Range managers have long known that overgrazing changes the plant composition of pastures.
As a result, plant species are referred to as increasers, decreasers or invaders. This is a reference to their reaction to years of overgrazing (generally by cattle as opposed to sheep).
By knowing how a few common species react to grazing and monitoring their abundance in pastures, managers can improve forage quality, quantity and, consequently, profits," says Chuck Lura, rangeland specialist at North Dakota State University’s Central Grasslands Research Extension Center near Streeter.
