Changes in climate and land use interact to create an ecological trap in a migratory species

This project evaluated the relative contribution of climatic and land-use factors on northern pintail demographic performance across the PPR. Published in “Journal of Animal Ecology” in 2020.

Doing More with Less: Removing Trees in a Prairie System Improves Value of Grasslands for Obligate Bird Species

The authors experimentally removed shelterbelts on areas in the northern tallgrass prairie in North and South Dakota USA while conducting avian surveys to evaluate hypotheses about grassland bird response to the removal of a woodland edge. Published in “Journal of Environmental Management” in 2017.

Developing spatial models to guide conservation of grassland birds in the U.S. Northern Great Plains

The authors combined data collected in 2005–2011 from 16,250 North American Breeding Bird Survey (BBS) survey points with local and remotely sensed environmental data to model the distribution of 7 grassland bird species in the Northern Great Plains of the United States. Published in “Condor” in 2017.

Precipitation and Soil Productivity Explain Effects of Grazing on Grassland Songbirds

The authors modeled bird abundance to characterize regional response to herbaceous cover, experimentally manipulated grazing to isolate its effect, and then scaled back up to evaluate how the regional environment constrains bird response to grazing. Published in “Rangeland Ecology & Management” in 2016.

Assessment of Repeat‐Visit Surveys as a Viable Method for Estimating Brood Abundance at the 10.4‐km2 Scale

This paper examines the utility of repeat-visit brood counts from 2012 to 2013 surveys in the US Prairie Pothole Region and hierarchical N-mixture models for providing estimates of abundance at a 10.4-km2 scale. Published in “Wildlife Society Bulletin” in 2018.

Avoidance of Unconventional Oil Wells and Roads Exacerbates Habitat Loss for Grassland Birds

This paper examined grassland bird response to unconventional oil extraction sites and associated roads in North Dakota.  Published in “Biological Conservation” (2015).

Effects of Wind-Energy Facilities on Breeding Grassland Bird Distribution

This paper tested grassland bird density changes one year and 2-5 years after construction of wind-energy facilities. Published in “Conservation Biology” (2015).

Using Cropland Conversion Risk to Guide Sprague's Pipit Conservation

This paper modeled pipit distribution across its breeding range, described factors shaping distribution, and assessed vulnerability to future grassland loss. Published in “Biological Conservation” (2015).

Strategic Grassland Bird Conservation Throughout the Annual Cycle

This paper presents results of a Structured Decision Making workshop focused on linking social and economic drivers of landscape change to grassland bird outcomes. Published in “PLOS One” (2015).

Building the Foundation for International Conservation Planning for Breeding Ducks

This paper models breeding duck populations across the entire PPR (US and Canada). Published in “PLOS One” (2015).
