~Spawner
Surveys~
Volunteers
and staff perform spawner surveys to count salmon returning to project sites.
Surveys begin below the project site and continue upstream until well above
the project site. Project sites are walked once per week during the spawning
season. Each week the total number of live adult salmonids, salmonid carcasses,
and redds are counted and recorded by species. Tails are clipped to avoid
counting the same carcass in subsequent surveys. Every redd is counted, measured,
and flagged. A flag is tied directly above the redd with the date the redd
was recorded written on the flag. This prevents redd disturbance during future
surveys and double counting.
Monitoring Coordinator Kevik Rensink shows volunteers how to measure a redd, or salmon nest. |
