Environmental Science - Conservation and Restoration Ecology

Conservation and Restoration Ecology Pathway

students researching near a streamThe Conservation and Restoration Ecology Pathway (CRE) links the study of conserving and maintaining ecological systems and their elements with the recovery of damaged ecosystems. The combination of conservation and restoration creates a practical framework for managing natural resources and landscapes. Fundamental understandings of ecosystem components and processes are used to foster and sustain native species, ecological communities, and ecosystems.
