Protect the woodland from damage by fire and 

 browsing animals. 



Follow a time schedule for all woods work. Defi- 

 nitely plan cutting operations for each year, every other 

 j^ear, every fifth year, or whatever other interval seems 

 best. 



Organize the woodland on a map and on the ground 

 in accordance with the time schedule. If thinning is 

 needed only once in 5 years, the best plan may be to 

 divide the woodland into five parts and cut over one 

 part each year. 



Maintain full stands of timber with adequate space 

 for tree growth, following the D + 6 rule for spacing. 



Harvest the largest trees at the rate of one per 

 acre per year (including those used on the farm). 



Improve stand composition by always cutting the 

 poorest tree that will serve the purpose and by deaden- 

 ing trees that cannot be used even as fuel.
