Forest Types of the Coeur d'Alene Mountains 111 



type. These types are based entirely on the physical features of 

 the country and might be termed the management types, or those 

 types which, under proper forest management, it is hoped will 

 eventually represent the areas. 



There are also found two management types of less im- 

 portance, the yellow pine type and the alpine type. These cover 

 only a comparatively small area and do not produce timber of 

 so high a commercial value as is found in the white pine type. 



What has here been termed the western white pine type 

 might also be called the western hemlock-lowland fir type. And 

 possibly this is a more appropriate name as hemlock and fir are 

 the permanent or final type species. Western hemlock and low- 

 land fir grow equally well on the same site conditions as the 

 western white pine. Unless, then, the forest can be opened up in 

 some manner by fire or cutting, western hemlock and lowland 

 fir, by reason of their tolerance, will come in under heavy stands 

 of western white pine. 



The white pine type, although only a temporary one, has 

 been so named because it is the type sought after, white pine being 

 the most valuable timber in the region, and also because white pine 

 is the most widely distributed tree for the region as a whole. For 

 this locality, therefore, it is the great management type. 



These management types are quite distinct from the cover 

 types, which simply show as closely as possible the actual cover 

 or stand existing on the area at the present time. The cover type 

 is named from one, two or sometimes three of the leading 

 species on the area. It can readily be seen that for mixed stands 

 the problem of assigning a definite area to such a type is a diffi- 

 cult one. 



The western white pine type can be divided into the follow- 

 ing cover types, determined by the occurrence of western white 

 pine with other species. 



1. Western white pine type proper. 



2. Western hemlock western white pine type. 



3. Western hemlock red cedar western white pine type. 



4. Western white pine western larch type. 



5. Hemlock lowland fir type. 



The Douglas fir type can also be divided into two rough cover 

 types as follows : 



1. Douglas fir type proper. 



2. Douglas fir western larch type.
