Monitoring Ecosystem
Health with Wildlife
My primary interest is the use of umbrella species to measure the outcomes of efforts to restore ecosystems. Specifically, my work has centered around two grouse species (lesser prairie-chicken and greater sage-grouse) that require spatio-temporal heterogeneity in vegetation communities at broad scales to satisfy their life history needs.
The work we do!
More recently, I have begun work in the wetlands of the Klamath Basin and the National Wildlife Refuge Complex therein, examining the importance of these emergent wetland systems to breeding waterbirds (e.g., yellow rail) and other ecosystem services. Additionally, my work has expanded to examine different mitigation measures for raptor collision and mortality as it relates to alternative energy production and electric transmission.
Umbrella Species
-
If the diverse needs of these species are being met through conservation and restoration then the broader suite of fauna and flora in these regions benefit. Another component of our work examines the “working lands” aspect of these landscapes, and seeks to find land-use practices (primarily agricultural) that are sustainable in the context of the system, species, and those using it. Thus, using rigorous field studies (e.g., GPS-PTT tracking technology) we measure changes in space use, resource selection, and demographic rates of birds to assess the effectiveness of various conservation actions to restore ecosystem function.
Working Lands
& Co-produced science
-
The foundation of our research is one of co-produced science that has led directly to actionable knowledge and coupling wildlife resources with human dimensions in working landscapes. Our research has always been practical and strives to be proactive in tackling imminent natural resource issues, including the effects wildfire and invasive grasses, juniper encroachment and its removal on space use and demography of wildlife in upland systems.
Creating
Understanding
-
As scientists, we often tend to fall short on conveying the story of our research outside of the peer-reviewed world. One of the greatest learning experiences for us has been developing effective outreach and education products. Converting the peer-reviewed literature to a medium that practitioners and the public can readily access is paramount to making actionable-science. Our lab has designed multi-media resources (e.g., videos, print, Instagram, etc.,) and workshops with the goal to improve general education and implementation of our applied science.
Summary
In our view, we need science to help guide future restoration efforts to the places that are likely to have the largest ecological impact. It is our goal and hope to identify those areas of highest restoration priority so that we can give these rare and amazing species the chance they deserve.
