AB8AR0KA DIVISION OF fELEOWSTONB FOREST BESEEVE. 



£unis.— The region has been visited by severe and extensive fires, mostly 

 during 1882-83. The immediate valley of Boulder Eiver has suffered most severely, 

 and many of the fires have been clean burning, consuming everything. In the 

 aggregate, 7,600 acres have been burned over. 



Reproduction. — The restocking processes throughout the district are slow and 

 deficient. In the subalpine areas young growth is scanty. The burned-over tracts 

 are reforesting tardily, lodgepole pine at low and middle elevations everywhere 

 replacing the former stands of red fir. 



JJnd^growth. — The brush growth is scanty except here and there on the burned- 

 over tracts, where close growths of Oecmothus are occupying the ground and prevent- 

 ing reforestation. 



Litter. — In portions of the burned-over ground and in lodgepole-pine stands 75 

 to 90 years old are large accumulations of dead and fallen pole timber in various 

 stages of decay. 



Humus. — None.
