112 FARM FORESTRY 



insects and diseases. Such trees rarely make satisfactory 

 growth and they are also a menace to the trees around them, 

 because of the danger of the disease spreading. Trees that 

 have begun to decay or that are badly attacked by insects 

 should be immediately removed. 



Weed Trees. Every woodlot contains many species of 

 trees that are of little value or of no use on the farm. These 

 are called weed trees, such as dogwood, ironwood, blue beech, 

 bird cherry or any kind of tree that does not serve some use- 

 ful purpose. These trees occupy space in which more useful 

 kinds of trees might grow. 



Dead Trees. Dead trees and limbs and fallen trees should 

 be utilized for cordwood. Such material often serves as the 

 breeding place for insects that may attack living trees. Where 

 such material is utilized before it begins to decay it will make 

 satisfactory fuel wood. 



TREES THAT SHOULD NOT BE CUT, BUT SHOULD BE ALLOWED 

 TO REMAIN IN THE WOODLOT 



No tree should be removed unless there is some good reason 

 for cutting it or unless it is needed for a special purpose, and 

 no tree of less value will serve that purpose. 



In general, young, thriftily growing trees should not be 

 cut until mature. They are producing a high rate of interest 

 in the amount of wood laid on each year, and are increasing 

 rapidly in value. 



In the ordinary farm woodlot of irregular form no tree 

 should be removed unless there are smaller trees beneath it to 

 grow up and occupy its place or unless some provision is made 

 for starting new trees. Many woodlots have large holes in 

 the canopy where trees were removed many years before. 

 Grass forming under the openings prevents young trees from 

 starting. Such openings should be planted with trees.
