uplands vs riparian vs wetlands
Uplands vs Riparian Vs Wetlands
  • Uplands = Drier areas on landscape that are only wet for short periods after precipitation events.
uplands vs riparian vs wetlands1
Uplands vs Riparian Vs Wetlands
  • Riparian = Vegetation adjacent to surface waters, such as stream banks and shorelines.
    • Greener vegetation because of water sources
uplands vs riparian vs wetlands2
Uplands vs Riparian Vs Wetlands
  • Riparian Categorization:
    • Lotic = associated with flowing water
    • Lentic – associated with standing water.

Uplands vs Riparian Vs Wetlands
  • Wetlands = Areas with “hydric” soils that are permanently or seasonally saturated by water.
vegetation attributes
Vegetation Attributes
  • Plant Species or Type
  • Frequency
  • Density
  • Biomass
  • Cover
  • Structure
plant species or type
Plant Species or Type
  • Plant Species = genetically unique and closely related plants.
  • Life Form
    • Grasses
    • Grass-likes
    • Forbs
    • Shrubs
    • Trees

frequency
Frequency
  • How often a plant occurs within a sampled area
  • Proportion (%) of times a plant occurs in the total number of plots examined.

Example: If dandelions occur in 2 out of 5 plots examined = Frequency of 40%

density
Density
  • Number of individuals per unit area
    • Plants/ft2
    • Plants/hectare
    • Etc.
biomass
Biomass
  • Total weight of living organisms, including plants and animals, for a given area
    • Usually expressed as kg/ha or lbs/acre
    • In range assessment refers to just plants, does not usually include weight of animals per area.
    • Determined by clipping and weighing
cover
Cover
  • Amount of ground surface covered by vegetation or other objects including:
    • rocks,
    • litter (dead plant matter)
    • moss
    • bare ground
  • Measured with points or plots
structure
Structure
  • Three-dimentsonal arrangement of a plant community.
  • Relates to:
    • Hiding Cover
    • Thermal Cover
    • Wildland Fuels
plant composition
Plant Composition
  • A calculation based on proportions of biomass or cover.
  • Proportion (%) of various plants (or life form) in relation to total plant biomass or cover
