My current research involves assessing and modeling the effects of future climate change and stressors on at-risk species and ecosystems of arctic and subarctic environments. I also am developing structured decision-aiding models and methods for informing listing decisions and threats evaluations of at-risk species and injurious invasive species; analyzing bioacoustic and soundscape attributes of landscapes under stress of fire and climate change; assessing causes and effects of sea level rise on coastal marshes; developing tools for evaluating viability of species of conservation concern under planning guidelines; and working with a wide variety of international colleagues and institutions on developing and testing risk analysis tools for biocontrol and biosecurity programs and other topics.
My past studies have included field research of bird communities in young and mature Douglas-fir forests of Klamath Mountains, California; field research on lichens, mosses, vascular plants, and invertebrates of old-forest remnants, forest plantations, grazed and ungrazed riparian areas, and recent forest fires in the southern Washington Cascades and eastern Oregon (the Old Forest Remnants Study); analysis of vocalizations of the African Wood Owl throughout Africa (potentially identifying at least a new subspecies of owl); and developing new analysis methods for determining age class of martens from non-invasive samples.
