I think it is wise to tell others to do thorough homework regarding APR. If you are a Montanan with ties to the farming/ranching lifestyle or even someone from elsewhere who respects those who raise stock and grow food in Eastern Montana, be sure you know what the goal of APR is. Be sure you understand their methods to achieve their goals and how this will affect the lives of locals, many of whom are 4th or 5th generation farmers and ranchers on their land - land that APR wants.
The American Prairie Foundation (aka American Prairie Reserve) is surely one of the most visionary conservation organizations ever. It is acquiring and restoring lands on the eastern Montana Great Plains with a goal of connecting to and adding to the Charles M Russell National Wildlife Refuge and the Upper Missouri River Breaks National Monument, eventually creating a 3.5 million acre natural area, resembling what this region was like in the days of Lewis and Clark. APF is a well run organization. It has a strong list of supporters and scientific advisors. It has encouragement from the World Wildlife Fund and the National Geographic Society.
