Kate Schoenecker, PhD
Kate Schoenecker is a Supervisory Research Wildlife Biologist at the Fort Collins Science Center.
Dr. Kate Schoenecker has been studying the ecology of ungulates for 26 years as a Research Wildlife Biologist at the U.S. Geological Survey (USGS) Fort Collins Science Center, Colorado. She received a Master’s degree from the University of Arizona, Tucson studying desert bighorn sheep and a PhD from Colorado State University on bison and elk grazing ecology in the Great Sand Dunes National Park & Baca National Wildlife Refuge ecosystem. She currently leads the Ungulate Ecology Research team, focusing on science to support bison conservation and wild horse and burro research across the west. She’s been studying the ecology of wild horses and burros since 1999, when she was first hired as a USGS field technician recording group composition of horse harems in the Pryor Mountain Wild Horse Range, Montana. Her current work includes investigating free-roaming horse competition with mule deer, and assessing mountain lion predation on free roaming horses in Nevada, as well as assessing fine scale foraging behavior of bison on the North rim of Grand Canyon National Park, Arizona, and the Great Sand Dunes National Park ecosystem of southern Colorado.

Can ruderal components of biocrust (mosses and cyanobacteria) be maintained under increasing threats of drought, grazing and feral horses?
Biological soil crusts (biocrusts) are a community of living organisms, like moss, lichen, and algae, covering soils in arid and semi-arid ecosystems, providing important ecological functions like carbon cycling and soil stabilization. Analyses show that biocrusts are negatively associated with the abundance of invasive annual grasses that are responsible for increasing fire across the Great Basin...
Wild horse and livestock influences on vegetation and wildlife in sagebrush ecosystems: Implications for refining and validating Appropriate Management Level (AML)
USGS researchers are conducting a comprehensive study of wild horse and livestock records across the greater sage-grouse range to investigate impacts on vegetation and wildlife (specifically, sage-grouse and songbirds). Researchers will use these results to evaluate Appropriate Management Levels for wild horse and burros, and projections of vegetation productivity under a changing climate.
Herbivore-Ecosystem Interactions
Data from these studies help inform management decisions regarding ungulates on public lands, typically in large, jurisdictionally complex landscapes. Recent work involves investigations on the effects of herd size and movements of elk, bison, and wild horses on various ecosystem components. Specifically, scientific efforts include quantifying interactions among herbivores, plants, and soils...
Where the Bison Roam: Public-Private Partnership Supports Potential Restoration
A little over one hundred years ago, plains bison were prolific in the Great American West. Reports describe herds containing thousands of animals migrating through the central and western states, totaling 20–30 million across their entire range. With commercial, unregulated hunting in the late 1800s came the rapid demise of bison to barely more than 1,000 by 18891. Recently, renewed interest in...
Non-invasive Genetic Sampling of Free-roaming Horses to Estimate Population Size, Genetic Diversity, and Consumption of Invasive Species
Molecular tagging is a new application of molecular genetic techniques to traditional mark-recapture methodology designed to address situations where traditional methods fail. In such studies, non-invasively collected samples (such as feces, feathers, or fur) are used as a source of DNA that is then genotyped at multiple loci such that each individual animal can be uniquely identified. Thus, each...
Counting America’s Wild Horses and Burros: Better Estimates for Population Management
The Wild Free-Roaming Horses and Burros Act of 1971, as amended, states that, "It is the policy of Congress that wild free-roaming horses and burros shall be protected from capture, branding, harassment, or death; and to accomplish this they are to be considered in the area where presently found, as an integral part of the natural system of the public lands (PL 92-195, Sec. 1331, Congressional...
Wild Horse and Burro Survey Techniques
Because population estimates drive nearly all management decisions pertaining to wild horses and burros, accuracy is important. Several widely used techniques exist for conducting aerial population estimates of wildlife, but individually, each has important limitations. Researchers at the U.S. Geological Survey, Fort Collins Science Center (FORT), are evaluating combinations of these techniques...
Elk and Bison Grazing Ecology in the San Luis Valley, Colorado
Managers need information on the grazing ecology of bison and elk in the Great Sand Dunes National Park and Preserve to develop science-based management alternatives.
Wild Horse and Burro Population Management
Wild horse populations often increase at high rates on U.S. western rangelands, which in turn can lead to habitat degradation. The U.S. Geological Survey and the Bureau of Land Management are cooperating on studies investigating the potential of fertility control drugs to reduce foaling rates. In addition, because nearly every management issue concerning wild horses depends on accurate herd counts...
America's Wild Horses and Burros—Research to Support Management
The wild horses that roam the west are feral descendents of domestic animals that either escaped from or were intentionally released by early European explorers and later settlers. As a result of both origin and contemporary management, the Spanish or Iberian influence remains strong in some wild horse populations (e.g., the Kiger, Pryor Mountain, and Sulfur Mountain herds). In other populations...
