1. Measuring Rangelands

2. Uplands vs Riparian Vs Wetlands  Uplands = Drier areas on landscape that are only wet for short periods after precipitation events.

3. Uplands vs Riparian Vs Wetlands  Riparain = Vegetation adjacent to surface waters, such as streambanks and shorelines. Greener vegetation because of water sources

4. Uplands vs Riparian Vs Wetlands  Riparian Categorization: Lotic = associated with flowing water Lentic – associated with standing water.

5. Uplands vs Riparian Vs Wetlands  Wetlands = Areas with “hydric” soils that are permanently or seasonally saturated by water.

6. Vegetation Attributes  Plant Species or Type  Frequency  Density  Biomass  Cover  Structure

7. Plant Species or Type  Plant Species = genetically unique and closely related plants.  Life Form Grasses Grass-likes Forbs Shrubs Trees Jen Peterson K. Launchbaugh

8. 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%

9. Density  Number of individuals per unit area Plants/ft 2 Plants/hectare Etc.

10. 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

11. Biomass – can vary substantially

12. 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

13. Structure  Three-dimentsonal arrangement of a plant community.  Relates to: Hiding Cover Thermal Cover Wildland Fuels

14. 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 SpeciesLbs/acComposition Sagebrush15025% Wheatgrass40067% Lupine305% Yarrow203%
