  1. The Slit Brush Layering Method

  2. THIS METHOD IS A DAVE DERRICK DISCOVERY (DDD)

  3. SLIT BRUSH LAYERING (SBL) - BANK REVEGETATION: SBL replaces the more intrusive Brush Layering (total bank deconstruction, then rebuilt with layers of adventitious unrooted live poles between layers of semi-compacted soil). With SBL the track hoe bucket digs into the bank at a steep angle, lifts a few inches, live poles are inserted into the slit, then bucket pulls out & packs soil with back of bucket.

  4. 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 planting occurred on Tuesday May 15, 2007.

  5. THE PLANT MATERIALS Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  9. LAYOUT & PLAN A project goal was to quickly & densely revegetate the left descending bank of Onondaga Creek upstream of the county bridge. A minimal stone toe was already in place. Dormant unrooted live poles (Streamco Willow, Redosier Dogwood, & Sycamore) were deep-planted with a track hoe. Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  11. Several dozen Black Willow & Red Osier Dogwood live poles were planted using the Slit Brush Layering bioengineering method. Two 60 ft long rows were installed on the left descending bank of Onondaga Creek (denoted by the red lines ).

  12. Two rows of Slit Brush Layering will be located along the black lines. Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  13. TWO LAYERS OF “SLIT” BRUSH LAYERING Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  15. This is almost a Live Siltation retrofit above an existing stone toe. Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Hoe bucket digs 2-3 ft into the bank at a steep angle, lifts a few inches, then live unrooted poles are placed in the slit at a rate of 3 poles per ft.

  17. First Slit Brush Layer (willow) in place, second layer (willow, dogwood, Sycamore) being installed. Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  18. Installing second layer of Brush Layering (willow, dogwood, sycamore mix). Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  19. Looking US at both layers of completed Slit Brush Layering. Upper bank loose & rough so rain water will soak in (shallow groundwater)& not form rills. Pix by Bill Frederick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  23. 2 YEARS & 1 MONTH AFTER PROJECT COMPLETIONPhotos by Derrick JUNE 18, 2009

  24. 2 YEARS & 1 MONTH LATER-Left bank & overbank vegetation is robust & lush & fully functioning. Slit Brush Layering is between arrows. 2 YEARS & 1 MONTH LATER-Onondaga Cr.@ Nichol Rd Bridge-DERRICK 6-18-09

  25. 2 YEARS & 1 MONTH LATER-Looking @ left bank Slit Brush Layering. Vegetation is robust & lush & fully functioning. Red Osier Dogwood is dominating the Slit Brush Layering on the bank 2 YEARS & 1 MONTH LATER-Onondaga Cr.@ Nichol Rd Bridge-DERRICK 6-18-09

  26. 2 YEARS & 1 MONTH LATER-Looking US @ 2 rows of Slit Brush Layering. First year was all willow, then dogwood dominated (took it a year to put down roots). All Sycamore died. 2 YEARS & 1 MONTH LATER-Onondaga Cr.@ Nichol Rd Bridge-DERRICK 6-18-09

  27. Site – soil conditions are not ideal. Fill soil is a clay fragipan, when dry is like concrete. (Extremely dry summer -2007) 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. Slit Brush Layering Sycamore – high mortality, few if any survived RESULTS AFTER 2 GROWING SEASONS-From Mark Schaub
