tual spacing of natural-grown trees is uneven. If a 

 reserved tree lias no neighbor of crop-tree description 

 within the "D + 6" distance on one side, such a tree may 

 be left at less distance than that from it on the op- 

 posite side. Thinning to correct spacing of trees in a 

 farm woodland needs to be done about once in 5 years. 

 3. Correct understocking by planting trees, unless 

 it is being or can be corrected at a satisfactory rate by 

 growth and reproduction of trees already present. If 

 the "D + 6" spacing rule is followed, in many instances 

 understocking will eventually be corrected in this way. 

 Openings in the woodland usually signify that natural 

 reproduction is being prevented by fire or by livestock. 

 In such a situation the corrective is not to plant trees but 

 to control fire and livestock. 



HARVESTING BY PLAN 



The farm woodland should be so managed that it 

 will make a regular, planned contribution to the 

 farmer's income. Frequent light cutting is best for 



wood production and soil protection, and usually is in 



Woodland management and pasture management cannot be 

 practiced successfuUy on the same area at the same time.
