THE YIELD OF OTHER BROAD-LEAVED TREES 



THE following notes indicate approximately the 

 returns which will be yielded in the case of other 

 broad-leaved trees : 



Alder, up to the first 35 years, will yield about the 

 same volume of timber as Spanish Chestnut. 



Elm will yield about the same volume of timber as 

 Spanish Chestnut, but the thinnings at all ages 

 should be more severe. Hence the trees of the 

 final crop will have a larger girth than the more 

 densely grown Spanish Chestnut. 



Lime, up to the first 40 years, will yield about the 

 same volume of timber as Spanish Chestnut, and 

 will require to be thinned in the same manner. 



Red Oak (Q. rubra) will (?) yield about the same 

 volume of timber as Spanish Chestnut, but the 



thinnings during the first 30 years should be 

 rather more severe. 



Sycamore will yield a volume of timber about half-way 

 between that of Spanish Chestnut and Ash. On 

 Quality II. land, an average annual increment of 

 74 cub. ft. on a 60-year rotation should be 

 grown. Trees of the same height and girth 

 should, up to the first 30 years, be grown at 

 slightly greater distances apart than those 

 indicated for Spanish Chestnut, but after that 

 date the crop should be thinned so that the 

 distance apart of the trees more nearly approaches 

 that indicated in the case of Ash. 



Turkey Oak will yield rather a greater volume of 

 timber per acre than Ash ; trees having the same 

 height and girth should be thinned in a similar 

 manner.
