Rentch, West Virginia University Thomas M. Schuler, U.S. Forest Service Sponsored by: The Nature Conservancy U.S. Forest Service, Northern Research Station and the Monongahela National Forest West Virginia University, Division of Forestry and Natural Resources U.S. Fish and Wildlife Service Snowshoe Mountain Resort West Virginia Highlands Conservancy Foreword The Conference on the Ecology and Management of High Elevation Forests in the Central and Southern Appalachians was conceived to bring together managers, practitioners, and researchers working to better understand the unique issues relevant to high-elevation forests in the central and southern Appalachians. We invited Charles Cogbill (Harvard Forest) to summarize the biogeography of high-elevations forests in the central and southern Appalachians, Carolyn Copenheaver (Virginia Tech) to provide insight into the historical conditions of high-elevation forests in the region, Greg Nowacki (U.S. Forest Service) to summarize the current state of the forest, and Mark Anderson (The Nature Conservancy) to address how climate change may influence these forests in the future. The conference also consisted of 42 offered oral presentations and 14 posters. Concurrent sessions were organized to cover topics relevant to acid deposition and nutrient cycling, ecological classification and forest dynamics, avifauna, wildlife and fisheries, forests pests and climate change, and regeneration and restoration. A plenary session was also devoted to a panel discussion to highlight the efforts of the informally chartered High Elevation Conservation Working Group and to invite new cooperators to this multi-partner initiative. The conference concluded with a field trip to Snowshoe Mountain Resort sites that exemplified conservation issues relevant to high- elevation wetlands, the recently delisted West Virginia northern flying squirrel, the threatened Cheat Mountain salamander, silvicultural options for active restoration of high-elevation forests, and soil characteristics unique to high-elevation spruce forests not impacted by high-intensity wildfires. Interest in continuing this conference on a reoccurring basis was expressed by many in attendance. Steering Committee: W.

The Steering Committee also thanks Nathan Beane, Elizabeth Tinchner, and Brittany Johnson for their contributions during the conference. Review Procedures Manuscripts for oral presentations were assigned to one of the editors and peer-reviewed by at least two reviewers assigned by the editors. Reviews were returned to editors, summarized, and sent to the authors with recommendations. Authors revised their manuscripts and returned them to the editors. Revised manuscripts were then reviewed again by the editors and once finalized, were submitted to the Northern Research Station, U.S. Forest Service for final editing and publishing.

    West Virginia Northern Flying Squirrel (WVNFS), Glauconzys Sabrinus Fuscus Five Year Status Review Appendix B — Capture Site Summaries

    U.S. Fish and Wildlife Service — West Virginia Field Office West Virginia northern flying squirrel (WVNFS), Glauconzys sabrinus fuscus Five Year Status Review Appendix B — Capture Site Summaries Attached are the summaries for the 105 West Virginia northern flying squirrel (WVNFS), G.s. fuscus, capture sites l in West Virginia. Although biologists occasionally use live-trapping, nest boxes have been the primary tool for population surveys for the WVNFS. Biologists place transects of nest boxes in a survey area and check the boxes periodically for occupancy, typically twice each year, in fall and spring. Northern flying squirrels are nocturnal, leaving their nests to forage at night and returning during the day, which facilitates daytime nest box monitoring. The success of nest box monitoring relies on the squirrels occupying the boxes during the day of the survey. Menzel (2003) found that no WVNFS in her radio telemetry study used nest boxes (despite their availability) as den sites. All nests were either natural tree cavities (i.e. dens) or dreys (i.e. outside nests constructed of leaves, twigs, lichens, etc.). She also noted WVNFS used multiple den sites, switching nests on average every 3 days in summer, and utilizing up to 12 den sites per month in lesser quality habitat (Menzel 2000, Menzel et al. 2004). Further, the nest box monitoring program conducted by the DNR had a 2% average success rate of squirrel occupancy per box checked. These data confirm the difficulty of capturing squirrels via nest boxes and caution against relying on nest box survey results to determine occupied habitat, i.e., although a captured individual affirms presence, an empty nest box does not necessarily signify absence or unoccupied habitat.

    Monongahela National Forest Administrative Correction 15 August 12, 2010 Changes to Management Prescription 8.2 Areas Due to New Information Under the 2000 Planning Rule (36 CFR 219.31), the following administrative corrections and additions may be made at any time, are not plan amendments or revisions, and do not require public notice or the preparation of an environmental document under Forest Service NEPA procedures: (1) Corrections and updates of data and maps; (2) Updates to activity lists and schedules as required by § 219.30(d)(1)-(6); (3) Corrections of typographical errors or other non-substantive changes; and (4) Changes in monitoring methods other than those required in a monitoring strategy. The following corrections are a result of new information from the USDI National Park Service about National Natural Landmarks (NNLs) on the Monongahela National Forest (MNF). During a recent visit to inspect NNLs on the MNF, Carolyn Davis of the NPS compared her list of NNLs on the Forest to the Forest Ecologist’s list, and two discrepancies were found. First, the Falls of Hills Creek area was not on the NPS list as an NNL. Second, the Germany Valley Karst Area was on the NPS list but not on the MNF list of NNLs. Therefore, the following administrative corrections are being made to NNLs, which are identified as Management Prescription 8.2 in the MNF Forest Plan. All acreage figures have been rounded off to the nearest 10 acres. CORRECTIONS Forest Plan Chapter III, page III-40 (originally page III-46) MP 8.0 Special Area Table, seventh

Nevertheless, trunks of A. pensylvanicum as they approach common names can offer intriguing clues about the rutting season, suggesting two additional plants and their formal, natural, and historical common names—moose maple and moose- associations.

    Northern Hardwoods – Hemlock – White Pine Forest

    Classification of the Natural Communities of Massachusetts Terrestrial Communities Descriptions Northern Hardwoods – Hemlock – White Pine Forest Community Code: CT1C000000 State Rank: S5 Concept: A matrix forest of northern areas, with a closed canopy dominated by a mix of deciduous and evergreen trees, with sparse shrub and herbaceous layers. Environmental Setting: The Northern Hardwoods - Hemlock - White Pine Forest is the prevailing, or matrix, forest in higher elevations of western and north-central Massachusetts, with smaller occurrences throughout on north-facing slopes and in ravines. It is an uneven-aged forest with a closed canopy dominated by a mix of long-lived deciduous and evergreen trees, with sparse shrub and herbaceous layers. The forest structure is dominated by single tree falls and replacements, with occasional small to medium blowdown events; stand replacement events are uncommon. The community occurs on neutral to moderately acidic soils with moderate levels of nutrients that retain some moisture except during extreme droughts. Sugar maple leaf litter is relatively high in nitrogen and decomposes rapidly which leads to a shallow layer of leaf litter and rapid turnover of nutrients. Vegetation Description: Dominant and characteristic species of Northern Hardwoods - Hemlock - White Pine Forests occur in different combinations between and within occurrences: occurrences are generally predominantly deciduous with scattered hemlocks and white pines, but may have internal patches of nearly pure conifers. Canopies include variable combinations of sugar maple (Acer saccharum), white ash (Fraxinus americana), yellow birch (Betula alleghaniensis), American beech (Fagus grandifolia), black cherry (Prunus serotina), red oak (Quercus rubra), bitternut hickory (Carya cordiformis), eastern hemlock (Tsuga canadensis), and, usually, emergent white pine (Pinus strobus).
