They point out that any grazing which removes over 25 to SO per cent of the desert plant herbage after about April 1 must be regarded as dangerous. It Is especially serious when forage is removed during the winter and again the spring. Never should more than SO per cent be removed in either season, as might occur when sheep graze winter Fange until late spring or when cattle graze desert ranges year long. Over a r period the 'checked both the et. feet of season of harvesting and the Intensity of harvesting on seven species of long-live- d perennial forage planta common to typical salt desert ranges In western Utah. . two-yea- 'The researchers removed parts of the plants by hand in a- manner simulating the way they would be harvested by grazing entasis. In the first phase, car. ried on from 1955 to 1957, they checked the effect of removing 25, 50 and 75 per cent of the herbage at four different seasons about November 1, January 1, March 1 and May 1 repeated at two different locations 90 miles apart. In the second phase from 1968 to 19(1 they added a third location and clipped more severe, ly, removing SO, 60 and 90 per cent of the foliage. Harvest seasons were changed to Include fall, winter, early spring and late spring. They considered early apring as about the time new growth first appeared, around April 1, and late spring as about the time 20 per cent of the new growth had been produced, usually around May 1. In the flint phase of the study, spring harvesting was much more detrimental than that oT the other three seasons. It caused about 89 per cent more death lorn of plants and resulted In 54 per cent more reduction In also of the remaining plants than did the other seasons. In the second study, the late spring grazing appeared to be considerably more detrimental than early apring graslng.
