Description: Range of Variability (ROV) concepts – including Natural (NRV), Historic (HRV), Current (CRV), and Future (FRV) – are frequently used by the US Forest Service to help define land management goals. This webinar provides an introduction to ROV terminology and examples of how the Malheur, Umatilla, and Wallowa-Whitman National Forests in the Blue Mountains have applied ROV concepts during project planning when addressing key requirements of the Eastside Screens. The discussion includes overviews of tools commonly used to conduct ROV analyses.
