  • Choosing efficient land allocations and forest management regimes for biodiversity

    Creator:
    Shunk, Neal J.
    Abstract:
    Increasing rates of species imperilment and the loss of biological diversity in naturally functioning ecosystems can be directly linked to accelerated urban development and the conversion of natural habitats to satisfy the needs of man. In combating this loss of biodiversity, scientists and policy makers alike recognize the relevance of...

  • Quaking aspen persistence in three Oregon landscapes

    Creator:
    Seager, S. Trent
    Abstract:
    Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...

  • Drivers of plant community dynamics in sagebrush steppe ecosystems : cattle grazing, heat and water stress

    Creator:
    Reisner, Michael D.
    Abstract:
    Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...

  • Persistence of western juniper resource islands following canopy removal

    Creator:
    Miwa, Christopher
    Abstract:
    Western juniper (Juniperus occidentalis) cover has more than doubled within the last century and currently occupies over 9 million acres in the Intermountain West. Encroachment has altered the spatial distribution of soil nutrients and plants in these systems, forming nutrient enriched 'resource islands,' under tree canopies. The purpose of this...

  • Multi-scale relationships between aspen and birds in the northern Yellowstone ecosystem

    Creator:
    Hollenbeck, Jeff P., 1967-
    Abstract:
    I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by...

  • Optimizing spatial and temporal aspects of nature reserve design under economic and ecological objectives

    Creator:
    Nalle, Darek J.
    Abstract:
    Alteration of natural areas in attempts to support increasing human populations has been a crucial yet less publicized contributor to the fall of many of the world's greatest civilizations, since healthy ecosystems can help maintain stable societies and economies. Given this unhappy fact and the ancient relationship between people and...

  • Land ownership and forest cover in the Oregon Coast Range : spatial pattern and social ground-truthing

    Creator:
    Stanfield, Brooks J.
    Abstract:
    We use qualitative and quantitative methods to explore social and spatial relationships between land ownership and forest cover in the Oregon Coast Range. Using a Geographic Information System (GIS) and regression analysis, we tested for spatial relationships between the structure of land ownership and forest cover across 66 watersheds in...

  • Conifer regeneration, understory vegetation and artificially topped conifer responses to alternative silvicultural treatments

    Creator:
    Huff, Tristan
    Abstract:
    Historically, between 40-60% of the Coast Range of Oregon was comprised of structurally diverse, old forests initiated by disturbances of various spatial scales ranging from thousands of acres (large fires) to the size of a single tree (windthrow). The predominant regeneration method of the past several decades, however, has been...

  • Trophic cascades and large mammals in the Yellowstone ecosystem

    Creator:
    Painter, Luke E.
    Abstract:
    Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...
