FOREST PLANTING IN THE INTERMOUNTAIN REGION.

the large heavy top. The use of this class of stock for field planting 

 is out of the question. If the first two grades, or 10.5 per cent, are 

 considered for transplanting, the cost would prove excessive and the 

 resulting transplant stock of very questionable utility. 



The 1-2 stock shows up well in the transplant beds, but the root 

 development is discouragingly meager. The roots have very few 

 fibrous laterals and a dearth of root hairs. This stock does not show 

 up well for transplant stock when compared with 2-1 transplants. 

 There is the further disadvantage of transplanting 1-0 seedlings, 

 especially the Rocky Mountain form of western yellow pine, which 

 are too small to handle economically. The same objections hold for 

 1-1-1 stock. Furthermore, the second transplanting in the case of 

 1-1-1 and 2-1-1 stock does not have the same beneficial effect that 

 the first transplanting has in stimulating favorable root development. 

 The merits of the 2-1 class of stock are largely self-evident from the 

 foregoing discussion, especially when corroborated by the survival 

 data which follow. 



Field tests of the different classes of stock used commonly in this 

 district were made in three different localities. The essential results 

 are shown in Table 9.

1 Details of plantations are given for the areas as numbered in Table 9, as follows: 



1. Planted fall 1915 on sagebrush-ceanothus-oak brush-aspen area with a southern aspect, results shown 

 for fifth year after planting. 



2. Planted fall 1915 on ceanothus-oak brush area with a western aspect, results shown for fifth year after 

 planting. 



3. Planted spring 1916 on same area as preceding, results shown for fifth year after planting. 



4. Planted in spring of 1916 on burned-over sagebrush land, results shown for fourth year after planting. 



5. Planted spring of 1917 on same area as preceding, results shown for first year after planting, as all 

 age classes were dead at the next examination. 



6. Planted spring of 1917 on brushy northeast exposure coming back to bitterbrush (Kunzia tridentata) 

 and snowberry (Symphoricarpos sp.). 



7. Planted spring 1916 on open oak-brush site with western aspect. The plantation resulted ultimately 

 in total failure for all age classes. Results shown are for first year. 



8. Planted spring 1917 on oak-brush site with western aspect, more favorable than preceding. Results 

 shown for third year.
