Fig. I. — Stump Patch. 12 Years After Cutting, With Bunchgrass 

 (Festuca arizonica) in the Background. 



Pine seedlings make rapid growth here in the absence of damage by grazing because of the large 

 amount of organic matter in the soil and the absence of living tree roots. Proper grazing is 

 necessary to hold herbaceous vegetation in check. 



Fig. 2. — Stump Patch on an Area Logged the Same Year as the One 

 Shown in Fig. I, but Protected Against all Grazing. 



The luxuriant vegetation often chokes out pine seedlings.
