Current Research

1. Determine the distribution and density of breeding territories, reproduction, survival, mate and territory fidelity, recruitment, and emigration/immigration of northern goshawks on the Kaibab Plateau, Arizona. 2. Assess the relationship between goshawk demographic performance and habitat conditions on territories. 3. Identify the compositional and sturctural habitat elements that confer quality to goshawk breeding habitats. 4. Investigate post-fledgling movements and dispersal of juvenile goshawks.5. Determine the causes and consequences of dispersal of adult, breeding goshawks. 6. Identify factors affecting goshawk prey populations and the extent to which prey affects goshawk demographics. 7. Investigate the utility of genetic fingerprinting for identifying individual goshawks from in capture-recapture studies.8. Investigate the utility of using color, pattern, and shape of molted feathers for for identifying individual goshawks in mark-recapture studies. 9. Determine the effects of high vs low intensity fire on the habitat on goshawk prey populations and on goshawk habitat use.

Research Interests

My research focuses on the relationship between species' demographies -- their reproduction, survival, mate and territory fidelity -- and their habitat in order to identify habitat elements that distinguish among high quality and low quality habitats. This research necessarily requires long-term capture-mark-recapture work so that the demographic performance of known individuals can be related to the compositions and structures of habitats they use throughout their lives. Products of the research enhance our understanding of the importance of habitat characteristics in species' viability and helps managers provide quality habitats through management activities.

Past Research

An example of this demographically-based habitat research is our work on the northern goshawk, a 'sensitive' species and a candidate for listing under the Endangered Species Act. The focus of concern for this species was loss of habitat due to a forest management practices. The importance of our research on the hawk and its habitat was highlighted in a collaborative effort between animal ecologists, silviculturalists, and foresters to synthesize habitat-related knowledge of the plants and animals in this predator's food web to develop best-science management recommendations. This collaboration identified unique sets of desired habitat conditions that combined both a fine and coarse filter approach to multi-species conservation. The management recommendations were incorporated into forest plans of all National Forests in the Southwestern Region in 1996. Implementation improves visual quality, forage, wood products, and hydrologic function of forests; reduces fire hazards; and increases resilience to insects, disease, and climate change.

Why This Research is Important

1. Initiated, conducted, and continue to collaborate on a 31-year capture-recapture investigation of the relationship between the habitat composition and structure and the demography of the flammulated owl in Colorado ponderosa pine forests.2. Initiated and conducted a 10-year study of the distribution, density, territory occupancy, and reproduction of Mexican spotted owls in Colorado.3. Initiated and conducted a 4-year study of birds , mammals, and herps in aspen and spruce-fir forests in Colorado and Wyoming. 4. Collobratively initiated and conducted a northern goshawk habitat assessment for the entire Black Hills National Forest.
