Synopsis Rule-based Mapping of Fire-adapted Vegetation and Fire Regimes for the Monongahela National Forest by : Melissa A. Thomas-Van Gundy

S2The use of prescribed fire is expected to increase as efforts to restore fire-dependent ecosystems gain momentum nationally. The documentation of historical fire regimes is essential for setting restoration objectives that include prescribed burning. To aid the Monongahela National Forest in this endeavor, a rule-based approach was employed in GIS to map fire-adapted vegetation and fire regimes. Spatial analyses and maps were generated using ArcMap 9.1 using the proclamation boundary of the Monongahela National Forest as our study area. Based on current knowledge of fire-vegetation-site relationships, we reviewed available data sets for relevancy in estimating fire regimes. Four themes were selected: land type association, potential natural vegetation (primary and secondary), and current forest type. All themes were converted to 20 m2 grids. Selected features of each theme were scaled from 1 through 5 according to their relationship to fire, with 1 representing conditions most conducive to fire and 5 the least. Each theme was weighted to reflect its inferred effect on system fire adaptation. The resulting fire adaptation scores were then categorized into standard fire regime groups. Fire regime group V (200+ yrs fire frequency) was the most common, assigned to more than 510,000 ha, primarily in the Allegheny Mountains Section. Fire regime group I (low & mixed severity, 0- 35 yrs) and III (low & mixed severity, 35 -200 yrs) were assigned to nearly 198,000 ha, primarily in the Ridge and Valley Section and one subsection within the Allegheny Mountains Section. The resultant maps are intended to identify fire-adapted systems for land management purposes. These systems likely will require active silviculture using fire and/or fire surrogates for their maintenance or restoration. The transparent rule-based procedure can be easily modified and, as such, possesses the flexibility for application to other ecosystems with similar spatial databases. S3.

Synopsis Seed Bank Response to Prescribed Fire in the Central Appalachians by :

Pre- and post-treatment seed-bank characteristics of woody species were compared after two prescribed fires in a mesic mixed-oak forest in the central Appalachians. Nineteen woody species were identified from soil samples. Mean species richness declined but evenness did not after prescribed burning. The seed bank was dominated by black birch, yellow-poplar, blackberry, grapevine and Hercules club before burning. Following burning, the median density of seed bank propagules declined by 45 percent. Black birch, yellow-poplar, and grapevine declined by 69, 56, and 40 percent, respectively. The results illustrate the importance of the seed bank as a robust source of non-oak regeneration in mixed-oak forests and of the potential effect of fire altering it.

Synopsis Federal Wildland Fire Management by : DIANE Publishing Company

Managing wildland fire in the U.S. is a challenge increasing in complexity & magnitude. The goals & actions presented in this report encourage a proactive approach to wildland fire to reduce its threat. Five major topic areas on the subject are addressed: the role of wildland fire in resource management; the use of wildland fire; preparedness & suppression; wildland/urban interface protection; & coordinated program management. Also presented are the guiding principle that are fundamental to wildland fire management & recommendations for fire management policies. Photos, graphs, & references.

Synopsis Natural Disturbances and Historic Range of Variation by : Cathryn H. Greenberg

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.

Synopsis Forest and Rangeland Soils of the United States Under Changing Conditions by : Richard V. Pouyat

This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.

Synopsis Compensating for Wetland Losses Under the Clean Water Act by : National Research Council

Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.

Synopsis Ohio Forests, 2006 by : Richard H. Widmann

This report summarizes annual forest inventories conducted in Ohio from 2001 to 2006 by the Northern Research Station's Forest Inventory and Analysis unit. Ohio's forest land covers 7.9 million acres or 30 percent of the State's land area, changing little in forest land area since 1991. Of this land, 5.8 million acres (73 percent) are held by family forest owners. The current growing-stock inventory is 12.3 billion cubic feet--2 percent more than in 1991--and averages 1,603 cubic feet per acre. Yellow-poplar continues to lead in volume followed by red and sugar maples. Since 1991, the saw log portion of growing-stock volume has increased by 35 percent to 41 billion board feet. In the latest inventory, net growth exceeded removals for all major species except elm.
