l^eforestation of Brush Fields 23 



age of stock in the various parts of the area planted. The data 

 gathered for 1-1 Yellow pine tabulated below shows, irrespective 

 of aspect, the per cent of living trees found in the different 

 densities of brush : 



Brush Density — Class Total Number Number Per Cent 



Count Alive Dead Alive 



Open brush 861 697 164 81 



Medium brush 890 698 192 78 



Dense brush 1106 688 418 62 



Total 2857 2083 774 73 



The conclusions to be drawn from the examination made and 

 the recommendations for future work of this kind will be dis- 

 cussed under the following heads : 



Soil — On a northern aspect the Yellow pines survived, regard- 

 less of whether they were on coarse, granitic soil, or on fine 

 humus loam. On the southern and southwestern aspects prac- 

 tically the only trees that survived on the coarse soil were in the 

 shade of the brush. The poorer the soil the more plants were 

 found in the shade of the brush ; and, in general, the less plants 

 were to be found on the poor aspects. Soil seems to intensify 

 the favorable or unfavorable effects of other factors. Where 

 Oiher factors are unfavorable, good soil becomes important in 

 direct proportion. 



Species — Nothing conclusive was shown in regard to the vari- 

 ous species planted. Sugar pine seemed to do about as well as 

 Yellow pine. There seems little room for doubt that the intoler- 

 ance of the pines was the principal cause for the greater per cent, 

 surviving in the open and medium brush, as against the dense 

 brush. For future work this should be taken into account: 

 openings and open brush should be planted with pines and the 

 dense brush with more tolerant species like firs and cedar. 



Age of Stock — Nothing conclusive was shown in regard to 

 age, as between the Yellow pine 1-1 and the 1-2. The data col- 

 lected show a smaller per cent, of 1-2 surviving than 1-1 under 

 practically the same conditions of aspect, brush, and soil. 



Density of Brush — The data collected show that as far as 

 Yellow pine 1-1 stock is concerned the more open the brush the 

 greater are the chances for success. Yellow pine was more 

 successful in the open, scattered brush than in the brush of 

 medium density, although this difference was not marked (only 

 3 per cent.). A greater difference was manifested between the 

 medium and the dense brush (16 per cent.) In future work,
