Changes in Prairie Plant Composition

Abstract

In an excellent range condition, the bluestems (big and little) decreased 15% in abundance from 1949 to 1964. Kentucky bluegrass increased to 42% in the good condition class. In fair condition all the bluestems remained, but in low vigor. The primary reason for the changes was an addition of a livestock pond, which created additional grazing pressure, and favorable climatic condition for Kentucky bluegrass.
