Extreme resistant thinning. All oaks removed and forest cover seriously broken. 

 Natural pine reproduction is expected, which will be followed by the removal 

 of remaining large trees. Notice the hewed oak ties. 



Moderate thinning. All possible nonresistant trees removed, but forest cover not 

 seriously broken. Wood enough cut to pay for the cost of the work. First 

 stage of remaking the stand into a resistant growth if thinning is followed by 

 natural reproduction or by planting of pine.
