The Lower Columbia Fish Advisory Board defined eight conservation measures to guide protection of salmonids. The conservation measures are tailored to southwest Washington.
Clark County uses BMP’s to describe the mitigation necessary to achieve the fish recovery plan. Because the Fish Recovery Board conservation measures only address streams and rivers, Clark County defined additional conservation measures to address terrestrial Priority Habitats and Species (PHS).
The conservation measures are:
- Protect stream corridor structure and function
- Protect hillslope processes
- Restore floodplain function and channel migration proceses in the mainstem and major tributaries
- Restore degraded hillslope processes on forest, agricultural, and developed lands
- Restore riparian conditions throughout the basin
- Restore degraded water quality with emphasis on temperature impairments
- Restore channel structure and stability
- Create/restore off-channel and side-channel habitat
- Minimize impacts on Priority Habitat Species
- Avoid or minimize clearing mature or old growth forests
- Avoid removing snags/downed wood
- Implement avoidance, enhancement and seed dispersal recommendations for Oregon White Oak Woodlands (WDFW, 1998)
- Avoid modifying caves, cliff, and talus habitat
- Avoid clearing native vegetation from urban natural open spaces
- Avoid or minimize impact wood duck habitat
