Degraded Channel and Riparian Areas Degraded Channel Structure and Complexity
Leach Botanical Gardens is a City of Portland Parks and Recreation property managed by Leach Garden Friends. We have been working with a diverse group of partners including 2 local schools to remove invasive plants from 5 acres along Johnson Creek. This project will address instream and floodplain habitat restoration by placing log habitat structures and enhancing floodplain connectivity by enlarging a .15 ac wetland area to a .3 acre wetland with seasonal connectivity to the creek. This stretch of Johnson Creek has a full riparian canopy along both sides of the creek, but lacks instream habitat diversity and floodplain connectivity.

Targeted Performance Measure

  • Large Wood Placement: 600.00 lf
  • Off-Channel Wetland Area Increase: 6,500.00 sq ft

Focal Species

  • Coho
  • Pacific Lamprey
  • Spring Chinook
  • Steelhead
