In a groundbreaking study conducted by South Dakota State University's Department of Natural Resource Management, researchers are exploring the potential of using trained dogs to prevent bacterial outbreaks in South Dakota's bighorn sheep herds. A Deadly Discovery
In the summer of 2021, Badlands National Park was home to a thriving population of Rocky Mountain bighorn sheep. However, a sudden and mysterious die-off raised concerns among wildlife officials. After finding dead sheep infected with pneumonia-causing bacteria Mycoplasma ovipneumoniae, researchers feared a repeat of the devastating outbreak that nearly wiped out a herd in Custer State Park years before. The Fight Against Disease
The research team, funded by the National Park Service, has joined forces with other agencies to combat the current problem and prevent future outbreaks. With no vaccine or treatment available for the deadly bacteria, wildlife managers have resorted to testing and removing infected animals from the herd. Historic Struggles
The history of bighorn sheep in South Dakota has been tumultuous, marked by periods of growth and die-offs due to human activities and disease outbreaks. The current challenge lies in preventing contact between wild sheep and domestic livestock carriers of the deadly bacteria. Canines to the Rescue
To address this challenge, researchers are exploring the use of trained dogs to detect pneumonia in bighorns. By training shelter dogs to detect the bacteria through nasal swabs and scat samples, the team hopes to efficiently identify infected animals and prevent the spread of the disease within the herds. Future Solutions
By keeping livestock and wild sheep separate and tracking the movements of individual bighorns, researchers aim to prevent future outbreaks and protect the vulnerable population. Additionally, the use of livestock guardian dogs could be a potential solution to keep the groups separate and stop the disease from spreading. Hope on the Horizon
While the situation remains challenging, there is hope for the bighorn sheep population in Badlands National Park. With fewer sheep testing positive for the deadly bacteria, researchers believe they are making progress towards a healthy and growing population once again. The collaborative efforts and innovative methods being explored provide a glimmer of hope for the future of South Dakota's bighorn sheep.
