I am a Scientist Emeritus at the USGS Forest and Rangeland Ecosystem Science Center. My research focuses on wildlife ecology, monitoring, and management.
I study mammalian ecology and wildlife-habitat relationships. My personal interests include outdoor activities, my family, reading biographies and history, and traveling.

Fisher Restoration on the Olympic Peninsula
Researchers at the Forest and Rangeland Ecosystem Science Center, Olympic Field Station, have been involved in fisher restoration to Washington’s Olympic Peninsula since 2008, when fishers were reintroduced to the peninsula following decades of extirpation.
Elwha River ScienceScape: Understanding Ecosystem Recovery Following Large-Scale Dam Removal
The Elwha River – located on the Olympic Peninsula in Washington - is home to an iconic dam removal and ecosystem restoration project. The Elwha offers a unique setting to explore the ecosystem level effects of dam removal and river restoration because of its prominence, such as large sediment volume, several salmon populations, and pristine wilderness.
USGS science supporting the Elwha River Restoration Project
The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington.
Wildlife Monitoring in National Parks
Maintaining a current understanding of ecological conditions is fundamental to the National Park Service in meeting its mission to preserve park resources in an unimpaired state for future generations. Ecological monitoring establishes reference conditions, which over time help to define the normal limits of natural variation, determine standards for comparing future changes, and identify the need...
Mammalian Ecology and Management in Protected Areas
National parks and other protected areas are key components of the wildlife conservation landscape. The goal of wildlife managers in national parks is to preserve the ecological integrity and authenticity of natural systems for future generations. Wildlife populations of national parks, however, are in continuous flux as a result of changing land uses outside their boundaries, climate variability...
