The Sickledrat: A Circular Quadrat Modification Useful in Grassland Studies

Abstract

A sickle-shaped modification of a circular quadrat has been used advantageously in tall-grass rangeland production studies in northeast Oklahoma. The main advantages of this quadrat are the reduction of the area concept bias in quadrat placement, ease of quadrat placement, reduction of perimeter decisions, and facilitation of precision clipping at various heights above the soil surface.
