Streambank Revegetation Zones

Zone Map

This graphic depicts zones of vegetation types that reflect typical moisture regimes along the transition from edges of lakes or rivers to the uplands. When revegetating these shorelines, use undisturbed plant communities for plant suggestions. The following listing provides generalized plant material recommendations for each zone. Many of these species can be found in more than one zone. Commercial availability of species varies.

Zone 1

  • Water sedge - Carex aquatilis
  • Lyngbyaei sedge - C. Lyngbyaei (brackish water)
  • Bulrush - Schoenoplectus sp., Scirpus microcarpus

Zone 2

Hydric-mesic soils - fluctuating water levels subject to boat or wind driven waves:

  • Egan American Sloughgrass - Beckmannia syzigachne
  • Bluejoint reedgrass - Calamagrostis canadensis

  • Kenai Polargrass - A. latifolia
  • Beach Wildrye - Leymus mollis

  • Undergreen Willow - S. commutata

Zone 4

Mesic soils - seasonally variable moisture regimes:

  • Prickly Rose - Rosa acicularis
  • Raspberry - Rubus idaeus
  • Labrador tea - Ledum sp.
  • Dwarf Birch - Betula nana
  • Poplar/Cottonwood - Populus sp.
  • Gruening alpine bluegrass - Poa alpina

Zone 5

Mesic - xeric soils - upland benches:

  • Paper Birch - Betula papyrifera
  • White Spruce - Picea glauca
