Vegetative Response Following Pinyon-Juniper Control in ArizonaO'Rourke, J. T.; Ogden, P. R. (Society for Range Management, 1969-11-01)Mean percentage calcium carbonate levels of near 13% in the surface foot of soil and low pinyon-juniper crown cover (13% and 26%) were associated with no increase in perennial grass herbage production four to five years after pinyon-juniper control in north-central Arizona. Both percentage calcium carbonate in the surface soil and percentage pinyon-juniper crown cover are expressions of the long-time moisture regime of a site and may be good indices for predicting potential understory response which might be expected from pinyon-juniper control.
