    "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. CODE KEY- The code key below will assist you in selecting for appropriate characteristics.

Naturforsch. 59c, 459Ð462 (2004); received April 26/May 13, 2004 Leaf glands of Ceanothus species excrete a lipophilic material that contains a variety of flavonoids. Most of these are aglycones, but some glycosides were also observed. Seven out of eight species exhibit flavonols, whereas flavones are excreted by only one species. Four species produce flavanones and dihydroflavonols; one excretes a remarkable quantity of fla- vonol glycosides. The exudate flavonoids thus form different patterns that might be charac- teristic for different Ceanothus species.

    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. Trees Common Name Scientific Name Please note that there Apple Malus spp. may be other vegetative Bigtooth Maple Acer grandidentatum species that are Cherry Prunus spp.
  • CDFG Natural Communities List

    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).
  • Native Or Suitable Plants City of Mccall

    Native Or Suitable Plants City of Mccall

    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring.
