  • The effect of burrowing mammals on the hydrology of a drained riparian ecosystem

    Creator:
    Cassidy, James Richard
    Abstract:
    Many species of rodents and insectivores live in subterranean burrows in soils throughout the world. The soil surface perforations of burrow entrances are often connected to complex, subsurface tunnel networks. Burrow entrances and associated subsurface tunnel networks represent a link between surface and subsurface ecological function. Anecdotal observations of surface-water...

  • Physical characteristics of forest soils after timber harvest and tillage in central Oregon: a case study

    Creator:
    Litton, Sabrina
    Abstract:
    This study examined the effects of timber harvest and subsoiling on soil physical properties considered important to forest productivity and hydrologic concerns. Ground based mechanical timber harvesting on some soil types can cause soil disturbance including compaction. These effects in turn can influence multiple important soil physical properties that affect...

  • Road surface runoff for the Oak Creek watershed: the influence of hillslope and road characteristics

    Creator:
    Ellingson, Kami S.
    Abstract:
    Understanding how forest roads interact with hillslope hydrology by intercepting and/or rerouting storm runoff will better enable land managers to reduce erosion related to forest roads. Watershed scale knowledge of how culvert runoff response varies across the landscape would provide valuable information to those individuals designing and maintaining forest road...
