Yellowstone Wolf Impact Study
Between 1995 and 1997, Yellowstone National Park re-introduced into the Park a total of 41 wolves, after an absence of almost a century. It was the first deliberate attempt to re-introduce a top-level predator into a complex ecosystem. To date the project has been extremely successful: the population has grown to more than 400 in the ecosystem, and the wolves have affected the dynamics of the entire Yellowstone ecosystem. Understanding and monitoring their impact is one of the Park's highest priorities, and involves long-term research and monitoring both within the park and surrounding areas. The grant dollars will be used to help the park defray the following annual project costs from 2014 through 2017 for both aerial monitoring and wolf capture, tagging and research.
