CHABACTEE AND VOLUME OF MERCHANTABLE TiSlBEE. 25 



from 500 to 900 cabic feet for the thinnest and most scattered subalpine stands to 

 3,000 and 4,000 cubic feet for the closely stocked, middle-aged lodgepole-pine forest. 

 In some of the very heavily stocked areas in Slough Creek and Hell Roaring Creek 

 basins the amount rises to 10,000 cubic feet per acre. With the exception of Slough 

 Creek and Hell Roaring Creek basins little of the area carries fully stocked stands. 

 Notwithstanding rocky and comparatively barren soil, the region will be capable of 

 sustaining at least twice the volume of timber it now does, if fires are totally 

 suppressed, grazing and cutting restricted, and sheeping absolutely prohibited. 



The total volume of mill timber in the Absaroka division, estimated on the 

 minimum basis of 8 inches in diameter, breast high, and 10 feet of available bole, 

 with the proportions furnished by each species, is as follows:

Feet B. M. 



Limber pine 1,000,000 



. Lodgepole pine 434,000,000 



Yellow pine : 980,000 



White pine 3,550,000 



White-bark pine 8,000,000 



Eedfir 147,950,000 



Subalpine fir ._ 1,000,000 



Engelmann spruce 376,200,000 



Total 972,680,000 



This gives an average stand slightly in excess of 2,190 feet B. M., per for- 

 ested acre. 



The volume of pole and fuel timber in the Absaroka division of the reserve, 

 including the woodlands, is as follows, basing the estimates on diameters not less 

 than 4 inches, breast high:

Limber pine - 11,235,000 



Lodgepole pine -• 511,900,000 



Yellow pine 1,440,000 



White pine 300,000 



White-bark pine 82,230,000 



Eedfir 76,200,000 



Subalpine fir 112,050,000 



Engelmann spruce 155, 100, 000 



Aspen and cotton wood -. 2, 100, 000 



Total 952,555,000 



The average volume of pole and fuel timber is nearly 2,000 cubic feet per acre. 

 Counting 180 cubic feet of timber equal to 1,000 feet B. M., the average stand is 

 raised to 2,390 cubic feet per timbered acre.
