ECOLOGICAL SILVICULTURAL SYSTEMS Unleash the natural power and adaptability of forests with this cutting-edge guide For generations, silvicultural systems have focused largely on models whose primary objective is the production of timber, leading to drastically simplified forests with reduced ecological richness, diversity, and complexity. Ecological silviculture, by contrast, focuses on producing and maintaining forests with “all their parts”—, that is, with the diversity and flexibility to respond and adapt to global changes. Ecological silviculture seeks to emulate natural development models and sustain healthy forests serving multiple values and goals. Ecological Silvicultural Systems provides a comprehensive introduction to these approaches and their benefits tailored to diverse types of forests, designed for forest management professionals. It provides a series of exemplary models for ecological silviculture and surveys the resulting forest ecosystems. The result is a text that meets the needs of professionals in forestry and natural resource management with an eye towards sustaining healthy forest ecosystems, adapting them to climate change, protecting them from invasive species, and responding to changing market forces. Ecological Silvicultural Systems readers will also find: Detailed treatment of forest ecosystems in North America, Europe, South America, and Australia A broad field of contributors with decades of combined expertise on multiple continents Discussion of pine woodlands; temperate hardwood forests, boreal forests, temperate rainforests, and more Ecological Silvicultural Systems is a useful reference for professional foresters, wildlife habitat managers, restoration ecologists, and undergraduate and graduate students in any of these fields.

A field study was established to explore stand structure and development patterns of mature, mixed-species forests in the Interior Cedar-Hemlock (ICH) zone: moist cold subzone of northwestern British Columbia. The species of interest in the study area were: western hemlock (Tsuga heterophylla (Raf.) Sarg.), western redcedar (Thuja plicata Donn), lodgepole pine (Pinus contorta var. latifolia Engelm.), hybrid spruce (Picea glauca (Moench) Voss x sitchensis (Bong.) Carr.), subalpine fir (Abies lasiocarpa (Hook.) Nutt.), and paper birch (Betula papyrifera Marsh.). Eighty stand structure plots, 150 to 600 m2 in size, were used to assess the species, size and age variation within the study area. Three representative plots, 1,000 m2 in size, were then selected for destructive sampling. Stand reconstruction techniques were used to: 1) characterize the existing species, age and height / diameter structure, 2) describe and quantify the historical height development pattern, 3) describe the development stage and spatial pattern of the stand and it's different components and 4) determine the influence of the above characteristics on the current stand composition and structure. The study stand is 135 years old and originated after a stand destroying wild fire. The resulting mixed-species stand had a very long recruitment period and is currently near the end of the stem exclusion stage of development. Because of the variety of growth patterns exhibited by the different species, neither individual tree height nor diameter were good indicators of stand age structure. The age structure and stage of development were much better defined by direct measures of age, stand density, the diameter distribution / mortality relationship or the overall spatial pattern. Although partially influenced by age structure and spatial arrangement, the developmental pattern of the mixed-species stand was most strongly related to individual height growth characteristics and inter-tree competition. While lodgepole pine, hybrid spruce, western redcedar and paper birch developed in height along characteristically predictable lines, western hemlock exhibited a number of different growth patterns. Subalpine fir followed an atypical, aggressive height growth pattern, developing more like a pioneer species. The variety of height growth patterns frequently allowed younger trees to overtop older individuals, both within and between species. This resulted in numerous shifts in height dominance by different species during the first 80 years of stand development. Forest structure is intimately related to disturbance type and intensity, site quality and the availability of seed or propagules for regeneration. This study examined the structure and development pattern of one type of mixture of tree species common to the ICH zone of northwestern British Columbia. Any difference in the factors listed above would likely produce a different species mixture and therefore a different structure and development pattern. Because most silvicultural operations are tied to the different structures at various stages of stand development, a more complete understanding of these patterns will allow managers to better predict the growth impacts of a variety of treatments and work with, rather than against the natural system.

Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

We reconstructed the stand structure and composition for two western Washington old-growth forest stands harvested around 1930 (named Fresca and Rail) from field and historical data. Both old-growth stands had a codominant or dominant 250-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) overstory with a few scattered older Douglas-fir. Western hemlock (Tsuga heterophylla (Raf.) Sarg.) was codominant at Rail but was predominantly in the mid-story and understory at Fresca. The Fresca site is now dominated by Sitka spruce (Picea sitchensis (Bong.) Carr.) and western hemlock, whereas Rail has a composition similar to the previous old-growth stand. Events taking place early in succession are probably responsible for the differences between the modern and historical stands. Accelerated restoration of old-growth structural diversity may be possible at both sites through repeated creation of artificial gaps, but Fresca will remain different from its historical composition.

Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.

Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

Increasing evidence suggests that the composition and spatial configuration – the pattern – of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.
