BACKGROUND:

The effects of these projects have periodically been monitored over this timeframe. Large wood distribution has been inventoried annually since 2007 and additional habitat monitoring has occurred once every five years. These monitoring activities will be repeated staring in 2026 through 2030 using the previously used protocols.
