Bundle Up!

This week, students from Deer Park Academy joined SOLV at Willow Creek to learn a little bit more about bioengineering techniques.  The last time they visited the site, students installed live willow stakes in the banks to halt erosion and create shade.

This week, we tried a different stream bioengineering technique called fascine bundles or wattles; these are bundles of live and dead plant material that are bound together with twine and placed in a shallow trench.  We used long and short willow stakes harvested from mature trees on-site and installed them on the edge of the waterway; students alternated the tips and buds of the stakes to ensure even growth.  When they root out, these bundles will create a great system of varying root depths to hold onto the soil and will grow to shade the waterway to lower the stream temperature.  All of this without machinery or invasive materials!
