Steward started work on vegetative keys to the aquatic plants of thePa- cific Northwest ; his untimely death in June of 1959 made it necessaryfor as- sociate authors to be named to continue the project. The area included in this study is Oregon, Washington, British Colum- bia, and Alaska. Considerable difficulty was encountered in preparing alist of plants to be included. An effort was made to include all true aquatics andalso species whose life cycle includes some stage that requires either the saturation of the substrate with water or the presence of an ambient aqueousmedium. The intent has been to exclude species occasionally found in moist places but equally at home in drier situations. In the Pacific Northwest the period of flowering and fruiting of aquatic plants is very short when compared to the long period of vegetative develop- ment experienced by a large proportion of the species.Many species appear not to flower every year but may appear prominently in the floravegetatively for ten to twelve months of each year. This situation makes it mostdesirable that the keys be constructed primarily upon vegetative characters.This has been the approach wherever possible in this study. Reproductive characters have often been given as secondary characteristics to supplementand strengthen the keys. Where species are not readily distinguishable vegetatively, inserts were made in the key making separations on reproductive characters. Numerous individuals have helped in the preparation of this manuscript ; to them the authors express their genuine appreciation.Special mention should be made of the National Science Foundation for making the studyfinancially possible; Dr. Roy A. Young, head of the Department of Botanyand Plant Pathology for encouragement and consideration; Dr. Harry K. Phinneyfor advanced testing of the key to families in his class and for valuable sugges- tions; Dr. Frank H. Smith for critical editorial and technical assistance;and Mrs. Catherine Davis Young for most of the detailed drawings.

  • "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.

This booklet was prepared with funds from the Forest Service Celebrating Wildflowers program, whose goals are to serve our nation by introducing the American public to the aesthetic, recreational, biological, ecological, medicinal, and economic values of our native botanical resources. By becoming more thoroughly acquainted with local plants and their multiple values, we hope to consequently in- crease awareness and understanding of the Forest Service’s management undertakings regarding plants, including our rare plant conservation programs, invasive plant man- agement programs, native plant materials programs, and botanical research initiatives. This booklet is a trial booklet whose purpose, as part of the Celebrating Wildflowers program (as above explained), is to increase awareness of local plants. The Modoc NF Botany program earnestly welcomes your feedback; whether you found the book help- ful or not, if there were too many plants represented or too few, if the information was useful to you or if there is more useful information that could be added, or any other comments or concerns. Thank you. Forest J. R. Gauna Asst.

  • Ventura County Plant Species of Local Concern
    Checklist of Ventura County Rare Plants (Twenty-second Edition) CNPS, Rare Plant Program David L. Magney Checklist of Ventura County Rare Plants1 By David L. Magney California Native Plant Society, Rare Plant Program, Locally Rare Project Updated 4 January 2017 Ventura County is located in southern California, USA, along the east edge of the Pacific Ocean. The coastal portion occurs along the south and southwestern quarter of the County. Ventura County is bounded by Santa Barbara County on the west, Kern County on the north, Los Angeles County on the east, and the Pacific Ocean generally on the south (Figure 1, General Location Map of Ventura County). Ventura County extends north to 34.9014ºN latitude at the northwest corner of the County. The County extends westward at Rincon Creek to 119.47991ºW longitude, and eastward to 118.63233ºW longitude at the west end of the San Fernando Valley just north of Chatsworth Reservoir. The mainland portion of the County reaches southward to 34.04567ºN latitude between Solromar and Sequit Point west of Malibu. When including Anacapa and San Nicolas Islands, the southernmost extent of the County occurs at 33.21ºN latitude and the westernmost extent at 119.58ºW longitude, on the south side and west sides of San Nicolas Island, respectively. Ventura County occupies 480,996 hectares [ha] (1,188,562 acres [ac]) or 4,810 square kilometers [sq. km] (1,857 sq. miles [mi]), which includes Anacapa and San Nicolas Islands. The mainland portion of the county is 474,852 ha (1,173,380 ac), or 4,748 sq.
