Special IssuesEcological Consequences of Alternative Fuel Reduction Treatments in Seasonally Dry Forests: The National Fire and Fire Surrogate StudyJames D. McIver and Christopher J. Fettig, editors Vol. 56, No. 1 (February 2010) View Online This special issue of Forest Science features the national Fire and Fire Surrogate study (FFS), a multisite, multivariate research project that evaluates the ecological consequences of prescribed fire and its mechanical surrogates in seasonally dry forests of the United States. The primary goal of the FFS study was to measure the economics, effectiveness, and ecological consequences of commonly used fuel reduction treatments. Study participants applied treatments intended to reduce potential fire risk at each of 12 sites (seven sites in the western United States and five sites in the eastern United States). The treatments were conducted in cooperation with local experts, including fire management personnel, fuel specialists, and silviculturists, and included an untreated control, prescribed fire only (surface fire), mechanical treatment only (usually thinning from below), and a mechanical plus prescribed fire treatment. At each of the 12 FFS study sites, treatments (exclusive of the untreated control) were designed and implemented to achieve stand conditions such that if impacted by a head fire under 80th percentile weather conditions, at least 80% of the basal area represented by dominant and codominant trees would survive (80/80 rule). Treatments were assigned randomly to at least three replicate units, each measuring at least 10 ha. The effects of these treatments were measured on a wide variety of response variables, including the structure and composition of trees and understory vegetation, fuel beds and coarse woody debris, soils, bark beetle activity, and small mammal and avian species abundance. The 11 contributions in this special issue include a lead-off article that describes the history, development, and organization of the FFS study; three articles that document treatment responses on stand structure, fuels, or fire behavior; two articles on the abundance and impacts of bark beetles; and five articles on vertebrate and invertebrate responses to the FFS treatments. The FFS is one of the largest and most comprehensive forestry research projects ever undertaken, and is providing answers to many of the important questions that surround the issue of hazardous fuel reduction and ecological restoration in seasonally dry forests of the United States. Science and Management of Forest Headwater Streams Robert J. Danehy and George G. Ice, editors Vol. 53, No. 2 (April 2007) View Online Purchase Best management practices for forestry and forest practice rules have historically focused on protecting high-order fish bearing streams, but foresters and watershed managers are now recognizing that headwater streams comprise the majority of stream networks and are often strongly influenced by adjacent land. As a result, aquatic stewardship approaches and requirements for headwater streams in managed forests have recently received considerable attention. This attention, particularly in the Pacific Northwest, is focused on anadromous salmonids and the perception that lack of protection to headwater streams leads to deleterious impacts on the physical habitat and water quality of downstream reaches. There is also an emerging recognition that headwater reaches can support important non-fish communities including amphibians. To address these concerns, the Headwaters Research Cooperative (HRC) was founded in 2001 to augment the body of science on headwater streams. The Cooperative, formed by private and public organizations, hosted a meeting in the fall of 2001 to identify ongoing research and research needs related to forest headwater streams. The meeting attracted approximately 100 researchers and policy makers from throughout the Pacific Northwest, British Columbia, and across the United States, who interacted in focus groups on specific topics to develop lists of research priorities. The larger group then developed overall research priorities through consensus. This list became the roadmap for HRC to fund research efforts. HRC-funded research and other research that addressed the priorities list became the material for this special issue of Forest Science. A valuable reference for foresters and watershed managers. US-Canada Forest Products Trade Runsheng Yin, editor Vol. 52, No. 4 (August 2006) View Online Purchase The US lumber industry has long claimed that Canada's administratively determined stumpage prices are a subsidy to Canadian producers, prompting the United States to impose restrictions and tariffs on Canadian imports. Canadian strategic responses have included increasing exports to offset losses and pursuing legal remedies. Against this background, a symposium was held jointly by bilateral academic and governmental institutions in the eastern United States and Canada on March 7-8, 2005. It addressed North American market relationships and industry trends; impacts of past, current, and future US trade restrictions; and views of and approaches to US and Canadian stumpage pricing. The goal was to lend scholarship to the discussion and enhance the understanding of any related policy actions. This special issue of Forest Science includes 14 thought-provoking articles from this symposium. A must-read for industry executives, policymakers, business analysts, and academic researchers. Forest Growth and Yield Chris J. Cieszewski and Mike Strub, editors Vol. 52, No. 2 (April 2006) View Online Purchase This special issue of Forest Science showcases selected articles from the Second International Conference on Forest Measurements and Quantitative Methods and Management, which took place on June 15-18, 2004 at Hot Springs, Arkansas. The aim of this conference series is to conglomerate the diverse aspects of the quantitative methods used in forest inventory and management under a general umbrella of quantitative forestry. This collection includes articles on:
A valuable reference for inventory specialists, quantitative silviculturalists, quantitative ecologists, and biometricians. Sierran Mixed-Conifer Research Malcolm North and Jiquan Chen, editors Vol. 51, No. 3 (June 2005) View Online Purchase Many of the forests of the western United States have been severely altered by a century of fire suppression, prompting both regional and national restoration efforts. The success of these efforts requires a better understanding of past forest conditions and the ecological processes that affect forest health. This special issue of Forest Science, collected from a coordinated ecosystem-level experiment, investigates the connections between structure, composition, and function on 72 hectares of old-growth mixed-conifer in California's Sierra Nevada. Articles include:

Remote Sensing Randolph Wynne, Editor Vol. 49, No. 3 (June 2003) View Online Purchase Although remote sensing has been an integral part of forestry since the operational integration of aerial photographs into forest inventory in Canada in the 1920s, the rapid pace of sensor development and information needs in the past three decades has led to an explosion of forestry remote sensing research and applications. "Demands on forests are increasing and the information required to sustainably manage forests in the face of this demand must also increase," writes Randolph Wynne, associate professor of forestry at Virginia Tech and editor of the special issue. "Foresters are being asked to increase production of wood and fiber on an ever-decreasing land base while concomitantly maintaining the important supplies of public goods (viable fish and wildlife populations, clean water, and recreational opportunities) that well-managed forests have always provided. To meet this challenge, forest managers will require new types of information, and remote sensing will be an important piece of the overall information puzzle. The research results reported in this special issue of Forest Science will eventually lead to better information on, and therefore better management of, our forest resources." The papers in this special issue are a cross-section of the scope of data and applications in forestry remote sensing. Remotely sensed data types include aerial photographs, lidar data, hyperspectral images, radar data, and Earth resource satellite data. The data is being used for forest inventory, ecological land type delineation, harvest detection, chlorophyll mapping and monitoring, windthrow detection and mapping, and global forest cover mapping. Forest Wildlife-Habitat Relationships: Population and Community Responses to Forest Management Stephen DeStefano and Robert G.
