58 RESEEDING WESTERN GRAZING LANDS 



the enclosure is carried for a considerable distance over the ad- 

 jacent area. In two or three seasons young plants are seen 

 radiating from the central " oases." 



Every precaution possible should be taken to avoid the de- 

 struction of all the native seed plants. If the lands are denuded 

 of vegetation, nature is put to such a disadvantage that 

 it may be impossible to replace in years what required only 

 two or three seasons to destroy. 



QUESTIONS 



1. Discuss the results of plant introduction on arid native western grazing 

 grounds. 



2. Discuss the physical conditions peculiar to mountain range lands as 

 related to the growth of cultivated forage plants. 



3. Name five plants that are reported to have given the best results in 

 reseeding mountain meadows. 



4. When is the best season to sow (a) In the Northwest? WTiy? (b) In 

 the Southwest? Why? 



5. Name five common causes of failure in reseeding mountain land. 



6. What cultural implements would you recommend for use in preparing 

 the seedbed and covering the seed? 



7. How should the seed be scattered? 



8. (a) Why is it important that the seed be covered? (b) How may this 

 best be done on the range? 



9. (a) Discuss elevation as a limiting factor in range reseeding. (b) At 

 how great an elevation is it practicable to seed (i) in the Northwest, (2) in 

 the Southwest? 



10. Name three important characteristics which a forage plant that is 

 to be seeded on the range should possess. 



11. How many pounds should be sown to the acre of (a) Kentucky blue- 

 grass, (h) timothy, (c) white clover, (d) redtop, (e) Canada bluegrass? 



12. Discuss the advantages of seeding to a mixture. 



13. How would you graze newly seeded land? 



14. Discuss the limitations of seeding to cultivated grasses on western 

 range lands generally, and show where such seeding may be expected to pay. 



15. Discuss the conditions under which artificial or hand seeding to native 

 forage plants may be justified.
