Studying a charismatic apex predator of Yellowstone National Park is continually a fascinating, rewarding, and humbling experience. The Wolf Project goals and research constantly adjusts to current technology, National Park Service and veterinarian guidance, and the wolves themselves. Because of the team of people dedicated to the welfare of Yellowstone’s wildlife, radio-collaring remains a safe and effective way to study the mysterious and wild gray wolf. Through the 24 years of wolf research in Yellowstone National Park, many questions have been answered, and more have emerged, about wolf ecology, their societies, =, and vulnerabilities to humans and human-altered changes to ecosystems. The curiosity, and the science, continues.
