  1. Natural Riparian Resources Water Vegetation Landscape & Soil

  2. Standard Checklist (lotic)

  3. Riparian/Wetland Vegetation Groups • Stabilizers • Colonizers • Increasers/Invaders

  4. Stabilizer Species

  5. Stabilizer group • Establish along streams, rivers, lakes, ponds, springs, & seeps • Strong, fibrous, deep root system • Rhizomatous • Provide protection against water’s energy

  6. Sedges (Carex) “Sedges have edges” Stem Triangular Solid Leaves 3-ranked

  7. Typical Habitat Saturated Soils Beaked Sedge (Carex utriculata) Formerly (Carex rostrata)

  8. Nebraska sedge(Carex nebarasensis)Emery Creek

  9. “Rushes are Round” Rushes (Juncus) Solid and Round or Compressed Leaves Alternate or 2-Ranked

  10. Typical Growth Pattern Baltic Rush or Wire Grass (Juncus balticus)

  11. Wire Grass Roots

  12. True Grasses Stem Hollow With Nodes and Intenodes Leaves 2-ranked

  13. Fowl Manna Grass(Glyceria striata) Blue Joint Reedgrass (Calamagrostis canadensis)

  14. Reeds Canarygrass(Phlaris arundicanacea)Little Wood River

  15. Woody Species (Willow, Alder, Birch, etc.)

  16. Willow Roots

  17. Alder

  18. Birch & Willow

  19. Willow

  20. Dogwood Red osier dogwood

  21. Colonizers • First to establish • freshly deposited soil • shallow open water • barren areas • Root systems • stoloniferous or rhizomatous • shallow and relatively weak • Critical to recovery

  22. Spike Rush Brook Grass

  23. Short-awned Foxtail

  24. Water-cress (Rorippa naturtium-aquaticum)

  25. Coyote (Sand Bar) Willow (Salix exigua)Teton River

  26. Cottonwood(Populus spp.)South Fork Snake River

  27. Increasers/Invaders • Tolerant of heavy grazing • Increase with heavy grazing • Low growing points • Shallow, less massive root systems • Less protective of streambanks against water’s energy • Noxious weeds

  28. Kentucky Bluegrass and Red Top(Poa prentensis and Agrostis stolonifera) East Fork Castle Creek

  29. Leafy Spurge Purple Loosestrife

  30. 6) There is diverse age-class distribution of riparian-wetland vegetation (recruitment for maintenance/recovery) • Multiple age-classes usually indicate that riparian-wetland areas can recover or maintain themselves • At least 2 age-classes should be present • One of the age-class should be young • Older age classes can persist in degraded conditons • This is presence/absence question, not an amount

  31. Are there two or more age classes of stabilizer riparian/wetland species present within the riparian area?

  32. Are there two or more age classes of stabilizer riparian/wetland species present within the riparian area?

  33. Are there two or more age classes of stabilizer riparian/wetland species present within the riparian area?

  34. 7) There is diverse composition of riparian-wetland vegetation (for maintenance/recovery) • Diverse composition of riparian-wetland vegetation allows for recovery and maintenace • This is a presence/absence question not amount • At least stabilizing species present

  35. Are there at least two stabilizer riparian/wetland species present within the riparian area?

  36. Are there at least two stabilizer riparian/wetland species present within the riparian area?

  37. Are there at least two stabilizer riparian/wetland species present within the riparian area?

  38. 8) Species present indicate maintenance of riparian soil moisture characteristics • Indicators that water table level is being maintained or raised • Incised Channel • Aggrading Channel • Riparian Vegetation • Obligate Wetland (OBL) > 99% • Facultative Wetland (FACW) 67% to 99% • Facultative (FAC) 34% to 66% • Upland Vegetation • Facultative Upland (FACU) 67% to 99% • Obligate Upland(UPL) > 99%

  39. Are stabilizing riparian/wetland species regenerating? • Are upland species encroaching into the riparian/wetland area? • Has the channel incised leaving remnant riparian/wetland vegetation on the terrace? • Is there a water source independent of the stream? (Refer to Question 4)

  40. Are stabilizing riparian/wetland species regenerating? • Are upland species encroaching into the riparian/wetland area? • Has the channel incised leaving remnant riparian/wetland vegetation on the terrace? • Is there a water source independent of the stream? (Refer to Question 4)

  41. Are stabilizing riparian/wetland species regenerating? • Are upland species encroaching into the riparian/wetland area? • Has the channel incised leaving remnant riparian/wetland vegetation on the terrace? • Is there a water source independent of the stream? (Refer to Question 4)

  42. 9) Streambank vegetation is comprised of those plants or plant communities that have root masses capable of withstanding high stream flow events • Streambank Vegetation • Streambank is the part of the channel between bankfull and the streambed • Not a quantity question • Presence or absence • Obligate wetland or facultative wetland plants • Vegetation must be directly effecting the streambank.

  43. Streambank

  44. Are there stabilizing riparian species or riparian communities on the streambank?

  45. Are there stabilizing riparian species or riparian communities on the streambank?

  46. 10) Riparian-wetland plants exhibit high vigor • Determine if plants are healthy and robust • Sufficient leaf area for adequate food production • To actively reproduced • Grow strong deep root systems
