A CHECKLIST OF THE VASCULAR PLANTS OF THE REDWOOD NATIONAL & STATE PARKS James P. Smith, Jr. Professor Emeritus of Botany Department of Biological Sciences Humboldt State Univerity Arcata, California 14 September 2018 The Redwood National and State Parks are located in Del Norte and Humboldt counties in coastal northwestern California. The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks. -

Abstract This work aims to assess geothermal power potential in identified high enthalpy geothermal areas in the Chilean Andes, based on reservoir temperature and volume. In addition, we present a set of highly favorable geothermal areas, but without enough data in order to quantify the resource. Information regarding geothermal systems was gathered and ranked to assess Indicated or Inferred resources, depending on the degree of confidence that a resource may exist as indicated by the geoscientific information available to review. Resources were estimated through the USGS Heat in Place method. A Monte Carlo approach is used to quantify variability in boundary conditions. -

The dataset shows con- straints on the nature of slab-derived component to mantle source. Analyzed samples show large negative Nb and Ta anomalies, and enrichment of alkaline earth elements and Pb, which are features of typical island arc volcanic rocks. Boron contents of SVZ volcanic rocks range 2.3–125.5 ppm, exhibiting marked enrichment relative to N-MORB and OIB. Both the boron contents and B/Nb ratios of the volcanic rocks increase from the southern SVZ (SSVZ) to central SVZ (CSVZ). Fluid mobile/immobile element ratios (B/Nb, Ba/Nb, Pb/Nb, and K/Nb) are used to examine slab-derived com- ponent to mantle source. -

Dynamical Regime and Advance Rate of Lava Flows Using Its Deposit Characteristics: 2 Cases from the Lonquimay and Villarrica
IAVCEI 2013 Scientific Assembly - July 20 - 24, Kagoshima, Japan Forecasting Volcanic Activity - Reading and translating the messages of nature for society 0P2_3H-O11 Room A5 Date/Time: July 20 17:15-17:30 Dynamical regime and advance rate of lava flows using its deposit characteristics: 2 cases from the Lonquimay and Villarrica volcanoes, Southern Andes of Chile Maria Angelica Contreras1,2, Angelo Castruccio1,2 1Universidad de Chile, Chile, 2Centro de Excelencia en Geotermia de los Andes (CEGA), Chile E-mail: [email protected] The advance of lava flows is controlled by the effusion rate, rheology, topography and cooling effects. Consequently, the deposits of lava flows would reflect the interplay between these factors. We tested a methodology to estimate the variations of flow rate and velocity of ancient lava flows using its deposit dimensions, textural characteristics and petrography. We studied the deposits of two lava flows with contrasting styles generated during historical times in the Southern Andes of Chile: the 1971 eruption of Villarrica volcano and the 1988-89 eruption of Lonquimay volcano. Both eruptions have a record of its duration and advance rate, so we can test different dynamical models in order to fit better the available data. The Villarrica eruption lasted a couple of days and the resulting lava flow reached a length of 16.5 km, with thicknesses of 3-15 m, depending mainly on the channelling of the flow. The morphology is transitional between Pahoe-hoe and Aa. Clasts morphologies are mainly rubbly and slabby, ranging from a few cm to a couple of meters in diameter. -

Evolution of Grasses and Grasslands in South America
TAXON 24(I): 53-66. FEBRUARY 1975 EVOLUTION OF GRASSESAND GRASSLANDS IN SOUTH AMERICA Arturo Burkart* Summary This is a discussion of the South American grasslands from the standpoint of their evolution and composition. The tribes are considered in relation to climate, and grasses are classified as mega-, meso-, or microthermic with respect to their temperature requirements. The principal grassland regions are three: (A) Tropical and Subtropical, which include the Llanos of the Orinoco River system and the Campos Cerrados of Central Brazil; (B) Temperate, including the Pampa of Argentina and the Campos of Uruguay; and (C) Cold Country Grasslands, which are the Steppes of the high Andes and Patagonia, and also the Pairamos of Colombia and Ecuador. Some attention is given to the floristic composition of each of these regions. The subject of endemism is dealt with, as well as the problem of disjunct distribution. Included is a discussion of changes brought about by agriculture and ranching in historic times, and what may be expected in the future. INTRODUCTION The Gramineae, with about 6oo genera and some 6ooo species, is one of the largest families of flowering plants. It is a truly cosmopolitan group, and remarkable because of the capacity of its members to form the domi- nant vegetation over large areas of the earth's surface. The terms steppes, savannas, prairies, pusztas, campos or pampas all refer to vegetation types in which grasses are dominant. To quote Ronald Good (1953; p. 53) "Pride of place must certainly go to the Gramineae . ., the great family ... Not only do the grasses reach to the furthest land in the north and to the borders of Antarctica in the south, but their degree of distribution is usually particularly complete and continuous. -

The ranks are scaled from 0 to 100, with 0 representing a plant that poses no threat to native ecosystems and 100 representing a plant that poses a major threat to native ecosystems. Description Slender hairgrass is a tufted, biennial to short-lived perennial grass that grows 25 to 80 cm tall from fibrous roots. Stems are numerous, slender, and slightly rough. Leaves are mostly basal. Basal leaves are threadlike, 2 to 30 cm long and rarely more than 1.5 mm wide. Stem leaves are flat or rolled inwards and 1 to 1.5 mm wide. Ligules are entire but usually split, short-hairy, pointed, and 2.5 to 9 mm long. Panicles are narrow, pale green to purple-tinted, erect or nodding, 5 to 30 cm long, and 5 to 15 mm wide with erect to ascending branches. Spikelets are narrowly v-shaped and 3 to 6.7 mm long. Glumes are three-nerved, equaling or exceeding the florets, narrowly lanceolate, and 3.1 to 5.5 mm long. Lemmas are 1.7 to 4.3 mm long with 1.5 to 5.5 mm long awns. -
Southern Andes Supersite Coupled Geohazards at Southern Andes: Copahue-Lanín Arc Volcanoes and Adjacent Crustal Faults
Version 1.3 15 October 2018 www.geo-gsnl.org Biennial report for Permanent Supersite/Natural Laboratory GeoHazSA: Southern Andes Supersite Coupled geohazards at Southern Andes: Copahue-Lanín arc volcanoes and adjacent crustal faults History https://geo-gsnl.org/supersites/permanent- supersites/southern-andes-supersite/ Supersite Coordinator Luis E. Lara, SERNAGEOMIN, CIGIDEN, Av. Santa María 0104, Santiago, CHILE 1 Version 1.3 15 October 2018 www.geo-gsnl.org 1. Abstract The Southern Andes (33°-46°S) is a young and active mountain belt where volcanism and tectonic processes pose a significant threat to the communities nearby. In fact, only recent eruptions caused evacuations of 250-3500 people and critical infrastructure is present there. The segment here considered corresponds to a low altitude orogen (<2000 masl on average) but characterized by a high uplift rate as a result of competing tectonic and climate forces. This Supersite focuses on a ca. 200 km long segment of the Southern Andes where 9 active stratovolcanoes (Copahue, Callaqui, Tolhuaca, Lonquimay, Llaima, Sollipulli, Villarrica, Quetrupillan and Lanín) and 2 distributed volcanic fields (Caburgua and Huelemolles) are located, just along a tectonic corridor defined by the northern segment of the Liquiñe-Ofqui Fault System (LOFS). Activity of the LOFS has been detected prior to some eruptions and coeval with some others. There are several tectonic and volcanic models to be investigated that derive from a strong two-way coupling between tectonics and volcanism, recently detected by either geophysical techniques or numerical modeling. Hazards in the segment derive mostly from the activity of some of the most active volcanoes in South America (e.g., Villarrica, Llaima), others with long-lasting but weak current activity (e.g., Copahue) or some volcanoes with low eruptive frequency but high magnitude eruptions in the geological record (e.g., Lonquimay).
