I am a Research Wildlife Biologist at the U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center. My research focuses on providing information to support management and conservation of native wildlife species and their habitats.
My research interests include forest and wildlife ecology, conservation of biodiversity in managed forests, conservation and management of native Willamette Valley ecosystems, and riparian songbird response to floodplain restoration. Much of my work has focused on the biologically and economically important conifer forests of the PNW that are intensively managed for multiple uses and represent a large area in public domain. My research projects are designed to increase understanding of how conifer forest management affects biodiversity across a range of spatial and temporal scales, and to provide science-based information that can be directly applied in an adaptive management framework.

Birds as Indicators of Ecosystem Health
Birds are excellent indicators of ecosystem condition because they are responsive to environmental change, have important ecological functions – such as seed dispersal and insect consumption, and are easy to observe.Habitat Mapping and Modeling
Accurately quantifying and mapping wildlife habitat is critical to investigations of species distribution and habitat relationships, and can greatly facilitate management of forests for multiple resources. However acquiring field-based, empirical data is often costly and labor intensive. Modeling provides an alternative technique for describing and mapping habitat, but the usefulness of models...Effects of Management on Wildlife and Habitats
Conifer forests in the Pacific Northwest are biologically and economically important, are intensively managed for multiple uses, and represent a large area in public domain. Therefore, understanding how management of conifer forests affects biodiversity across a range of spatial and temporal scales is critical for land management agencies.Ecology of Rare and Declining Species and Communities of Conservation Concern
Special status species and habitats are often sentinels of accelerated ecosystem change and, by definition, are priorities for protection, restoration, or focused management.Disentangling the Effects of Climate and Landscape Change on Bird Population Trends in the Western U.S. and Canada
Climate change has been implicated in the range shifts and population declines of many species, but the confounding of climate change with other variables, particularly landscape change, hampers inference about causation. Climate envelope models have been used to predict population trends and future distributions, but the reliability of such predictions remains relatively unknown; without tests of - Data
