Current Research

I am currently focused on developing tools that quantify habitat for forest vertebrates listed as threatened, endangered or of special concern by state and /or federal management agencies. I am also working on trend models that can show resource managers which structural characteristics a species' habitat is limiting or is changing in abundance over time.

Species currently focused on include the pinyon jay, Mexican spotted owl, and red squirrel. Ecosystems currently focued on include pinyon-juniper woodlands and their ecotones with sagebrush steppe, mixed-conifer stands, and lodgepole pine stands that have whitebark pine as a component.

Research Interests

My interests include creating economically friendly modeling tools that resource managers can access at any time to assess the state of a species' habitat at large scales (landscape, state, ecoregions). I am also interested in tracking changes in forest structure over time as it relates vertebrate species habitat.

Past Research

Effect of isolation on small mammals in a sage-steppe matrix, Quantification of nesting habitat for Lewis' woodpecker in Utah, Assessment of seasonal habitat for mule deer in pinyon-juniper woodlands containing sagebrush, Predicting occurrence of heartrot fungus in aspen and its implications to cavity-nesting birds, pinyon jay habitat in pinyon-juniper woodlands.

Why This Research is Important

This research provides cost-effective habitat assessment and monitoring tools that are accessible to anyone. By using publically available Forest Inventory and Analysis data and leveraging it against state and local species occurrence information, I provide habitat estimation and trend analysis tools that can be used repeatedly over time with little cost or no financial burden to the user. This has fostered partnerships between federal, state, and local governments as well as academic institutions and non-government organizations that provide species information and input on model validity and utility.

    Pinyon jays perched atop berry-laden juniper tree.
    Over the past century, many pinyon-juniper woodlands in the Great Basin have expanded their range and increased their stand densities. These changes in structure and extent have effects on both the species that use the woodlands and to species whose habitat is being encroached by them. We observed and described where pinyon jays prefer to cache seeds in order to gain an understanding on how and where expansion and infill is likely to occur and to what extent jays are facilitating these processes.
