Root Systems of Four Desert Grassland Species on Grazed and Protected Sites

Root systems of species of Aristida, Bouteloua and Trichachne were restricted to the upper 7 inches of soil, with depth penetration of roots influenced by characteristics of the soil. Grazing affected root development by reducing the amount of branching of first-order roots and, in 2 species of Bouteloua, by decreasing total root density. Root diameter was not affected.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
