THE BENT WILLOW POLE METHOD

1. THE BENT WILLOW POLE METHOD

2. BIOENGINEERING: The use of living plant materials to stabilize streambanks Most bioengineering gives Mother Nature a jump start (plant those native species, tall, short, fast growing, slow growing, etc.)

4. THE BENT WILLOW POLE METHOD • A John McCullah invention • This technique is used to integrate large willow poles behind (landward of) a riprap protection scheme • Poles can be laid on the bank (butt ends in water or vaidose zone), covered with riprap, then the upper ends bent to a vertical position, then rocks wedged behind pole to keep pole oriented vertically • Allows willows to grow in some areas (UP BANK) where naturally it might be too dry for vigorous willow growth Mini case study: 1 of 25

5. Unique willow pole transportation Mini case study: 2 of 25

6. This method invented by John McCullah! From: www.E-SenSS.com Self-Filtering Stone can be used in this application Mini case study: 3 of 25 Riprap can also be soil choked, seeded, planted

7. Option LPSTP weighted toe with paved midbank– Upper bank sloped & vegetated Grade the bank to the appropriate angle Locked Logs (not used in John’s example) would be angled downstream 30 degrees Mini case study: 4 of 25

8. Option LPSTP weighted toe with paved midbank– Upper bank sloped & vegetated Grade the bank to the appropriate angle Horizontal Root Wads can also be used, flow should be straight into the root wad (in compression) Mini case study: 5 of 25

9. LPSTP weighted toe with paved midbank– Upper bank sloped & vegetated Install gravel-cobble granular filter Mini case study: 6 of 25

10. LPSTP weighted toe with paved midbank– Upper bank sloped & vegetated Install willow poles (to be used as the Bent Willow Pole Method) Mini case study: 7 of 25

28. DONE Mini case study: 24 of 25

29. MAKE IT A SHOWCASE!! • Anything that should be along the stream corridor that is missing? • Diversity: native plant assemblage (large variety of species and age) • Native plants to out-compete non-natives? • Wildlife / bird attractors-nesting • Food sources: native pear-apple, crabapple, oak, berries • Vines? Ground cover? Trumpet vines? • Hummingbirds - butterflies - pollinators-insect attractors? • Year round color: budding trees in spring (dogwood, redbud,) colorful flowering plants in summer (native azaleas, mountain laurel), fall and winter color (maples), trees that have unusual colored leaves-berries in fall winter? • Good urban plants? Pollution tolerant?

30. Adventitious Rooting Plants(when trunk or branches are in contact with soil the plant will sprout roots) • Banker’s Willow-Salix x cottetii, Streamco Willow-Salix purpurea, Black Willow-Salix nigra, Pussy Willow-Salix discolor, & Crack, Autumn etc. • Red Osier Dogwood-Cornus stolonifera • Silky Dogwood-Cornus amomum • Buttonbush-Cephalanthus occidentalis • Sycamore-Platanus occidentalis • Cottonwood-Populus deltoides • Box Elder-Acer negundo • Speckled Elder-(bark was scarred)- Alnus rugosa • Elderberry-Sambucus Canadensis • Elm-Ulmus Americana • Bois d'arc, Mock Orange, Bow Wood, Hedge Apple, Horse Apple, Osage Orange- all are Maclura pomifera.  • River Birch- (Betula nigra) • Black Locust- (Robinia psedoacacia) • Northern Catalpa- (Catalpa speciosa) • Mulefat- (Baccharis salicifolia) Anyone know of any others???

31. ADVENTITIOUS ROOTING PLANTS NEED TO BE PLANTED WHEN THE PLANTS ARE DORMANT {AFTER THE LEAVES HAVE DROPPED & BEFORE THE LEAF BUDS APPEAR IN THE SPRING}
