Louise Gronmyr typed most of the contributions and helped in many ways in the production of the final manuscript which was typeset by Beth Collins. Denise Manning proofed the final document. We are thankful to the curators and staff of the following institutions for allowing us to study their collections and use their facilities: National Herbarium, National Museums, Ottawa (CAN); Herbarium, Royal British Columbia Museum, Victoria (V); Vascular Plant Herbarium, Department of Agriculture, Ottawa (DAO); Herbarium, Department of Botany, University of British Columbia, Vancouver (UBC); Herbarium, Department of Biology, University of Victoria (UVIC); Herbarium, Department of Botany, University of Toronto (TRT). iv SEQ 6168 JOB VASC-002-012 PAGE-0001 COMMON NAMES REVISED 31JUL00 AT 08:32 BY BC DEPTH: 62 PICAS WIDTH 44 PICAS COLOR LEVEL 1 INTRODUCTION This manual describes all of the flowering plants and vascular cryptogams, both native and naturalized, occurring within the borders of British Columbia. Keys are included for all genera, species, subspecies and varieties. The study is based on examination of specimens in all major Canadian herbaria and some US herbaria (e.g., UC, CAS, WTU), as well as a complete review of the pertinent literature. Species not represented by a herbarium collection have been placed in an excluded list (see Appendix). Many of these were incorrectly assumed, by American authors, to range into Canada. These species were often taken up by Taylor and MacBryde (1977). We have also excluded species that are known from only a few collections taken more than 40 years ago. FORMAT The manual will be published in four parts Ð Part 1 includes Gymnosperms and Dicotyledons [Aceraceae through Cucurbitaceae]; Part 2 contains Dicotyledons [Diapensiaceae through Portulacaceae]; Part 3 includes Dicotyledons [Primulaceae through Zygophyllaceae] and Pteridophytes; and Part 4 will include the Monocotyledons. We plan to publish all four parts as a single volume. The floristic treatment is in alphabetical order by families, genera and species since most of our users may not be familiar with the more traditional ``Englerian system''. These users (e.g., foresters, wildlife specialists, park managers, amateur naturalists, students, etc.) often require specific information about a species. Thus we have attempted to included the most frequently required information. This includes the following: Synonyms: Synonyms are given only when there are references in major floristic treatments to a given species by another name or names. Common Names: A common name for each species is included. These are based mainly on names appearing most commonly in the Western North American literature. Habitat and Moisture Regime: A brief description of a species habitat preference, including moisture regime, is given. The latter uses a simple (wet - moist - mesic - dry) scale. Vegetation Zones: The elevational limits of a species are presented using vegetation zones. The zonal system used here, unlike some of the more localized zonation systems (Krajina 1965; Rowe 1959, 1972; Franklin and Dyrness 1973), has wide application in the northern hemisphere and differs only slightly from that proposed by Dansereau (1975) and Meusel et al. (1965) and recommended by LÈove (1970) in a review of the subject. The montane zone includes all continuous forests in British Columbia except for the coastal lowlands and some islands which are included in the lowland zone. The upper forests in southern British Columbia, included by some local ecologists (e.g., Krajina 1965) in the subalpine zone, is considered the upper montane zone in this work. The subalpine zone is defined as that area above the montane zone and below the upper limit of conifers as an upright tree form (Douglas 1972). In the southern part of the province, subalpine vegetation consists of a meadow/tree-clump complex (Douglas 1971, 1972), while in the northern part of the province the subalpine zone is dominated by tall shrubs (mainly three- to four-metre Salix) and scattered trees (Douglas 1974, Krajina 1975). Above the subalpine zone is the alpine zone where trees occur only in krummholz (or dwarfed) form and the vegetation is extremely short (less than one metre) and commonly referred to as alpine tundra (Krajina 1969, Douglas 1972, Douglas and Bliss 1977). The steppe vegetation zone (Daubenmire

Forest and Plant Communities of Mt Rainier • The zones show regular patterns that result in “associations” of certain shrubs and herbs relating to the dominant, climax tree species. • The nature of the understory vegetation is largely determined by the amount of moisture available and the microclimates that exist. Forest Zones of Mt Rainier • Western Hemlock Zone – below 3,000 ft • Silver Fir Zone – between 2,500 and 4,700 ft • Mountain Hemlock Zone – above 4,000 ft Since most of the field trips will start above 4,000 ft we will only discuss plants found in the Mountain Hemlock Zone and above.

  • "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.

Smith (Department of Geography) Supervisor Dr. David Atkinson (Department of Geography) Departmental Member Dr. Tobi Gardner (Victoria Capital Regional District) Outside Member ii Abstract Supervisory Committee Dr. Dan J. Smith (Department of Geography) Supervisor Dr. David Atkinson (Department of Geography) Departmental Member Dr. Tobi Gardner (Victoria Capital Regional District) Outside Member The hydrology of southwestern British Columbia is influenced by the region’s mountainous topography and climate oscillations generated from the Pacific Ocean. While much of the region is characterized as a temperate rainforest, recent summers are defined by record-breaking droughts that focus attention on the threat to regional water supply security likely to accompany future climate changes. The limited length and distribution of hydrological records in southwestern British Columbia provide poor context for resource managers tasked with developing policy and water management strategies. The purpose of the dissertation was to describe long-term variability in several key hydroclimatic variables and hydroecological interactions that may be used in updated water resource policy and management strategies.

Cliff Erosion Control with Plants CHRISTOPHER J. MARCHANT For at least half a century, perhaps several centuries, the 300 foot high sea cliffs at Point Grey have been gradually eroding. Aerial photographs indicate this, and they also show that in recent years an increasing area has been affected. It appears that there has always been a somewhat cyclical variation in the vegetation cover, which has advanced and receded coincident with fluctuation in cliff stability. However, this natural geological phenomenon has now become a major cause for concern to the University of British Columbia, since parts of the university campus sit strategically on the summit of the cliffs, and some of the land and large buildings (among them the temporary headquarters of the Botanical Garden) may be threatened with eventual subsidence into the ocean.
