UNITED STATES DEPARTMENT OF AGRICULTURE-. Efficient Use of Annual Plants on Cattle Ranges in the California Foothills By, J. R. Bentley„ range conservationist, and M. W. Talbot, associate director,1 California Forest and Range Experiment Station 2 INTRODUCTION The California foothills (fig. 1) comprise the most important range area within the State. These lands border the great Central Valley and enclose numerous smaller valleys within the Coast Ranges. Primary use of foothill range lands is production of livestock. This use is closely associated with the highly intensified valley agriculture, which supplies hay, grain, and agricultural byproducts to supplement range forage and furnishes seasonal pasturage for livestock carried part of the year on foothill range. Also, some of the livestock are grazed during the summer in the mountainous lands above the foothills. But by far the greatest part of the State's range grazing capacity is in the foothills. The foothill area has relatively mild, wet winters and hot, dry summers. Thus, some green forage is available during the fall and winter, plant growth is at its height during the spring, but the plants are dry during the summer and early fall. Annual plants dominate the herbaceous cover and occur with varying amounts of bunchgrasses and other perennial species. This cover is found over the grass and woodland-grass vegetative types, as well as the more open phases of the chaparral. 1 Credit is due to two former forest ecologists of the California Forest and Range Experiment Station: F. G. Renner, who was in charge of planning, establishing, and supervising the forage experiments in 1934-35, and H. H. Biswell, in charge of the experiments 1936-40. Assistance in sampling of forage and in compilation and analysis of data was obtained from members
