Smith Open Space (70+ acres) are unique and valuable tracts of open space on the edge of Aspen – an ecological sanctuary that encompasses significant wetland and riparian ecological communities and wildlife habitat (PCOST 2015). These properties, collectively called the North Star Nature Preserve (North Star), encompass a flat bottomland bisected by the Roaring Fork River and bounded by steep mountainsides. North Star supports both xeric and mesic plant communities influenced by abiotic factors such as moisture, elevation, aspect, and geology, but also by past land management which has included grazing, farming, and irrigation. Some of the original riparian and wetland habitat on North Star was drained and willows were eliminated in order to grow agricultural grasses in the 1950’s. However, there are still areas of high-quality wetlands on North Star, including an herbaceous fen located at the northwest corner and a willow shrub wetland beaver pond complex along the southern boundary of North Star. Other vegetation types present include narrowleaf cottonwood (Populus angustifolia) riparian forest, aspen (Populus tremuloides) forests, blue spruce (Picea pungens) stands, mountain big sagebrush (Artemisia tridentata ssp. vaseyana) shrublands, and an open meadow dominated by a mosaic of agricultural upland and mesic grasslands. On the steep hillsides on the west side of the Reserve are Douglas fir (Pseudotsuga menziesii) forests and Gambel oak (Quercus gambelii) shrublands. The purpose of this study was to map and qualitatively describe the vegetation types on North Star to provide baseline information for the management of the vegetation resources. In addition, an updated vascular plant inventory was conducted. 2.0 METHODS Prior to field reconnaissance, a preliminary vegetation type map was generated based on high quality aerial imagery, existing 2-foot and 1-foot contours, existing studies, and past field reconnaissance. Field verification of the preliminary mapping was completed by Rea Orthner and Denise Wilson on August 8, September 21- 22, and October 24, 2018. During the pedestrian surveys, representative data points were taken, the names of the dominant taxa and their abundance ranking by vegetation stratum was recorded, and presence of noxious weeds was noted. Each data point was also accompanied by representative photograph(s). Based on field reconnaissance, the preliminary vegetation map was revised to incorporate the results. All vegetation mapped was also classified to the U.S. National Vegetation Classification (USNVC) standards (USNVC 2017). 3.0 RESULTS 3.1. VEGETATION CLASSIFICATION & MAPPING The U.S. National Vegetation Classification (USNVC) is a central organizing framework for documentation, inventory, monitoring, and study of vegetation in the United States from broad scale formations like forests to fine-scale plant communities. The vegetation communities at North Star were classified to the two most detailed or “lowest” levels of the classification hierarchy, alliances and associations. Alliances are classified

S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations.

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

The map was based on aerial photography from 2000 and Landsat satellite imagery from 1999 and 2001, and was designed to serve natural resources management planning activities at an operational scale of 1:24,000. There are 20 map units distributed among forest, shrubland, grassland, and wetland ecosystems. Each map unit is defined in terms of a vegetation classification that was developed for the preserve based on 348 ground plots. An annotated legend is provided with details of vegetation composition, environment, and distribution of each unit in the preserve. Map sheets at 1:32,000 scale were produced, and a stand-alone geographic information system was constructed to house the digital version of the map. In addition, all supporting field data was compiled into a relational database for use by preserve managers. Cerro La Jarra in Valle Grande of the Valles Caldera National Preserve (Photo: E.

Squilchuck State Park is a 263 acre park on the east slope of the Cascade Mountains in Central Washington, located largely in the transition zone between shrub-steppe and montane forest. Plant community polygons were delineated prior to the initiation of field surveys using or- thophotos and satellite imagery. These polygons were then ground checked during the vegetation surveys, which were conducted simultaneously with the rare plant inventories. All plant associa- tions were determined using theField Guide for Forested Plant Associations of the Wenatchee National Forest(Lilybridge et al, 1995) The Douglas-fir dominated forest above the lodge, on the eastern slopes of the park. The forest on this east slope is in places heavily overstocked and the trees supressed. Vegetation surveys and plant inventories were conducted by two field personnel (one bota- nist, one GIS technician) on June 11th, and again by 4 field workers on August 13 (two botanists and two GIS technicians).

Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.
