Evaluation of Sampling Techniques on Tall-Grass Prairie

Quantification of Climate Conditions Important to the Tall Grass Prairie

The geologic history of the tall grass prairie in central North America reveals the prairie began developing 10,000 years ago after the Pleistocene ice sheets had retreated into Canada. The long-lived triangular shaped prairie survived several climatic shifts during the Holocene. Scientists have studied the anomaly—grasses where many climate conditions indicate forests should have been growing—...

Comparison of Vegetation Sampling Procedures in a Disturbed Mixed-Grass Prairie

Researchers currently use many different vegetation sampling methods in grassland systems (Shmida 1984, Stohlgren and Bull 1998, Barbour et al 1999). Each method examines the landscape at a slightly different grain (unit of observation) and extent (total area under study). Variation of study resolution (grain and extent together) and sampling frequency influences estimates of species richness a...
