal, forested ecosystems. Both keys require the field practitioner to determine stand age and occurrence of a Veteran Overstory Tree layer. To evaluate the requirement for protection of Listed Communities, the level of understory development must also be evaluated. Calculation of a Forest Attribute Score requires the assessment of six stand attributes: density of Veteran Overstory Trees, density of large snags, vertical canopy differentiation, understory shrub and herb cover, amount of coarse woody debris, and stand disturbance history."--Publisher's website

Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

This report's objectives are to characterize the growth that has occurred on the PSPs on the Knife Creek Block of the Alex Fraser Research Forest, located near Williams Lake, British Columbia. Since establishment in terms of a number of variables including volume and various biomass components, and to relate the growth that has occurred to underlying stand structure conditions in each of the plots.

Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

This volume provides information about the terrestrial, freshwater, and marine habitats of Oregon and Washington and the wildlife that depend upon them; it also supports broader and more consistent conservation planning, management, and research. The 27 chapters identify 593 wildlife species, define some 300 wildlife terms, profile wildlife communities, review introduced and extirpated species and species at risk, and discuss management approaches. The volume includes color and bandw photographs, maps, diagrams, and illustrations; and the accompanying CD-ROM contains additional wildlife data (60,000 records), maps, and seven matrixes that link wildlife species with their respective habitat types. Johnson is a wildlife biologist, engineer, and habitat scientist; and O'Neill is director of the Northwest Habitat Institute; they worked together on this publication project as its managing directors.
