Fraga ABSTRACT: We present an annotated catalogue of the vascular flora of the upper Santa Ana River watershed, in the southern San Bernardino Mountains, in southern California. The catalogue is based on a floristic study, undertaken from 2008 to 2010. Approximately 65 team days were spent in the field and over 5,000 collections were made over the course of the study. The study area is ca. 155 km2 in area (40,000 ac) and ranges in elevation from 1402 m to 3033 m. The study area is botanically diverse with more than 750 taxa documented, including 56 taxa of conservation concern and 81 non-native taxa. Vegetation and habitat types in the area include chaparral, evergreen oak forest and woodland, riparian forest, coniferous forest, montane meadow, and pebble plain habitats.

  • Diversidad De Plantas Y Vegetación Del Páramo Andino
    Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1).

  • Distribution of the Native Grasses of California
    HILGARDIA A Journal of Agricultural Science Published by the California Agricultural Experiment Station VOLUME 17 APRIL, 1947 NUMBER 9 CONTENTS DISTRIBUTION OF THE NATIVE GRASSES OF CALIFORNIA ALAN A. BEETLE UNIVERSITY OF CALIFORNIA • BERKELEY, CALIFORNIA HILGARDIA A Journal of Agricultural Science Published by the California Agricultural Experiment Station VOL. 17 APRIL, 1947 NO. 9 DISTRIBUTION OF THE NATIVE GRASSES OF CALIFORNIA1 ALAN A. BEETLE2 THE grasses, supplemented by certain legumes, form the principal basis for range wealth. The natural forage value of the Gramineae as a whole makes an intensive study of their characteristics important, for the broader the knowledge concerning them the more readily may any problem be met. The following paper presents a picture of the current distributions of grasses in California, together with evidences of their floral origins by migration from other regions. Vegetation has many characteristics which are not always apparent at first glance. For instance, certain elements of the vegetation are native in their location, some are native elsewhere and have only recently been introduced. Some are old species often representative of a primitive condition in their genus, still others appear to be recently evolved. Some of the migrants arrived in California from the north during glacial periods, some crossed the ocean, and others came from the south during interglacial periods. Some plants are distributionally restricted for a number of reasons, including: (1) specialization as to habitat or environmental repression, as the species of vernal pools; (2) recent origin (plants sometimes referred to as neoendemics or initiates), as the endemic varieties of Distichlis spicata; (3) ancient origin (paleoendemics or relics); and (4) genotypic specialization (genetic endemics).

  • Grasses-Accts 1
    AGROPYRON Wheatgrass The name Agropyron comes from the Greek word for wild wheat, and Agropyron species have a wheat-like appearance. There has been some con- troversy concerning the species included in this genus. Hitchcock et al. (1969) recognized nine species of Agropyron. Today there is general agree- ment that Agropyron should be restricted to the “crested wheatgrasses.” These species are perennial plants with a stem axis that does not come apart at maturity, a flowerhead that is a spike, spikelets that diverge from the stem axis at an angle of 30° or more, and one spikelet at each node. The species that were traditionally contained within Agropyron are now treated in Elymus, Thinopyrum, Pascopyrum, and Pseudoroegneria. There are three British Columbia species remaining in the genus Agropyron, and these are Crested Wheatgrass, Desert Wheatgrass, and Siberian Wheatgrass. In the Columbia Basin region, only Crested Wheatgrass and Siberian Wheatgrass have been collected. Agropyron—Adapted from Douglas et al. (1994) 1a. Spikelet spread from the stem axis 30° or more; the distance between the spikelets is less than 1 mm . Agropyron cristatum 1b. Spikelet pressed to the stem axis; the distance between the spikelets is greater than 1 mm . Agropyron fragile Agropyron cristatum (L.) Gaertn. ssp. pectinatum (Bieb.) Tzvelev Crested Wheatgrass Plant: Agropyron cristatum is an introduced species that grows 50–100 cm tall. It is a tufted perennial with densely fibrous roots, but no rhizome. The flowerhead is composed of a flattened spike containing spikelets that resem- ble the teeth in a comb—thus the subspecies name pectinatum is from pectinate, meaning comb-like.

RMRS-RP-1. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky.Mountain Research Station. 36 p. Vegetation at the Glacier Lakes Ecosystem Experiment Site, a 600 ha research site at 3200 to 3500 m elevation in the Snowy Range of southeastern Wyoming, was categorized and described from an intensive sampling of species abundances. A total of 304 vascular plant taxa were identified through collection and herbarium documentation. Plots with tree species were separated from those without tree species for ordination and classification analyses. Detrended correspondence analysis was used to order plots along major axes of composition variation, which are inferred moisture and topographic gradients. Cluster analysis was used to categorize plots based on composition similarity. The resulting groups were named according to species dominants. We identified and described in detail 4 meadow, 4 thicket or scrub, 3 krummholz, and 2 forest plant associations. Key words: alpine vegetation, subalpine vegetation, plant associations, cluster analysis, floristics, Wyoming, Snowy Range, Medicine Bow Mountains The Authors Claudia M.
