  • Native Orchids in Southeast Alaska
    Native Orchids in Southeast Alaska Marlin Bowles & Bob Armstrong 2019 Preface Southeast Alaska's rainforests, peatlands and alpine habitats support a wide variety of plant life. The composition of this vegetation is strongly influenced by patterns of plant distribution and geographical factors. For example, the ranges of some Asian plant species extend into Southeast Alaska by way of the Aleutian Islands; other species extend northward into this region along the Pacific coast or southward from central Alaska. Included in Southeast Alaska's vegetation are at least 27 native orchid species and varieties whose collective ranges extend from Mexico north to beyond the Arctic Circle, and from North America to northern Europe and Asia. These orchids survive in a delicate ecological balance, requiring specific insect pollinators for seed production, and mycorrhizal fungi that provide nutrients essential for seedling growth and survival of adult plants. These complex relationships can lead to vulnerability to human impacts. Orchids also tend to transplant poorly and typically perish without their fungal partners. They are best left to survive as important components of biodiversity as well as resources for our enjoyment. Our goal is to provide a useful description of Southeast Alaska's native orchids for readers who share enthusiasm for the natural environment and desire to learn more about our native orchids. This book addresses each of the native orchids found in the area of Southeast Alaska extending from Yakutat and the Yukon border south to Ketchikan and the British Columbia border. For each species, we include a brief description of its distribution, habitat, size, mode of reproduction, and pollination biology.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • 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. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Potrero Hills Landfill EIR EDAW Solano County 4.2-1 Biological Resources Proposed Phase II Expansion Area
    4.2 BIOLOGICAL RESOURCES The project applicant contracted with Environmental Stewardship & Planning, Inc. to conduct biological surveys for the Phase II Project, which is included as Appendix B. The biological surveys prepared by Environmental Stewardship & Planning, Inc. were reviewed by EDAW for consistency with industry-accepted standards. Based on this review and a site reconnaissance conducted by an EDAW biologist, the biological surveys were deemed to adequately characterize the existing biological resources on the project site and in the project vicinity. The information included in the biological surveys and supplemental biological data provide the basis for the analysis included in this section. 4.2.1 EXISTING CONDITIONS The project site is located in the secondary management area of the Suisun Marsh. It is a biologically diverse region that supports a varied assemblage of plant and wildlife species. The Potrero Hills are a series of steep, rolling hills that form an island of upland habitat almost completely surrounded by Suisun Marsh. Extensive areas of grazed grassland are located north of the site. GENERAL BIOLOGICAL RESOURCES Vegetation Currently Permitted Landfill The currently permitted 320-acre landfill is located in the central portion of the interior valley of the Potrero Hills in the secondary management area of the Suisun Marsh. The Potrero Hills are located about 5 miles east of downtown Fairfield, in Solano County, south of State Route (SR) 12. A large portion of the currently permitted landfill has been disturbed to accommodate existing landfill activities, and the remaining natural areas are dominated by non-native grassland habitat. Disturbed areas either are devoid of vegetation or support weedy vegetation, forming a ruderal habitat.

  • Wet Meadow Plant Associations, Malheur National Wildlife Refuge, Harney County, Oregon
    WET MEADOW PLANT ASSOCIATIONS, DOUBLE O UNIT, MALHEUR NATIONAL WILDLIFE REFUGE, HARNEY COUNTY, OREGON John A. Christy Oregon Biodiversity Information Center, Institute for Natural Resources Portland State University July 2016 Summary This report summarizes vegetation data collected in July 2015 in wet meadow and marshy habitats on the Double O Unit of Malheur National Wildlife Refuge (MNWR). Because vegetation sampled at the Double O was wetter and more alkaline than wet meadows sampled at the south end of the refuge in 2012 and 2013 (Christy 2014), data from the Double O Unit were analyzed and summarized separately. A total of 83 plots were sampled in 2015, and analysis of the data identified 14 plant associations: Alopecurus aequalis - Juncus balticus, Alopecurus pratensis - Potentilla anserina, Carex praegracilis - Juncus balticus, Cicuta douglasii - Carex nebrascensis, Distichlis spicata - Amphiscirpus nevadensis, Distichlis spicata - Nitrophila occidentalis, Eleocharis palustris - Juncus balticus, Eleocharis rostellata, Juncus balticus - Glaux maritima, Hippuris vulgaris - Triglochin maritima, Leymus triticoides - Juncus balticus, Schoenoplectus americanus, Spartina gracilis, and Triglochin maritima. Plant associations spanned a wetland gradient from seasonally moist to seasonally or perennially flooded, but surface water had left most stands at time of sampling. Mean Wetland Indicator Status scores and species composition help to place the plant associations within gradients in soil moisture and alkalinity. Seven of the 14 plant associations are listed in the International Vegetation Classification, and the remaining types are provisional. Acknowledgments Jess Wenick and Chad Karges of Malheur National Wildlife Refuge (MNWR) provided guidance, logistical support, and funding to The Wetlands Conservancy (TWC) for this project. Esther Lev of TWC coordinated the project and provided guidance as a member of the Ecology Woring Group (EWG).
