Canopy Structure of a 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—...

Mixed-grass prairie canopy structure and spectral reflectance vary with topographic position.

Managers of the nearly 0.5 million ha of public lands in North and South Dakota, USA rely heavily on manual measurements of canopy height in autumn to ensure conservation of grassland structure for wildlife and forage for livestock. However, more comprehensive assessment of vegetation structure could be achieved for mixed-grass prairie by integrating field survey, topographic position (summit, ...
