Measuring Rangelands Uplands vs Riparian Vs Wetlands Uplands = Drier areas on landscape that are only wet for short periods after precipitation events. 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 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
Plant Species or Type Frequency Density Biomass Cover Structure Plant Species or Type Plant Species = genetically unique and closely related plants.

K. Launchbaugh K. Launchbaugh 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 Number of individuals per unit area Plants/ft2 Plants/hectare Etc. 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 Biomass can vary substantially
Cover Proportion of ground surface covered by vegetation or other objects including: rocks litter (dead plant matter)
moss bare ground Measured with points or plots Structure Three-dimensional arrangement of a plant community. Relates to:
Hiding Cover Thermal Cover Wildland Fuels Plant Composition A calculation based on proportions of biomass or cover. Proportion (%) of various
