"The overall objective of this research is to obtain information that will help managers determine what ecological legacies exist in post-beetle forests. The research is designed to 1) provide information about the ecological value of unsalvaged beetle-infested stands; 2) provide understanding of how ecological legacies may vary; and 3) generate information that would contribute to the development of decision support tools for improving ecological integrity in the post-beetle landscape."--Document.

This report highlights past delivery of the land-based programs and progress of mountain pine beetle research during 2003 & 2004 by the Mountain Pine Beetle Initiative, a six-year program established to address the mountain pine beetle epidemic in western Canada and to reduce the risk of future such epidemics. After an introduction on the epidemic and the Initiative, the report summarizes the accomplishments of the Private Forestlands Rehabilitation Program, the Federal Forestlands Rehabilitation Program (First Nations, National Parks, and Other Federal Forestlands components), and the research & development program (including research on ecology, forest economics, socio-economic processes & risk reduction). Finally, the next steps in the land-based and research & development programs are discussed.

The Canadian government announced the Mountain Pine Beetle Initiative (MPBI) in 2002 to address the socio-economic and ecological consequences of an epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins). The objective of this study was to establish baseline information on the ecological characteristics that occur at different stages of succession, resulting from mountain pine beetle disturbance at different time intervals. Key issues addressed by this study were: the post-beetle ecological character of stands; the ecological legacies that should be sought post-beetle; maintenance of ecological integrity in beetle-damaged landscapes; and the impacts of beetles on regeneration. This paper presents a study of stand conditions following two historic mountain pine beetle outbreaks events in the 1940s and 1980s. The study quantified structural and species composition of stands at different stages of succession (25 years and 65 years), and quantified the differences that occur in forest development between stands with and without disturbance by the beetle. It concludes with several recommendations for management of post-disturbance landscapes.

Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

The 1980 eruption of Mount St. Helens caused tragic loss of life and property, but also created a unique opportunity to study a huge disturbance of natural systems and their subsequent responses. This book synthesizes 25 years of ecological research into of volcanic activity, and shows what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment.
