Juvenile rearing and adult migration is not possible in the lower Yakima River for much of the summer due to extreme high temperatures. Purchasing development rights would lead to restoration and protection of critical riparian habitat, which in turn would improve water quality and spawning/rearing habitat by ensuring riparian function is maintained.

Specific measureable objectives
Pre- and post- project implementation riparian canopy closure would be quantified.
Improving riparian canopy closure will increase rearing habitat function and improve water quality.
Underlying assumptions or critical constraints
Changes in riparian canopy will be determined with a densiometer.
Brief schedule of activities
The project would begin by notifying landowners of the program by fliers distribution. Meetings with interested landowners would occur. A rating system would be used to determine priority properties for purchase. Conservation easement language would be drafted with the assistance of an attorney. Easements would begin to be secured in year two. Further promotion of the project would occur through additional mailings. In year three, the time allocated to the project would be decreased to 0.25 FTE. The project would conclude after year five.
From past research fish managers know that summer maximum temperatures in the lower Yakima River are too high to support salmonids. This effectively truncates the out migration of zero-age spring chinook, and prevents the reintroduction of stocks that require this reach during the critical season. This project would redress rearing habitat function through increasing riparian canopy closure, reducing sedimentation, increasing in-channel habitat complexity and improving water reducing substrate embeddedness.
The lower 100 miles of the mainstem Yakima River cannot support anadromous fish because of lethal temperatures.
Summary of expected outcome
Native riparian vegetation density will increase. In turn, water quality will improve because canopy closure will improve. Ultimately, summer maximum temperatures will decrease. Ultimately the project will be used as a local demonstration area to encourage additional landowners to protect and restore streams.
Dependencies/opportunities for cooperation
Conservation easement purchase would be coordinated with the county assessors office, and the Yakima Greenway Foundation.
Canopy closure would be monitored over time.
