8o NATURAL RESEEDING AND MAINTENANCE 



is grazed first, and area B second. In order to provide thorough 

 planting of the seed area, area C is cropped closely — much 

 more heavily than areas A and B. In 1922, area C is 

 again grazed last, but this time moderately to avoid destruction 

 of the seedling plants; area B is grazed first; and area A second. 

 In 1923, area B is cropped closely according to the deferred- 

 grazing plan; area A is grazed first; and area C second. In 



1924, area B is again reserved for moderate grazing after 

 seed maturity; area C is grazed first; and area A second. In 



1925, area A is selected for deferred grazing and is cropped 

 closely; area C is grazed first; and area B second. In 1926, 

 area A is moderately grazed after seed maturity ; area B is pas- 

 tured first; and area C second. After that, the plan, as indi- 

 cated in the table, would be repeated, except that in 1927 area 

 B should be cropped first and area A second, in order to foster 

 the establishment of the young seedlings on the latter area. 



Although a knowledge of the individual pasture, particularly 

 of the character and density of the vegetation, type of soil, and 

 water facilities, is necessary in order to propose a judicious, far- 

 reaching grazing plan, it should not be difficult to apply the 

 principles here laid down. By the use of the plan proposed, all 

 parts of the pasture will be reseeded and the resulting increase in 

 the stand maintained indefinitely. 



Deferred Grazing on Range of " Winter Annuals." — The 

 foothill and valley (winter) ranges of CaHfornia, like those of 

 the Southwest, are admirably adapted to the growth of " winter 

 annuals " — plants like alfilaria, bur clover, and wild oats. 

 Although this type of cover completes its cycle of development 

 in one year, the seed germinates early in the winter, and growth 

 continues throughout the winter and spring. It is the practice 

 generally to begin cropping these lands early in the winter, 

 when the growth is well started, and continue until the herb- 

 age dries up in the spring. Where this practice has continued 

 year after year the lands are badly run down, chiefly because 

 of the failure of the more palatable plants to produce seed. 



In 192 1 tests were initiated on foothill (winter) ranges in 

 various parts of California, the object being to apply the de-
