  • Ecology of aquatic habitats associated with stream margins

    Creator:
    Moore, Kelly M. S.
    Abstract:
    The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

  • Spatial patterns of invasion by exotic plants in a forested landscape

    Creator:
    Parendes, Laurie Anne, 1958-
    Abstract:
    Few landscapes are immune to invasion by exotic plant species. The forested landscape in the western Cascade Range of Oregon appears to have some barriers to invasion, but the extensive road network provides a corridor and habitat for a suite of exotic species to enter and become established. This study...

  • Ecology of populations of Van Dyke's salamanders in the Cascade Range of Washington State

    Creator:
    McIntyre, Aimee P.
    Abstract:
    The Van Dyke's salamander (Plethodon vandyke,) is a rare species endemic to Washington State. It has been found in cool moist microhabitats along streams, splash zones of waterfalls, and headwater seeps. We explored the association of the Van Dyke's salamander with hydrologic condition, geomorphology, disturbance characteristics, and vegetation structure in...

  • Empirical modeling of windthrow occurrence in streamside buffer strips

    Creator:
    Drake, Timothy P.
    Abstract:
    Streamside buffer strips provide numerous benefits to stream ecosystems. The buffer strips create shade, provide shelter for wildlife, act as barriers to logging debris during and after timber harvest, and serve as a continued source of large woody debris. Quantifying woody inputs resulting from windthrow provides managers with estimates for...
