Upper Abernethy Creek Tributary Restoration
Project Overview
Basics
Upper Abernethy Creek Tributary Restoration
Planning/Design
Improve instream and riparian conditions along 1924-feet of stream channel in an unnamed tributary to upper Abernethy Creek. Extensive blackberry coverage risks compromising the remaining riparian area as it spreads along the stream channel. Cool water temperatures in summer can be protected and even improved through the removal of invasive blackberry, maintenance of the invasive vegetation removed, and planting of appropriate riparian plants/trees for the area.

Focal Species
Focal Species
The addition of large wood will improve spawning habitat for coho by aiding in retention of spawning sized gravel that currently moves through the system during larger storm events. Large wood will also improve overhead cover that benefits both adults and juveniles. Strategic placement of logs will also increase connection between the stream and its floodplain where potential for coho rearing habitat improvements exist.
Pacific lamprey are found in spawning and juvenile fish surveys throughout the Abernethy Creek watershed, including the reach where wood will be placed via this project. Adult lamprey are expected to benefit from instream restoration actions in a similar manner as other native migratory fish in the system (improved spawning and rearing conditions). Lamprey ammocetes will benefit from improved connectivity between the stream and floodplain where rearing ammocetes will lie in substrate.
The addition of large wood will improve spawning habitat for winter steelhead by aiding in retention of spawning sized gravel that currently moves through the system during larger flow events. Large wood will also improve overhead cover that benefits both adults and juveniles. Strategic placement of logs will also increase complex habitat (pools, undercut banks) within the stream channel where the primary rearing habitat for juvenile winter steelhead exists.
