Book excerpt: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement (before 1850) landscapes of the Oregon Coast Range. HRV has been defined as the bounded variability of a system within constraints imposed by larger-scale phenomena (e.g. climate, topography) and without significant modern human influence. HRV of landscapes has been proposed as a guide for biodiversity conservation in the past decade. In Chapter 2, I estimated HRV of a regional landscape and evaluated the similarity of current and alternative future landscapes under two land management scenarios to the conditions within the HRV. The simulation results indicated that historical landscapes of the region were dynamic, composed of patches of various sizes and age classes ranging from 0 to> 800 years as well as numerous small unburned island patches. The current landscape was outside the HRV. The landscape did not return to the HRV in 100 years under either scenario largely because of lack of old-growth forests and overabundance of young forests. This study showed that the HRV can provide a reference condition for concrete, quantitative evaluations of landscape conditions and alternative management scenarios if sufficient data exist for estimating HRV. Departure from HRV can serve as an indicator of landscape conditions, but results depend on scale and quantification of landscape heterogeneity. In Chapter 3, I investigated the HRV in live and dead biomass and examined variability in disturbance history and forest stand development. I calculated biomass as a function of disturbance history. The HRV of live and dead wood biomass distributions revealed that the majority of the landscape historically contained> 500 Mg/ha of live wood and 50-200 Mg/ha of dead wood. The current dead wood condition is outside HRV. There was a wide variation in dead wood biomass because of variations in disturbance history. This study suggests that natural disturbance regimes and stand development are characterized by much larger variation than is typically portrayed or appreciated. The HRV approaches to evaluating landscape conditions need to include both landscape and stand characteristics to better represent ecological differences between managed and unmanaged landscapes. In Chapter 4, I used remotely sensed data and historical vegetation data in a GIS to examine changes occurred in vegetation cover since settlement in two major valleys, the Coquille and Tillamook, in the region. I used existing historical vegetation maps of the two valleys and collected historical vegetation data from the General Land Office (GLO) survey records. I characterized current vegetation conditions using an unsupervised classification of satellite images. Historically, the Coquille Valley was dominated by hardwood trees and the Tillamook was by conifers. Valley bottoms in both areas differed in vegetation from nearby uplands. Tree-covered areas have declined substantially in both valleys as a result of agriculture and development. The historical data offered reference conditions for assessment of changes in biodiversity that have occurred in these unique habitats. This thesis illustrates the benefit of using historical landscape information for better understanding of human influence on the landscape. Historical data often have many assumptions and limitations, but ecological impacts of landscape changes on native biota can be better understood by comparisons with historical conditions.

How well do we understand natural forest disturbances and how might we emulate them in forest management? What role does emulation play in forest management? Representing a range of geographic perspectives from across Canada and the United States, this book looks at the escalating public debate on the viability of natural disturbance emulation for sustaining forest landscapes from the perspective of policymakers, forestry professionals, academics, and conservationists. This book provides a scientific foundation for justifying the use of and a solid framework for examining the ambiguities inherent in emulating natural forest landscape disturbance. It acknowledges the divergent expectations that practitioners face and offers a balanced view of the promises and challenges associated with applying this emerging forest management paradigm. The first section examines foundational concepts, addressing questions of what emulation involves and what ecological reasoning substantiates it. These include a broad overview, a detailed review of emerging forest management paradigms and their global context, and an examination of the ecological premise for emulating natural disturbance. This section also explores the current understanding of natural disturbance regimes, including the two most prevalent in North America: fire and insects. The second section uses case studies from a wide geographical range to address the characterization of natural disturbances and the development of applied templates for their emulation through forest management. The emphasis on fire regimes in this section reflects the greater focus that has traditionally been placed on understanding and managing fire, compared with other forms of disturbance, and utilizes several viewpoints to address the lessons learned from historical disturbance patterns. Reflecting on current thinking in the field, immediate challenges, and potential directions, the final section moves deeper into the issues of practical applications by exploring the expectations for and feasibility of emulating natural disturbance through forest management.

Roussopoulos, Director, Southern Research Station The world and its ecosystems are repeatedly punctuated by natural disturbances, and human societies must learn to manage this reality Often severe and unp- dictable, dynamic natural forces disrupt human welfare and alter the structure and composition of natural systems Over the past century, land management ag- cies within the United States have relied on science to improve the sustainable management of natural resources Forest economics research can help advance this scientifc basis by integrating knowledge of forest disturbance processes with their economic causes and consequences As the twenty-frst century unfolds, people increasingly seek the goods and services provided by forest ecosystems, not only for wood supply, clean water, and leisure pursuits, but also to establish residential communities that are removed from the hustle and bustle of urban life As vividly demonstrated during the past few years, Santa Ana winds can blow wildfres down from the mountains of California, incinerating homes as readily as vegetation in the canyons below Hurricanes can fatten large swaths of forest land, while associated foods create havoc for urban and rural residents alike Less dramatic, but more insidious, trees and forest stands are succumbing to exotic insects and diseases, causing economic losses to private property values (including timber) as well as scenic and recreation values As human demands on public and private forests expand, science-based solutions need to be identifed so that social needs can be balanced with the vagaries of forest disturbance processes

Available in PDF, EPUB and Kindle. Book excerpt: Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.

Book excerpt: Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development. Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained. Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity. Examples are presented on how biodiversity assessments can be made. Proposes how the critical gaps in our knowledge identified throughout the book could be filled through macroecological research and international co-operation.

Book excerpt: In 2002 much of the Front Range of the Rocky Mountains in Colorado was rich in dry vegetation as a result of fire exclusion and the droughty conditions that prevailed in recent years. These dry and heavy fuel loadings were continuous along the South Platte River corridor located between Denver and Colorado Springs on the Front Range. These topographic and fuel conditions combined with a dry and windy weather system centered over eastern Washington to produce ideal burning conditions. The start of the Hayman Fire was timed and located perfectly to take advantage of these conditions resulting in a wildfire run in 1 day of over 60,000 acres and finally impacting over 138,000 acres. The Hayman Fire Case Study, involving more than 60 scientists and professionals from throughout the United States, examined how the fire behaved, the effects of fuel treatments on burn severity, the emissions produced, the ecological (for example, soil, vegetation, animals) effects, the home destruction, postfire rehabilitation activities, and the social and economic issues surrounding the Hayman Fire. The Hayman Fire Case Study revealed much about wildfires and their interactions with both the social and natural environments. As the largest fire in Colorado history it had a profound impact both locally and nationally. The findings of this study will inform both private and public decisions on the management of natural resources and how individuals, communities, and organizations can prepare for wildfire events.

Bost and published by . This book was released on 2018 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies magnifica var. shastensis) mortality in a central part of this region - the Russian Wilderness - appears to mirror the timing of these larger forest mortality events and has highlighted the need to investigate if recent levels of mortality are historically unusual. The main objectives of my study were to (1) characterize contemporary tree mortality and determine potential drivers of that mortality using field-measured data, (2) integrate both field-measured data and annual LandTrendr data to assess temporal and spatial patterns of the extent and magnitude of forest decline, (3) assess the relationship between topographic and structural attributes with forest decline, and (4) determine whether climate is a potential driver of forest decline. To characterize contemporary tree mortality and determine potential drivers of that mortality, I established 142 field plots in the summer of 2015 measuring tree health and presence of any pests and pathogens on canopy tree species. Next, I used annualized LandTrendr algorithms across a 28-year time period (1986-2014) coupled with a regional forest type map to determine the timing, extent, and magnitude of canopy decline within each forest type. To assess potential drivers of canopy decline and identify specific vulnerabilities to drought, I used PRISM climate data and random forest classification using topographic and stand structure attributes. Plot data showed the highest proportions of mortality occurred in subalpine fir (Abies lasiocarpa, 35.3%) and Shasta red fir (28.6%), with evidence of fir engraver beetle (Scolytus ventralis) and Wien's dwarf mistletoe (Arceuthobium abietinum subsp. wiensii) on many Shasta red fir individuals (34.7% and 20.4%, respectively). Forest decline was five times higher in the last two years of the time series (2013-2014) than in the previous twenty-six years. The greatest magnitude of decline was found in the red fir and subalpine conifer forest types, findings supported by my field-measured data. Canopy decline was greater at higher elevations, in denser canopies and in stands with larger trees. I did not detect any relationships between annual climate variables and forest decline, possibly due to a discrepancy between the course spatial scale of the climate data and fine-grained scale of forest disturbance, or because only two years exhibited pronounced canopy decline. My study demonstrates effectiveness in characterizing forest decline in a highly diverse landscape using a remote sensing approach and highlights the complexity of climate, pests and pathogens, stand structure, and topography as they relate to tree mortality and forest decline.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical cyclones in Southern Africa, also known as hurricanes or typhoons in other regions of the world, is a hot subject for academic research. This focus has been magnified by the need to consider tropical cyclones in the context of other global development agendas, that includes the 2030 Agenda for Sustainable Development and its inseparable 17 Sustainable Development Goals (SDGs), the Paris Agreement, the Sendai Framework for Disaster Risk Reduction and Habitat III’s New Urban Agenda. The ambitious SDGs challenge global and community leaders to make sure development addresses the nexus among poverty, inequality and employment creation, as well as care for the earth and its natural resources and biodiversity. The SDGs further present an agenda to eradicate hunger, bring quality education and sustain water and sanitation. The infrastructure development, human settlements, sustainable consumption and production, climate change, biodiversity and the ocean (blue) economy agendas are also pitched. Lastly, the 2030 Agenda for Sustainable Development encourages partnerships on delivering various programmes and projects at all spatial levels. However, as tropical cyclones continue to make multiple landfalls and ravage Southern Africa and other parts of the world, the achievement of the 2030 Agenda for Sustainable Development is threatened. To this end, this book addresses this gap by documenting the implications of tropical cyclones, drawing examples and case studies from recent tropical cyclones such as cyclone Idai and cyclone Kenneth that resulted in catastrophic impacts in 2019. The book comes as part of a series with three volumes. The other volumes include “Cyclones in Southern Africa Vol. 1: Interfacing the Catastrophic Impact of Cyclone Idai with SDGs in Zimbabwe” and “Cyclones in Southern Africa Vol 2: Foundational and Fundamental Topics”. Given the foregoing, the book is suitable as a read for several professionals and disciplines such as tourism and hospitality studies, economics, sustainable development, development studies, environmental sciences, arts, geography, life sciences, politics, planning and public health.

This book was released on 2012-09-04 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.
