  • "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.

  • P L a N T L I S T Water-Wise Trees and Shrubs for the High Plains
    P L A N T L I S T Water-Wise Trees and Shrubs for the High Plains By Steve Scott, Cheyenne Botanic Gardens Horticulturist 03302004 © Cheyenne Botanic Gardens 2003 710 S. Lions Park Dr., Cheyenne WY, 82001 www.botanic.org The following is a list of suitable water-wise trees and shrubs that are suitable for water- wise landscaping also known as xeriscapes. Many of these plants may suffer if they are placed in areas receiving more than ¾ of an inch of water per week in summer. Even drought tolerant trees and shrubs are doomed to failure if grasses or weeds are growing directly under and around the plant, especially during the first few years. It is best to practice tillage, hoeing, hand pulling or an approved herbicide to kill all competing vegetation for the first five to eight years of establishment. Avoid sweetening the planting hole with manure or compost. If the soil is needs improvement, improve the whole area, not just the planting hole. Trees and shrubs generally do best well with no amendments. Many of the plants listed here are not available in department type stores. Your best bets for finding these plants will be in local nurseries- shop your hometown first! Take this list with you. Encourage nurseries and landscapers to carry these plants! For more information on any of these plants please contact the Cheyenne Botanic Gardens (307-637-6458), the Cheyenne Forestry Department (307-637-6428) or your favorite local nursery.

  • Northstar Fire Department, Fire Resistant Landscaping Plant List
    Northstar Fire Department, Fire Resistant Landscaping Plant List Many common plants naturally resist fire and can even slow its spread. In general, irrigated and well maintained leafy plants burn slowly. By replacing highly flammable vegetation with these fire resistant recommended species, you can significantly improve the statistical survivability of your home when a wildfire threatens. Courtesy of the “Villager Nursery” in Truckee, this list of fire resistive plants should be considered when enhancing or adding landscape. Here are some other key components to remember when selecting appropriate fire resistant landscaping plants. Choose plants that don’t produce much litter such as dead branches and twigs Plants that produce oils, resins or waxes should be avoided When planting from the approved list, appropriately space plants to prevent fire spread Never plant under conifer trees, this can create a ladder effect which allows smaller ground fires the ability to transfer into larger trees creating crown fires To help ensure their fire resistance, plants must be maintained, watered, and pruned. Routine care will provide you with an attractive defensible space landscape and help ensure the survival of your property in the event of a wildfire. Northstar Fire Department enforces both State and District fire codes that may directly affect your landscape. Northstar Fire Department recommends that prior to changing your landscape you consult with us in order to make sure your property will be compliant with applicable fire codes.

The mpI ortance of Geographic and Biological Variables in Predicting the Naturalization of Non-Native Woody Plants in the Upper Midwest Abstract The es lection, introduction, and cultivation of non-native woody plants beyond their native ranges can have great benefits, but also unintended consequences. Among these consequences is the tendency for some species to naturalize and become invasive pests in new environments to which they were introduced. In lieu of lengthy and costly field trials, risk-assessment models can be used to predict the likelihood of naturalization.

Here we investigate whether such heat treatment leads to the accumulation of sequence variability in HLVd. We observed a negligible level of mutated variants in HLVd under standard cultivation conditions. In contrast, the heat treatment of hop led to HLVd degradation and, simultaneously, to a significant increase in sequence variations, as judged from temperature gradient–gel electrophoresis analysis and cDNA library screening by DNA heteroduplex analysis. Thirty-one cDNA clones (9.8%) were identified as deviating forms.

  • CDFG Natural Communities List
    Department of Fish and Game Biogeographic Data Branch The Vegetation Classification and Mapping Program List of California Terrestrial Natural Communities Recognized by The California Natural Diversity Database September 2003 Edition Introduction: This document supersedes all other lists of terrestrial natural communities developed by the Natural Diversity Database (CNDDB). It is based on the classification put forth in “A Manual of California Vegetation” (Sawyer and Keeler-Wolf 1995 and upcoming new edition). However, it is structured to be compatible with previous CNDDB lists (e.g., Holland 1986). For those familiar with the Holland numerical coding system you will see a general similarity in the upper levels of the hierarchy. You will also see a greater detail at the lower levels of the hierarchy. The numbering system has been modified to incorporate this richer detail. Decimal points have been added to separate major groupings and two additional digits have been added to encompass the finest hierarchal detail. One of the objectives of the Manual of California Vegetation (MCV) was to apply a uniform hierarchical structure to the State’s vegetation types. Quantifiable classification rules were established to define the major floristic groups, called alliances and associations in the National Vegetation Classification (Grossman et al. 1998). In this document, the alliance level is denoted in the center triplet of the coding system and the associations in the right hand pair of numbers to the left of the final decimal. The numbers of the alliance in the center triplet attempt to denote relationships in floristic similarity. For example, the Chamise-Eastwood Manzanita alliance (37.106.00) is more closely related to the Chamise- Cupleaf Ceanothus alliance (37.105.00) than it is to the Chaparral Whitethorn alliance (37.205.00).

  • Fire-Resistant Plants for Oregon Home Landscapes
    FFire-ire-RResistantesistant PlantsPlants forfor OregonOregon HomeHome LandscapesLandscapes Suggesting specific types of vegetation that may reduce your risk from wildfire. Stephen Fitzgerald Area Extension Forester and Associate Professor Amy Jo Waldo Area Extension Horticulture Agent and Assistant Professor OSU Extension Service 1421 S. Hwy 97, Redmond, OR 97756 Introduction Oregon has many wildfire prone areas. In these places, fires are a natural part of the changing landscape. As homes are built in these areas, special precautions must be taken by the homeowner to pro- tect their property. Installation of fire- resistive roofing is critical to preventing firebrands from igniting the home from a roof fire. Well maintained fire-resistant vegetation and irrigated landscape is also critical within close proximity of a home. These actions DO NOT insure that your home will survive a wildfire, but they provide for a good chance of structural survival. Implementation of FireFree [www.firefree.org] and FireWise [www.firewise.org] activities can also significantly improve chances of a home surviving a wildfire. Fire-resistant vegetation. When landscaping around a home, most homeowners are interested in creating a landscape that is aesthetically pleasing, compliments their home, and has varia- tions in color, texture, flowers, and foliage. If your home is located in or adjacent to forests or rangeland, you should also consider the flammability of plants within your home landscape. Flammable plant material in your land- scape can increase the fire-risk around your home. The 1991 Oakland Hills Fire in California is a prime example of how flam- mable plant material (Eucalyptus trees) can act as fuel and contribute to the inten- sity of a wildfire.
