Wildlife Science Undergraduate program advisor
I serve as an advisor for undergraduate students in the Environmental Science and Resource Management (wildlife pathway) program. I help them with course selection and career advice.

College of Forest Resources
I am an active participant in several College and academic division-level committees. Some of these deal with governance while others deal with academic matters.

Wildlife Society Student Chapter
I serve as the faculty advisor to the Student Chapter of The Wildlife Society (TWS), a professional society of wildlife biologists and managers. TWS holds a meeting twice a month when students get together to discuss academic matters, technical aspects of wildlife biology, plan activities, and listen to invited speakers. TWS often has field trips to wildlife areas and also assists graduate students in their research.

Wildlife Science Program Coordinator
I am the over-all Coordinator for both the undergraduate and graduate programs and faculty in Wildlife Science. One of the primary responsibilities of this position is to represent these groups in various College or Universtiy committees and meetings.

Chair, Ecosystem Science Division

From January 2001 to January 2004, I served as Chair of one of the two College's academic divisions. The division has 14 tenure-track faculty and 14 research faculty. There is a wide range of academic disciplines represented in the division.

The good old days in western Montana.

I am interested in many areas of avian ecology and conservation. These include:

However, the majority of my research has been in two areas: (1)seabird ecology and conservation and (2)the basic ecology of forest birds and their response to forest management. We now have a good understanding of the basic nature of bird communities in most natural and managed coniferous forest landscapes but we need to better understand some individual species responses to environmental gradients and to forest management. Future research will be directed in these areas.


Responses of Forest Wildlife to Modified Habitats


Nearly all the funding we generate in the Wildlife Science Group is directed toward providing support for graduate students. Consequently, much of my own research is essentially cooperative efforts with graduate students. For many years I was active in seabird research in California, Washington and Alaska. In recent years, I have concentrated on forest bird ecology. I am in the process of preparing manuscripts from the results of two long-term research projects. One concerns bird communities in intensively-managed Douglas-fir forests and the other is on oak woodlands in south-central Washington. I am also concluding an extensive assessment of the common murre which includes a review of its natural history, trends in populations, threats to populations and conservation strategies. This is a study funded by the U.S. Fish and Wildlife Service and involves several other professionals as co-authors.

Since 1972, I have obtained $1,494,183 in research funding. The specific sources include the following:

My personal research currently deals with a continuation of studies of birds in oak woodlands, evaluating the effects of new silvicultural treatments on birds (U.S. Forest Service DEMO project) and the restoration of sage grouse to areas of eastern Washington where it has been extirpated. I have obtained funding for a study on winter birds of intensively-managed Douglas-fir forests.

[Trees Image] I am currently involved in two major projects. The first one is a U.S. Forest Service funded study called "Demonstration of Ecosystem Management Options"(DEMO). This study is an experimental one which attempts to assess the response of vertebrates and plants to different levels of canopy removal. We have completed two years of pre-harvest bird sampling on 24 sites using a combination of point counts and spot-mapping. We will now begin the post-harvest sampling phase. We have just completed a study of the response of birds to variable-density thinning at Ft. Lewis, Washington.
