Yukon Conservation Data Centre Vascular plant watch list Updated February 2019 This is a list of vascular plants for which more information is needed before a conservation status can be determined, but which may be threatened or endangered in Yukon or throughout their range. The Yukon Conservation Data Centre is not mapping these species in our database at this time, but is actively seeking reports on known populations so that in future we may be able to make an informed assessment of their conservation status. Some species on this list may be eventually placed on the Track List, while others will be removed from the list as more populations are reported. We encourage all to report sightings of these species to us but do not require detailed information. A simple location and date with your contact information will suffice. Documentation, such as a specimen or a photograph, is required to confirm identification.

Hamzeh Received 2015. 02. 20; accepted for publication 2015. 05. 12 ee, B. & Assadi, M. 2015. 06. 30: Taxonomical notes on the genus Piptatherum P. Beauv. (Poaceae) in׳Hamzeh Iran. –Iran. J. Bot. 21 (1): 01-09. Tehran. Piptatherum denaense is described as a new species from south west of Iran, Dena Mountain. It is close to P. laterale but differs from it by having glabrous lemma in lower half and toward the apex, narrower vegetative shoots and unbearded anthers. Piptatherum holciforme subsp. holciforme var. glabrum is not accepted as a distinct variety. Piptatherum sphacelatum formerly known as a synonym of P. molinioides is established as a separate species due to having distinct morphological characters as well as molecular differences based on literature. Thus, the number of taxa in the genus Piptatherum changes to 9 species, 2 subspecies and 4 varieties in Iran. An identification key to Piptatherum taxa occuring in Iran is provided. The distribution map of P. denaense with P. laterale subsp. laterale and the illustration of the new species are included. ee (correspondence <[email protected]>) & Mostafa Assadi, Research Institute of Forests and׳Behnam Hamzeh Rangelands, P.

CONTRIBUTIONS FROM THE United States National Herbarium Volume XII, Part 3 TXE&3 OF AMERICAN GRASSES . / A STUDY OF THE AMERICAN SPECIES OF GRASSES DESCRIBED BY LINNAEUS, GRONOVIUS, SLOANE, SWARTZ, AND MICHAUX By A. 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.

    Natural Resources Conservation Service Ecological site R051XY286CO Rocky Foothills Last updated: 7/19/2021 Accessed: 09/25/2021 General information Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site. MLRA notes Major Land Resource Area (MLRA): 051X–High Intermountain Valleys This MLRA encompasses the San Luis Valley in south central Colorado and the Taos Plateau and Taos alluvial fans of north central New Mexico. As part of the northern portion of the Rio Grande Rift, the MLRA consists of large, alluvium filled basins washed down from adjacent mountain ranges. The Rio Grande River flows through this MLRA, continuing its long function of carrying mountain sediment down to the basin. Cenozoic volcanism is an extensive characteristic of the MLRA where large basalt flows with volcanic hills and domes are abundant.Ancient Lake Alamosa is a large feature within the MLRA.

    Atlas of Rare Endemic Vascular Plants of the Arctic Technical Report No. 3 About CAFF Theprogram for the Conservation of Arctic Flora and Fauna (CAFF) of the Arctic Council was established lo address the special needs of Arctic ecosystems, species and thcir habitats in the rapid ly developing Arctic region. Itwas initiated as one of'four programs of the Arctic Environmental Protcction Strategy (AEPS) which was adopted by Canada, Denmark/Greenland, Finland, lceland, Norway, Russia, Swcdcn and the United States through a Ministeria! Declaration at Rovaniemi, Finland in 1991. Other programs initi­ ated under the AEPS and overlaken hy the Are.tie Council are the ArcticMonitoring and assessment Programme (AMAP), the program for Emergency Prevention, Preparcd­ ness and Response (EPPR) and the program for Protection of the Arctic Marine Envi­ ronment (PAME). Sinceits inaugural mccti.ng in Ottawa, Canada in 1992, the CAFF program has provided scientists, conscrvation managers and groups, and indigenous people of the north with a distinct forum in which lo tackle a wide range of Arctic conservation issues at the cir­ cumpolar level. CAFF's main goals, which are achieved in keeping with the concepts of sustainable developrnertt and utilisation, are: • to conserve Arctic Jlora and fauna, thcir diversity and thcir habitats; • to protect the Arctic ecosystems from threats; • to improve conservation management laws, reg ulations and practices for the Arclic; • to integrale Arctic interests into global conservation fora. CAFF operates rhrough a system of Designated Agencies and National Representatives responsible for CAFF in thcir rcspcctivc countries. CAFF also has an International Work­ ing Group wh.ith has met annually to assess progrcss and to develop Annual WorkPlans.

    Restoration of Ingrown Dry Forests Forest Science Program 2004/05 Annual Technical Report Understory Succession following Ecosystem Restoration of Ingrown Dry Forests FSP Project Number: Y051069 Reg Newman, John Parminter and Sheryl Wurtz April 2005 Restoration of Ingrown Dry Forests Abstract Restoration of ingrown stands of ponderosa pine (Pinus ponderosa) and interior Douglas-fir (Pseudotsuga menziesii var. glauca) was carried out using a prescription of partial cutting and slashing in 1999 and 2000. Partial cutting consisted of thinning the forest canopy and removing intermediate layer trees. Slashing consisted of cutting pre-commercial, intermediate layers to reduce the risk of crown fire during prescribed understory burns. The ponderosa pine stand was subjected to a prescribed fire in April 2004. The partial-cut treatment opened the canopy by 30% at the ponderosa pine site. Three years later, pinegrass production had recovered at a greater rate than most bunchgrasses. Bunchgrass composition had declined in the plant community relative to pinegrass (Calamagrostis rubescens). Total forage standing crop had not yet increased beyond pre-treatment levels. The partial-cut treatment opened the canopy by 27% at the interior Douglas-fir site. Five years later, pinegrass production doubled while bunchgrass remained unchanged. Total forage standing crop increased by about 40%, almost all due to pinegrass increase. A key objective of dry-forest restoration is to increase the abundance of important forage species such as bluebunch wheatgrass (Pseudoroegneria spicata) and rough fescue (Festuca campestris), while reducing the abundance of their primary competitor, pinegrass. It is clear that this objective has not yet been achieved at these two sites.
