The bent willow pole method1

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

The bent willow pole method

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

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

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)

Make it a showcase

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?


The bent willow pole method

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???

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}
