OOS 43 - Managing for Resilience In Wildfire-Prone
Ecosystems: Toward An Ecological Basis
B113, Oregon Convention Center
Organized by: NA Povak
Moderator: PF Hessburg
This session will focus on the concept of ecosystem resilience to
recurrent disturbances in fire-prone ecosystems of the western US,
and will include discussions on identifying multi-scale spatial controls
on fire regimes, quantifying anthropogenically-driven changes to
historical vegetation patterns, and incorporating landscape-level
management directed toward enhancing system resiliency.
