Bioengineering & “Funnel” Strategy Workshop @ Nichols Road Bridge, Onondaga Creek, NY A completed project needed some “tweaking” and veg. Top bank stone was removed the week before. All stone placement & planting occurred on Tuesday May 15, 2007.

County public works had straightened the stream WITH STACKED STONE WALLS (red lines), stream response WAS TO FLANK BOTH SIDES AT THE UPSTREAM END OF THE STRAIGHTENED HARDENED REACH

TWO-STAGE SLIT TRENCH TECHNIQUE Sketches by Derrick Dig the trench down into the capillary (vadose) zone {moist area above the permanent water table} Mini-Case study: 1 of 16 Spoil

TWO-STAGE SLIT TRENCH TECHNIQUE Take the last scoop of soil dug from the trench & place it back into the trench. Mini-Case study: 5 of 16
10
TWO-STAGE SLIT TRENCH TECHNIQUE Place willows & other water-loving species into loose soil at bottom of trench. They are then less likely to fall over when trench is backfilled. Mini-Case study: 7 of 16
11
Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Many hands get things done quickly, 2,740 plants planted in about 6 hours. That’s why they call it a workshop. Pix by Derrick
12
TWO-STAGE SLIT TRENCH TECHNIQUE Partially backfill the trench. Mini-Case study: 9 of 16
13
TWO-STAGE SLIT TRENCH TECHNIQUE Plant other species that require less water than the willow. In this case Sycamore & Red Osier Dogwood Mini-Case study: 11 of 16

21
Black Willow, Streamco Willow, Red Osier Dogwood & Sycamore were planted using the Slit Trench bioengineering method. 40 RPM container plants (7 species of trees & shrubs) were planted in the green oval areas. Plantings form a grid to flow. No matter how water flows through the project, it encounters rows of vegetation (Living Dikes)

Site – soil conditions are not ideal. Fill soil is a clay fragipan, when dry is like concrete. (Extremely dry summer -2007) Slit-Trench Black Willow-low mortality & outstanding growth, many 9 to 10 ft tall. When planted most 2-3 ft tall. Slit-Trench Streamco Willow-low mortality & outstanding growth, many 9 to 14 ft tall. Slit-Trench red osier dogwood – medium mortality, very good growth Slit-Trench & Slit Brush Layering Sycamore – high mortality, few if any survived Extreme Instant Shade Sycamore – all dead. Slit Brush Layering Willow – med mortality, decent growth, not very tall. Slit Brush Layering Red Osier Dogwood – low to medium mortality- dominating with lush growth. Pole Plantings in existing stone bank – low mortality, ~6-8 ft growth. RPM rooted stock trees – outstanding shrub growth, beaver browse on several trees, mixed performance on remainder of trees, many surviving not thriving, with a couple showing fast growth, 14-18 ft tall. RESULTS AFTER TWO GROWING SEASONS
