Annual plants make up 90 to 100 percent of the forage on more 

 than 25,000,000 acres of foothill and valley ranges in California. A 

 healthy, productive range condition in these annual types depends on 

 the amount of old forage left on the ground at the end of the grazing 

 season. This residue forage determines both the amount and the quality 

 of forage produced in following years. An adequate cover of vegetation 

 serves to protect the soil from the direct action of rain, wind, sun- 

 shine, and other forces that may cause erosion or lower the fertility 

 of the soil. It not only protects the soil but helps to build it up. 

 Too little cover will permit the range to deteriorate. Too much means 

 forage waste.
