Efficient use of annual plants on cattle ranges in the California foothills efficientuseofan870bent Year: 1951 Figure 20.—Close utilization. This uniformly close utilization of annual-plant vegetation reduces the litter layer on the soil surface; conditions become distinctly unfavorable to plant growth. Growth during the winter is retarded and total yields in the spring are reduced, particularly on the very closely utilized bottom lands. The percentage of the dominant species in the plant cover may not be greatly changed, except in the swales; but minor weedy species increase on all sites. T
Efficient use of annual plants on cattle ranges in the California foothills efficientuseofan870bent Year: 1951 Figure 20.—Close utilization. This uniformly close utilization of annual-plant vegetation reduces the litter layer on the soil surface; conditions become distinctly unfavorable to plant growth. Growth during the winter is retarded and total yields in the spring are reduced, particularly on the very closely utilized bottom lands. The percentage of the dominant species in the plant cover may not be greatly changed, except in the swales; but minor weedy species increase on all sites. This degree of grazing is too close for efficient cattle production. Figure 21.—Moderate utilization. This patchy use of annual-plant vegetation maintains satisfactory soil conditions and a good plant mixture, without evidence of deterioration in either. Winter growth of forage and total yields in the spring are satisfactory although not as great as under lighter grazing. This is an efficient degree of utilization that provides satisfactory cattle production without waste of herbage.
