80 THE WOODLOT. 



FIGURE 26. 

 Diagram of Stand ix Berkshire County, Mass. 



Mixed forest of varying age, in which younger generations are abundantly repre- 

 sented under the dominant crop. Diameters, 6 to 24 inches; heights, 20 to 50 feet; 

 ages, 20 to 90 years. The shade-enduring species. Sugar Maple, Hemlock, and 

 Beech, have reproduced and thriven under the light-demanding species. White Birch 

 and Eed Maple. The result has been an approach to a selection forest which should 

 be cut so as to relieve and supplement the young crop. Of the dominant trees, Sugar 

 Maples 1 and 4, which are still thrifty and growing, are to be left. Then, when Red 

 Maple 1 and "White Birch 1, both overmature, are taken out, the younger stand 

 beneath, which has not suffered in their moderate shade, will be further replenished 

 with the seedlings of a very tolerant species, namely, Sugar Maple. Of the subor- 

 dinate trees only Sugar Maple 2, which has had both crowding and severe shading, 

 is to be cut. Red Maple 2, though of less tolerant species than the other young 

 trees, has been saved from suppression by the natural sparseness of the Birch crown 

 above it. These cuttings will make a beginning in the production of a selection 

 forest, as described on page 13.
