As the Conservancy and partners work to implement best management practices, we will focus resources in priority areas, the benefits of which are easily quantifiable with existing science and offer the highest ecological return per conservation investment. These priority areas include Tier 1 watersheds (Cass River, Shiawassee River, and Pigeon/Pinnebog Rivers) where ecological and best management practices targets have already been established, with similar ecological targets to be established for Tier 2 watersheds (Pine & Chippewa Rivers, Kawkawlin River, and Sebawaing River).
