Abandoned Farmstead (AF) . The A.F. h.c. is similar to the OF h.c. but is 

 presently unoccupied by humans. 



Badlands Series 



Badlands Comples (BA) . Corresponding to the Big Sagebrush Scabland c.t., 

 the BA h.c. is actually a complex mosaic of many types associated with deeply 

 eroded shale and mudstone badlands and the resultant highly variable topography. 

 Bare earth and weathered shale and mudstone devoid of vegetation generally pre- 

 dominate, but patches of big and silver sagebrush, grassland, little bluestem, 

 tall coulee shrubbery, and, in drainage bottoms, various wetland types are inter- 

 spersed in a manner not readily mapped at the scale used in the vegetation base- 

 line study. 



Bare Earth (BE) . The BE h.c. consists of bare soil (rather than rock) 

 having less than ten percent canopy coverage of vegetation. 



Scoria (SC) . The SC h.c. includes all scoria outcrops having less than 

 ten percent canopy coverage of vegetation.
