Final Environmental Assessment for Land Management Final Environmental Assessment for Land Management National Conservation Training Center United States Fish and Wildlife Service Shepherdstown, West Virginia February 2011 Note to Readers This Final Environmental Assessment for Land Management at the National Conservation Training Center contains changes that reflect public comments on the draft environmental assessment (EA). One significant change made in response to comments was to reconsider prescribed burning in woodland areas as a possible activity. This was previously discussed as a possibility and had been included in the effects analysis, but did not appear in the Alternative C discussion in the draft EA under “Proposed Activity 3—Use prescribed fire to control or suppress invasive/exotic plant species and reduce ground and ladder fuels.” The effects analysis for this proposed activity was also re- inserted into the “Habitat and Wildlife” section of chapter 3; however, the draft EA did contain discussions of the effects of prescribed fire on the other resource topics. Other changes include more emphasis on wildfire as a potentially destructive force, as well as the potential beneficial effects of fire. NATIONAL CONSERVATION TRAINING CENTER FINAL ENVIRONMENTAL ASSESSMENT FOR LAND MANAGEMENT Lead Agency: Department of the Interior U.S. Fish and Wildlife Service Responsible Official: Mr.JamesSlack,NCTCDirector For Information Contact: Mr. Phil Pannill, NCTC Land Manager [email protected] The United States Fish and Wildlife Service (FWS) has prepared this environmental assessment for the National Conservation Training Center (NCTC) to present various management strategies to control invasive plant species, promote the growth of native plants, control other pests, and prepare for a potential wildfire. The FWS is proposing various treatment methods (such as manual, mechanical, biological, cultural, chemical, and prescribed fire) to achieve management objectives. Alternative A: No Action—Continue Current Level of Land Management The no-action alternative for this EA is described as continuation of the current level of management. Grassland Areas. The overall management objective for grassland habitat (other than areas planned for reforestation) is to restore the former agricultural fields to a native grassland biological community to provide optimum feeding, breeding, and wintering habitat for a diversity of grassland- dependent migratory birds, native pollinating invertebrates, and other native wildlife that are present. This would be accomplished through continued haying, mowing, planting desired species, and chemically treating undesirable species. Mixed-deciduous Forest Areas. The overall management objective for the forest areas is to protect or re-establish desired species, eradicate undesirable species, and protect forested areas from unplanned ignitions. This would be accomplished through re-establishing desired species and chemically treating undesirable species Wetland/Riparian Areas. The overall management objective for riparian/wetland areas is to protect, maintain, and enhance the biological diversity of riparian/wetland areas. This would be accomplished through planting desired species and chemically treating undesirable species. Alternative B: Cease All Land Management Activities This alternative proposes that the NCTC would stop all land management actions—this includes mowing, haying, planting desired species, and chemically treating undesirable species. Alternative C: Proposed Action (Preferred Alternative) The same management actions (except haying) that would continue under Alternative A would also continue under Alternative C. The new proposed activities under Alternative C are the use of prescribed fire to control weeds and woody vegetation, over time, and reduce litter buildup (ground fuels) and ladder fuels; and actions to control “other pests.” The overall management objectives for controlling other pests are to prevent unacceptable damage or impediment to forests, grasslands, and riparian areas; habitat restoration sites; landscaped areas; and roads, sidewalks, trails, fences, buildings, and other facilities; protect human health and ensure the safety of workers, staff, and guests; and protect habitat and other environmental factors in the process of conducting control measures. This would be accomplished through use of cultural and mechanical controls and chemically treating undesirable species. iii U.S. Fish and Wildlife Service Final EA for Land Management Table of Contents Chapter 1.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

(2005): Central European genera of the Boletaceae and Suillaceae, with notes on their anatomical characters. - Czech Mycol. 57: 1-50. A taxonomic survey of Central European genera of the families Boletaceae and Suillaceae with tubular hymenophores, including the lamellate Phylloporus, is presented. Questions concerning the delimitation of the bolete genera are discussed. Descriptions and keys to the families and genera are based predominantly on anatomical characters of the carpophores. Attention is also paid to peripheral layers of stipe tissue, whose anatomical structure has not been sufficiently studied. The study of these layers, above all of the caulohymenium and the lateral stipe stratum, can provide information important for a better understanding of relationships between taxonomic groups in these families. The presence (or absence) of the caulohymenium with spore-bearing caulobasidia on the stipe surface is here considered as a significant ge­ neric character of boletes. A new combination, Pseudoboletus astraeicola (Imazeki) Šutara, is proposed. Key words: Boletaceae, Suillaceae, generic taxonomy, anatomical characters. Šutara J.

  • Chapter 2 Literature Review
    CHAPTER 2 LITERATURE REVIEW 2.1. BASIDIOMYCOTA (MACROFUNGI) Representatives of the fungi sensu stricto include four phyla: Ascomycota, Basidiomycota, Chytridiomycota and Zygomycota (McLaughlin et al., 2001; Seifert and Gams, 2001). Chytridiomycota and Zygomycota are described as lower fungi. They are characterized by vegetative mycelium with no septa, complete septa are only found in reproductive structures. Asexual and sexual reproductions are by sporangia and zygospore formation respectively. Ascomycota and Basidiomycota are higher fungi and have a more complex mycelium with elaborate, perforate septa. Members of Ascomycota produce sexual ascospores in sac-shaped cells (asci) while fungi in Basidiomycota produce sexual basidiospores on club-shaped basidia in complex fruit bodies. Anamorphic fungi are anamorphs of Ascomycota and Basidiomycota and usually produce asexual conidia (Nicklin et al., 1999; Kirk et al., 2001). The Basidiomycota contains about 30,000 described species, which is 37% of the described species of true Fungi (Kirk et al., 2001). They have a huge impact on human affairs and ecosystem functioning. Many Basidiomycota obtain nutrition by decaying dead organic matter, including wood and leaf litter. Thus, Basidiomycota play a significant role in the carbon cycle. Unfortunately, Basidiomycota frequently 5 attack the wood in buildings and other structures, which has negative economic consequences for humans. 2.1.1 LIFE CYCLE OF MUSHROOM (BASIDIOMYCOTA) The life cycle of mushroom (Figure 2.1) is beginning at the site of meiosis. The basidium is the cell in which karyogamy (nuclear fusion) and meiosis occur, and on which haploid basidiospores are formed (basidia are not produced by asexual Basidiomycota). Mushroom produce basidia on multicellular fruiting bodies.

Victoroff A thesis submitted in partial fulfillment of the requirements for the Master of Science Degree State University of New York College of Environmental Science and Forestry Syracuse, New York Department of Environmental and Forest Biology Approved by: Thomas R. Horton, Major Professor Theodore Dibble, Examining Committee Chairperson Melissa Fierke, Department Chairperson S. Scott Shannon, Dean, the Graduate School Acknowledgments Throughout the course of my master’s I have benefitted from the support of my lab mates, friends, and loved ones. I owe so much to my mentor Dr. Tom Horton. Tom has helped me to grow into a scientist. I entered ESF the summer after finishing my undergraduate and Tom’s guidance has helped me to develop away from insecurity and (closer) to self-directedness. The lab culture that Tom inspires is a cooperative and productive work environment and I am so thankful that I was able to be a part of it. The ESF community is unique. The curious minds of the undergraduates have inspired me, and the expertise of the faculty has challenged and motivated me. I have been supported through teaching assistantships by Tom (EFB 320 General Ecology Laboratory) and by Dr. Stewart Diemont (EFB 120 Global Environments Lecture). Tom and Stew have been excellent role models for me to adapt my own teaching style from. I am thankful for my graduate committee. Together my committee has directed my research and each member has benefitted my academic career significantly.

JOHN HAYDEN Department of Biology, University of Richmond, Richmond, Virginia 23173 ABSTRACT The genus Penthorum L. consists of two species of perennial herbs, P. sedoides of eastern North America and P. chinense ofeastern Asia. Pentho rum has long been considered intermediate between Crassulaceae and Saxifragaceae. An anatomical study of both species was undertaken to contribute to a better understanding of the relationships ofthese plants. Prominent anatomical features of Penthorum include: an aerenchymatous cortex and closely-spaced collateral vascular bundles of stems; one-trace unilacunar nodes; brochidodromous venation, rosoid teeth bearing hydathodes, and anomocytic stomata of leaves; angular vessel elements with many-barred scalariform perforation plates and alternate to scattered intervascular pits; thin-walled non­ septate fiber-tracheids; abundant homocellular erect uniseriate and biseriate rays; and absence of axial xylem parenchyma.
