Current Research

  • Effects of wildfire and prescribed fire on populations and habitats of birds in ponderosa pine forests of the Interior West.
  • Foraging habitat ecology of black-backed woodpeckers in burned forests of southwestern Idaho.
  • Effects of bark beetle colonization and management treatments on populations and habitats of birds in ponderosa pine forests of central Montana.
  • Development of monitoring protocols for management indicator and sensitive species of woodpeckers.
  • Validation of models used to predict cavity nest occurrence of white-headed and black-backed woodpeckers.
  • Influence of postfire salvage logging on nest survival of black-backed woodpeckers in south-central Oregon.
  • Research Interests

    Functioning in a Science Support position, my research interests largely reflect those of the Wildlife and Terrestrial Ecosystems Program and my supervisor - Vicki Saab. As such, we launched into studying fire and avian ecology in 1994. Since that time, we have contributed to understanding long-term effects of management activities on populations and habitats of birds, with an emphasis on cavity-nesting species. Today, our interests still focus on songbirds and cavity nesters in general, in areas such as modelling breeding habitats and nest survival, but also on individual species that present unique challenges to such land management activities as fuels reduction, beetle suppression, and pine forest restoration, and on predictions of population responses under changing climate scenarios.

    Past Research

    Our research helps support conservation and persistence of bird populations and their habitats under various disturbance regimes and spatial scales. Our outputs tend to be recommendations or tools designed to facilitate land management decisions and build on current scientific knowledge.

    Why This Research is Important

  • Calculated the home range size of black-backed woodpeckers in burned forests of southwestern Idaho.
  • Estimated the detection probabilities of hairy and black-backed woodpecker nests in south-central Oregon.
  • Analyzed longevity of snags in relation to wildfire and postfire salvage.
  • Determined factors that influence occupancy of nest cavities in recently burned forests.
  • Developed a field protocol to survey and monitor cavity-nesting birds.
  • Studied the responses of cavity-nesting birds to wildfire and salvage logging in mixed conifer forests of southwestern Idaho.
  • Evaluated the response of depleted sagebrush steppe riparian system to grazing control and woody plantings.
