"This paper describes the establishment of an interdisciplinary, large-scale ecological research project on the Goosenest Adaptive Management Area of the Klamath National Forest in northeastern California. This project is a companion to the Blacks Mountain Ecological Research Project described by Oliver (2000). The genesis for this project was the Northwest Forest Plan (USDA and USDI 1994a). As a part of the Northwest Forest Plan, a network of Adaptive Management Areas was created in Oregon, Washington, and northern California. One of the primary goals of the Goosenest Adaptive Management Area was to investigate means of accelerating the development of late successional forest properties. Led by researchers from the Pacific Southwest Research Station in Redding, California, an interdisciplinary team of scientists designed an experiment to evaluate the use of mechanical treatments and prescribed fire to accelerate late-successional conditions in the Goosenest Adaptive Management Area. The experimental design features four treatments, each replicated five times. The treatment units are 100 acres (40.5 hectares), plus a buffer area of varying size, but generally close to 328 feet (100 meters) in width. The first of the four treatments features a thinning favoring the reestablishment of pine dominance in the forest (Pine-Emphasis Treatment)--"In brief.

The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology. Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape. This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management. The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues. Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.

The eruption of Mount St. Helens on May 18, 1980, had a momentous impact on the fungal, plant, animal, and human life from the mountain to the far reaches of the explosion's ash cloud and mudflows. Although this intense natural event caused loss of substantial life and property, it also created a unique opportunity to examine a huge disturbance of natural systems and their subsequent responses. Based on one of the most studied areas of volcanic activity, this book synthesizes the ecological research that has been conducted for twenty-five years since the eruption. Research from geology as well as plant and animal ecology has been integrated in this unprecedented look at the complex interactions of biological and physical systems in the response of the volcanic landscape. Lessons from the volcano inform our larger understanding of ecosystem disturbances, natural processes, and the impact of land-use practices. Included are results of significant and long-term research on vegetation, mycorrhizae, plant and animal interactions, arthropods, amphibians, mammals, fish, lakes, nutrient cycling, geomorphology, and environmental management. This comprehensive account will be of value to those interested in natural history, ecology, disturbance, conservation biology, limnology, geoscience, and land management. Questions about what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment are discussed in full detail.
