1. Assessing the Cumulative Effects of Forest Management: Research in the Mica Creek Experimental Watershed

2. Motivation Research and Management Needs Will increased runoff due to logging destabilize streams? Data from “typical” managed forestlands –Second growth –Contemporary management practices –Watershed scale Interdisciplinary connections Mechanistic understanding of processes Integrated, spatially-explicit management tools Enter Mica Creek…

3. MCEW Location  Unique climate region  Continental/Maritime

4. MCEW Study Design  Initiated 1990  6 years calibration period  4 years post-roads  4 years post-harvest  50% canopy removal  Clearcuts  Partial Cuts  Paired & nested watersheds

5. Pre harvest 2000Post harvest 2002

6. Current and Future Directions 1990: Potlatch Core Study Initiated (McGreer) 2003: LIDAR investigations (USFS Agenda 2020: Gessler, Hudak, others) 2003: Modeling cumulative effects of disturbances (USFS RMRS: Boll & Link) 2003: Simulation of changing hydrologic regimes (USDA NRI: Link) 2004: UI Collaborative Working Forests (Federal Appropriation: Link, Braatne, Kavanagh, Han, Marshall) 2005: CO 2 and H 2 O Interactions (NSF-EPSCoR: Humes, Marshall, Cook, Kavanagh, Qualls, Walden)
