  • Balancing Timber Production and Conservation in the Oregon Coast Range: an Examination of the Response by Birds and Bird-induced Ecosystem Services to Forest Management at Multiple Scales

    Creator:
    Harris, Scott H.
    Abstract:
    Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...

  • Snow Grain Evolution in Forested and Open Regions – Implications for Remote Sensing

    Creator:
    Weiss, Sydney G.
    Abstract:
    Snow water equivalent (SWE) is a critical measurement in hydrology and water resources management. Microwave remote sensing can estimate snow water equivalent (SWE). However, the algorithms used to estimate SWE require snow grain size information. Thus, determining snow grain size is pertinent to estimate SWE. Currently, there are several models...

    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...
