Riparian-Wetland Vegetation Assessment Guide

This guide assesses the age class diversity, composition, and vigor of riparian-wetland vegetation to determine recruitment, maintenance, and recovery indicators. It evaluates moisture conditions, vegetation stability, frost impacts, and microsite characteristics.

  1. LENTIC VEGETATION

  2. LENTIC ASSESSMENT FORMVEGETATIVE

  3. 8. There is a diverse age-class distribution of riparian-wetland vegetation (recruitment for maintenance/recovery) • Purpose: • Determine if sufficient age classes are present to indicate recruitment is occurring • Does not mean all age-classes are present • Usually two age classes are sufficient

  4. Age Class Mature shrubs Young shrubs III

  5. No Age Class Is there a diverse age class of riparian-wetland vegetation?

  6. 9. There is diverse composition of riparian-wetland vegetation (for maintenance/recovery) Alder Red osier dogwood Sedge Bullrush Cattails

  7. 10. Species present indicate maintenance of riparian-wetland soil moisture characteristics • Purpose: • Indicate the presence of a shallow water table • It does not ask if there is enough plants • Only that the plants indicate the maintenance of riparian-wetland moisture conditions

  8. Wetland Plants Indicator Categories • Obligate Wetland (OBL) >99% in wetlands • Facultative Wetland (FACW) 67-99% • Facultative (FAC) 34-66% • Facultative Upland (FACU) 1-33% • Obligate Upland (UPL) <1% JUAR2=75 CANE2=99 POPR=50 BRTE=1 ROWO=25

  9. 11: Vegetation is composed of those plants or plant communities that have root masses capable of withstanding wind events, wave flow events, overland flows (e.g., storm events, snowmelt) • Purpose: • Do shorelines of open water areas and soil surface in seeps & wet meadows have the right plant communities?

  10. 12: Riparian-wetland plants exhibit high vigor • Low vigor can be illustrated by: • Relative size, productivity or reproductivity • Necrosis (tissue degeneration) • Color (chlorosis) • Wilting

  11. 13: Adequate riparian-wetland vegetative cover is present to protect shoreline/soil surface and dissipate energy during high wind and wave events or overland flows. • Purpose: • Is there a sufficient amount of stabilizing vegetation Yes Softstem bulrush Three-square bulrush

  12. 13: Adequate riparian-wetland vegetative cover No

  13. 14: Frost or abnormal hydrologic heaving is not present • Purpose • Determine whether frost or hydrologic heaving is at a normal or aggravated rate No

  14. No

  15. 15: Favorable microsite condition (i.e., woody material, water temperature, etc.) is maintained by adjacent type characteristics • Purpose • Determine if microsite conditions are necessary for proper functioning, and if so, whether adjacent site characteristics are maintaining those conditions Absent forest does not provide shade, or logs for sundews No

  16. No
