Current Research

My current research projects include; Effects of forest restoration treatments on northern spotted owl prey abundance in the Eastern Cascades; Effects of wildfire and forest restoration treatments on northern goshawks in the Colville National Forest; Assessing effects of climate change on wildlife and habitats in south-central Oregon; Developing and applying methods to assess regional-scale habitat connectivity patterns; Individual-based population simulation modeling to evaluate the effects of disturbance and landscape change on sensitive wildlife populations.

Past Research
Past research projects have included; Assessing the compatibility of fuel treatments, fire risk, and conservation of northern spotted owl habitats and populations in the Eastern Cascades (a multi-scale, multi-process simulation study); Interactions between northern spotted owls and barred owls in the Eastern Cascades, Washington; Barred owl space use and habitat selection in the Eastern Cascades, Washington; Movements and herbivory of elk in the Yakima Basin, Washington; Multi-objective decision making in land management using Pareto optimality (Fuelsolve); Landscape permeability for large carnivores in Washingon; Assessment of wildlife movement and habitat linkage patterns near Interstate-90 Snoqualmie Pass, Washington; Winter habitat selection and habitual movement routes of wolves in the North Fork of the Flathead River Basin, Montana and British Columbia.
Research Interest

My research focuses on understanding the relationship between animal populations, landscape patterns, landscape change, and disturbance processes. I employ field studies, spatial analysis, and simulation models to evaluate the effects of landscape change on wildlife distribution and population function.

Research Highlights

Forest Structure Characteristics Within Barred Owl Home Ranges are Similar to Areas Used by Spotted Owls

Year: 2015
Competitive interactions with barred owls are an important factor contributing to the population decline of the threatened northern spotted owl. Prior to the turn of the 20th century, barred owls were only found east of the Mississippi River. Through the first half of the 20th century barred owls ex...

Fire as a tool

Year: 2018
Landscape-scale forest restoration programs that incorporate managed wildfire and prescribed fire lead to more pronounced reductions in fire severity in frequent-fire forests.
