Book Description
Annual grass invasion in the Great Basin has increased fire size, frequency and severity. Post-fire restoration to provide functional native plant communities is critical to improve resistance to weed invasion. Our ability to successfully re-establish mixtures of native grasses, forbs and shrubs, however, is limited. We examined the effects of the standard rangeland drill and a minimum-till drill, seeding strategies for small-seeded species, and Wyoming big sagebrush (Artemisia tridentata Nutt. spp. wyomingensis Beetle & Young) seeding rates on seeding success in burned shrub communities at four sites in the northern Great Basin. Seeded and recovering vegetation, as well as soil physical and chemical characteristics, were monitored for two growing seasons following treatment. In addition, provision was made for long-term evaluation of grazed and non-grazed seedings to assess community dynamics in relation to management practices. Results underscore the impact of precipitation and recovering residual species on seeded species emergence and establishment. Emergence of drill seeded species was generally enhanced when seeded through the rangeland drill compared to the minimum-till drill, but this effect was lost by the second year. Wyoming big sagebrush emergence was erratic, but tended to be greater when seeded through the minimum-till drill at moderate or high rates (approximately 250 and 500 pure live seed m-2) compared to the low rate (50 pure live seed m-2). Cheatgrass and other exotics were reduced and basal gap lengths decreased where native seedings established or residual natives recovered, but both increased where seedings failed due to low precipitation. Considerable soil erosion occurred in burned areas, as indicated by dust production, soil stability, and soil microrelief. Fire substantially increased dust flux rates due to decreased soil stability; however, neither drill affected these processes. Amounts of soil movement via dust flux rates and changes in soil microrelief varied throughout seasons but were not affected by drilling. While wildfire altered some soil micronutrients, drilling and seeding rates did not alter chemical responses to fire. Further work is needed to link plant and soil responses, which may help to explain plant establishment after fire and seeding treatments. Vegetation data from this research will be archived in the USGS Land Treatment Digital Library to inform future management and rehabilitation programs.

Forest Landscape Restoration
Author: John StanturfPublisher: Springer Science & Business Media
ISBN: 9400753268
Category : Science
Languages : en
Pages : 322
Book Description
Restoration ecology, as a scientific discipline, developed from practitioners’ efforts to restore degraded land, with interest also coming from applied ecologists attracted by the potential for restoration projects to apply and/or test developing theories on ecosystem development. Since then, forest landscape restoration (FLR) has emerged as a practical approach to forest restoration particularly in developing countries, where an approach which is both large-scale and focuses on meeting human needs is required. Yet despite increased investigation into both the biological and social aspects of FLR, there has so far been little success in systematically integrating these two complementary strands. Bringing experts in landscape studies, natural resource management and forest restoration, together with those experienced in conflict management, environmental economics and urban studies, this book bridges that gap to define the nature and potential of FLR as a truly multidisciplinary approach to a global environmental problem. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.
Evaluating the Effectiveness of Postfire Rehabilitation Treatments

Book Description
Spending on postfire emergency watershed rehabilitation has increased during the past decade. A west-wide evaluation of USDA Forest Service burned area emergency rehabilitation (BAER) treatment effectiveness was undertaken as a joint project by USDA Forest Service Research and National Forest System staffs. This evaluation covers 470 fires and 321 BAER projects, from 1973 through 1998 in USDA Forest Service Regions 1 through 6. A literature review, interviews with key Regional and Forest BAER specialists, analysis of burned area reports, and review of Forest and District monitoring reports were used in the evaluation. The study found that spending on rehabilitation has increased to over $48 million during the past decade because the perceived threat of debris flows and floods has increased where fires are closer to the wildland-urban interface. Existing literature on treatment effectiveness is limited, thus making treatment comparisons difficult. The amount of protection provided by any treatment is small. Of the available treatments, contour-felled logs show promise as an effective hillslope treatment because they provide some immediate watershed protection, especially during the first postfire year. Seeding has a low probability of reducing the first season erosion because most of the benefits of the seeded grass occurs after the initial damaging runoff events. To reduce road failures, treatments such as properly spaced rolling dips, water bars, and culvert reliefs can move water past the road prism. Channel treatments such as straw bale check dams should be used sparingly because onsite erosion control is more effective than offsite sediment storage in channels in reducing sedimentation from burned watersheds. From this review, we recommend increased treatment effectiveness monitoring at the hillslope and sub-catchment scale, streamlined postfire data collection needs, increased training on evaluation postfire watershed conditions, and development of an easily accessible knowledge base of BAER techniques.

Author: Restoring forest landscapes through assisted natural regeneration (ANR) - A practical manual
Author: Food and Agriculture Organization of the United NationsPublisher: Food & Agriculture Org.
ISBN: 9251313822
Category : Nature
Languages : en
Pages : 55
Book Description
Case studies and experiences with natural regeneration from the region have shown that natural regeneration significantly reduces the cost of restoration in areas that meet certain conditions. Native species that are adapted to the prevailing conditions re-establish on their own with some assistance, achieving accelerated growth in accordance with natural succession, leading to the recovery of native ecosystems. Restoration strategies based on natural regeneration also provide low-cost opportunities for conserving biodiversity and enhancing ecosystem services, including carbon sequestration and watershed protection. This manual describes procedures from almost 20 years of FAO experience with assisted natural regeneration (ANR) in the Philippines and more recently in Indonesia, Cambodia and Lao PDR. In each of these countries, the method was applied for different objectives and convincingly validated ANR’s cost effectiveness. There is an increasing recognition of the benefits and advantages of ANR in light of the ambitious global, regional and national forest restoration targets, and there are considerable opportunities to expand the application of ANR through various restoration related initiatives. It is hoped that this manual can serve as a field reference in guiding the application of ANR for forest restoration.

Large-Scale Ecosystem Restoration
Author: Mary DoylePublisher: Island Press
ISBN: 1610910893
Category : Science
Languages : en
Pages : 345
Book Description
Large-Scale Ecosystem Restoration presents case studies of five of the most noteworthy large-scale restoration projects in the United States: Chesapeake Bay, the Everglades, California Bay Delta, the Platte River Basin, and the Upper Mississippi River System. These projects embody current efforts to address ecosystem restoration in an integrative and dynamic manner, at large spatial scale, involving whole (or even multiple) watersheds, and with complex stakeholder and public roles. Representing a variety of geographic regions and project structures, the cases shed light on the central controversies that have marked each project, outlining • the history of the project • the environmental challenges that generated it • the difficulties of approaching the project on an ecosystem-wide basis • techniques for conflict resolution and consensus building • the ongoing role of science in decision making • the means of dealing with uncertainties A concluding chapter offers a guide to assessing the progress of largescale restoration projects. Large-Scale Ecosystem Restoration examines some of the most difficult and important issues involved in restoring and protecting natural systems. It is a landmark publication for scientists, policymakers, and anyone working to protect or restore landscapes or watersheds.
