Monitoring and Smolt
Trap
Mid Sound actively
conducts monitoring on its restoration projects over a
period of five years to identify project success and to
generate maintenance needs.
Monitoring
events consist of 4 steps:
- Set-up of
representative 12' circular test plots to survey
plant survival, percentage cover, and re-growth of
non-native plants.
- Establishment of
Photopoint locations to visually quantify changes
over time
- Creation of an
initial as-built map, which is being updated after
each monitoring event, noting changes to channel
morphology and habitat structure locations and
functions
- Wildlife
observations
After five years,
the value of continued monitoring is weighed against
project performance to determine the frequency and
duration of further monitoring.
Site maintenance needs
are generated from monitoring events and landowner obser-vations.
Site maintenance generally reduces over time as plants establish
themselves and habitat structures reach a state equilibrium.
Smolt Trap
The
Smolt Trap is the major tool for measuring the
success and function of our restoration projects. "Smolt" is
one of the life-stages of a juvenile salmon. This life stage
occurs when the juvenile salmon begins its migration from
freshwater to the estuary and adjusts to living in saltwater.
Our survey focuses on Coho. Coho stay in freshwater for about 2
years, before they start their big journey. Spring is the season
for migration, and our smolt trap stays in the water during the
months of April and May. With the help of a v-shaped weir, all
outmigrating Coho are forced to swim into a live box, where they
wait until they are released. The trap gets checked twice daily,
and the fish are counted, measured and identified before they
are released.
This method is commonly used to
evaluate juvenile coho use of winter rearing habitat.
