"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. -
Research Reports Response of Five Hydrangea Species to Foliar Salt Spray1
Research Reports Response of Five Hydrangea Species to Foliar Salt Spray1 N. Barbara Conolly2, Nina L. Bassuk3, and Patrick F. MacRae Jr.4 Urban Horticulture Institute, Department of Horticulture Cornell University, Ithaca, NY 14853 Abstract Hydrangeas are popular seaside plants; however, other than in anecdotal reports, there are no studies measuring their relative tolerance to salt spray. We examined response of ten cultivars and one subspecies of Hydrangea representing fi ve species to foliar-applied salt solutions to recommend selections for seaside landscapes. Objectives were to determine whether there are differences in responses to salt spray among cultivars and species, and to determine whether varying concentrations of sodium chloride differentially damaged the plants. Plants were treated with a full-strength (ion concentration approximate to seawater) salt solution, a half-strength salt solution, or a control of tap water. Plants were rated after seven once-weekly applications based on percentage necrotic leaf area, an aesthetically and physiologically important symptom of damage. Cultivars of Hydrangea macrophylla and Hydrangea serrata were more tolerant of full-strength salt spray than cultivars of H. paniculata, H. anomala and H. arborescens. At half strength but not full strength, H. anomala ssp. petiolaris was most tolerant. Hydrangea macrophylla and H. serrata were the second most tolerant of half-strength applications. Hydrangea macrophylla or Hydrangea serrata should be planted where maritime salt spray will occur. Index words: seawater aerosol, NaCl, Hydrangeaceae. Species used in this study: Smooth hydrangea (Hydrangea arborescens L.) cultivars ‘Annabelle’, ‘Dardom’ White Dome®, ‘Hayes Starburst’; bigleaf hydrangea (Hydrangea macrophylla (Thunb.) Ser.) cultivars ‘Paris’ (Cityline™ series), ‘Nikko Blue’, ‘All Summer Beauty’; panicle hydrangea (Hydrangea paniculata Sieb.) cultivars ‘Limelight’, ‘Tardiva’; Hydrangea serrata (Thunb.) Ser. -

Trees, Shrubs, and Perennials That Intrigue Me (Gymnosperms First
Big-picture, evolutionary view of trees and shrubs (and a few of my favorite herbaceous perennials), ver. 2007-11-04 Descriptions of the trees and shrubs taken (stolen!!!) from online sources, from my own observations in and around Greenwood Lake, NY, and from these books: • Dirr’s Hardy Trees and Shrubs, Michael A. Dirr, Timber Press, © 1997 • Trees of North America (Golden field guide), C. Frank Brockman, St. Martin’s Press, © 2001 • Smithsonian Handbooks, Trees, Allen J. Coombes, Dorling Kindersley, © 2002 • Native Trees for North American Landscapes, Guy Sternberg with Jim Wilson, Timber Press, © 2004 • Complete Trees, Shrubs, and Hedges, Jacqueline Hériteau, © 2006 They are generally listed from most ancient to most recently evolved. (I’m not sure if this is true for the rosids and asterids, starting on page 30. I just listed them in the same order as Angiosperm Phylogeny Group II.) This document started out as my personal landscaping plan and morphed into something almost unwieldy and phantasmagorical. Key to symbols and colored text: Checkboxes indicate species and/or cultivars that I want. Checkmarks indicate those that I have (or that one of my neighbors has). Text in blue indicates shrub or hedge. (Unfinished task – there is no text in blue other than this text right here.) Text in red indicates that the species or cultivar is undesirable: • Out of range climatically (either wrong zone, or won’t do well because of differences in moisture or seasons, even though it is in the “right” zone). • Will grow too tall or wide and simply won’t fit well on my property. -

Threatened Lilies Reach for the Sky
Threatened Lilies Reach for the Sky I was thinking the other day about an old friend, conservationist Rusty Walton, who passed away last year. To say he was quiet would be an understatement. I could rarely make a smile bend on his face no matter how hard I tried. However, as I think back on the times I spent with him it always makes me smile. He was a dedicated naturalist and an accomplished ecologist. He introduced me to my first wild patch of wood lily on the Vineyard almost ten years ago. Recently I went back to the same spot, and surprisingly the lilies, like Rusty were gone. The wood lily (Lilium philadelphicum) has been drastically reduced on the Vineyard by large populations of deer. Wood lily has a natural distribution range across thirty seven US states. However similar to here on the Vineyard, they are losing ground across North American due to the over population of deer. Frequently I am asked about what it means when a plant goes extinct. On the Vineyard I am talking about “local” extinction, not the complete loss of a species from our planet. The underlying tragedy of local species extinction is the loss of the co-dependent species that have formed a mutualistic (beneficial) relationship with plants. These species include its insect pollinators that use it as a nectar source, and insects that may also feed on parts of the plant or lay their eggs on it to support their lifecycle. The dependence goes further with the birds that feed on those insects. -

Voor gebruik in de openbare ruimte zouden ze minder geschikt zijn omdat ze te veel water, voeding en onderhoud zouden vragen. Volgens de experts berust dit echter op een misverstand.
