For nearly a century, pneumonia has contributed to massive declines and extinctions in bighorn sheep populations. Our consortium is taking a broad, interdisciplinary approach to investigating pneumonia by focusing on disease dynamics--learning how pneumonia moves through time and space to affect bighorn sheep.Read More
Since 1997, state and federal agencies and nongovernmental organizations have worked together to restore, study, and manage bighorn sheep in Hells Canyon. We combine these long term ecological data with field and laboratory research to ask new questions and understand problems from multiple perspectives.Read More
Our study area is the Hells Canyon ecosystem, a network of 5.6 million acres containing rugged canyons and mountains spanning Idaho, Oregon, and Washington. Bighorn sheep are native to Hells Canyon but died out when the area was homesteaded in the early 1900s. Today, about 800 bighorn sheep live here, and most populations are stagnant or have declined over the past 60 years, primarily due to pneumonia.Read More
