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.

    RODEN CRATER Within a dormant volcano on the Arizona plains, a radical art experiment is being constructed.

  • Crinkle-Awn Fescue), a Region 1 Sensitive Species, on the Nez Perce and Clearwater National Forests
    FIELD INVESTIGATION OF FESTUCA SUBULIFLORA (CRINKLE-AWN FESCUE), A REGION 1 SENSITIVE SPECIES, ON THE NEZ PERCE AND CLEARWATER NATIONAL FORESTS by Christine C. Lorain Natural Heritage Section Nongame/Endangered Wildlife Program Bureau of Wildlife November 1989 Idaho Department of Fish and Game 600 South Walnut, P.O. Box 25 Boise, Idaho 83707 Jerry M. Conley, Director Cooperative Challenge Cost Share Project Nez Perce National Forest Idaho Department of Fish and Game ABSTRACT A field investigation of Festuca subuliflora (crinkle-awn fescue) was conducted on the Nez Perce National Forest by the Idaho Department of Fish and Game's Natural Heritage Program. The investigation was a cooperative Challenge Cost-share project between the Department and the Nez Perce National Forest. Crinkle-awn fescue, a Region 1 Sensitive Species, is a Pacific coastal disjunct in northern Idaho. Principal populations of this species occur west of the Cascade Mountains, mostly near the coast. The only populations east of the Cascade crest are in the moist, low-elevation canyons of the Selway and North Fork Clearwater Rivers and the Elk Creek Falls vicinity of northern Idaho. Data gathered during the 1989 field season reveals that crinkle-awn fescue is scattered within suitable habitats in the western redcedar zone. A total of 23 new populations at 21 sites are documented, with the majority of these supporting less than 100 individuals. The only previously known Idaho site was relocated and permanent monitoring plots were established at this site. All but one of the Idaho populations are located on lands administered by the Nez Perce or Clearwater National Forests.Several recommendations are made relative to the long-term viability and conservation of crinkle-awn fescue on these forest lands.

Cuarte km 1, E-22071 Huesca, Spain Institute of Desertification Research, CSIC, Valencia, Spain '^ Friedrich-Schiller University, Jena, Germany Smithsonian Institution, Washington, DC, USA Received 25 May 2007; revised 4 October 2007; accepted 26 November 2007 Available online 5 December 2007 Abstract Divergence times and biogeographical analyses liave been conducted within the Loliinae, one of the largest subtribes of temperate grasses. New sequence data from representatives of the almost unexplored New World, New Zealand, and Eastern Asian centres were added to those of the panMediterranean region and used to reconstruct the phylogeny of the group and to calculate the times of lineage- splitting using Bayesian approaches. The traditional separation between broad-leaved and fine-leaved Festuca species was still main- tained, though several new broad-leaved lineages fell within the fine-leaved clade or were placed in an unsupported intermediate position. A strong biogeographical signal was detected for several Asian-American, American, Neozeylandic, and Macaronesian clades with dif- ferent aifinities to both the broad and the fine-leaved Festuca. Bayesian estimates of divergence and dispersal-vicariance analyses indicate that the broad-leaved and fine-leaved Loliinae likely originated in the Miocene (13 My) in the panMediterranean-SW Asian region and then expanded towards C and E Asia from where they colonized the New World.
