ABSABOKA DIVISION OF YELLOWSTONE FOREST RESERVE. 



Forest conditions. — The lower areas are covered with large and continuous 

 stands of lodgepole pine, with small admixtures of spruce and red fir. The stands 

 average 100 years old. The subalpine forest consists of white-bark pine, spruce, and 

 subalpine fir and is thin and scattering. 



Cutting. — None. 



Burns. — Along the east line small patches of burns, in the aggregate 500 acres, 

 extend into the township from the large burns in Hell Eoaring Basin. 



JRepro&uction. — Scanty, but sufficient to maintain the present density of stands. 

 The greater portion of the sapling and seedling growth is composed of lodgepole 

 pine. • 



Undergrowth. — Sparse. 



Litter. — There is a moderate amount of dead and down timber, killed by 

 overcrowding, in the lodgepole pine stands. In the subalpine forest the amount 

 of litter is small. 



Humus. — None.
