but which were obviously difficult to traverse because of rocky substrate. 

 If an area could not be defined as one of the rocky terrains, then it 

 was classified as one of the four remaining terrain types, including: 

 ridge , the line of land separating two drainages; floodplain , the low- 

 lying, flat or gently sloping land adjacent to a water course; par^i' a 

 nontimbered flat or sloping area; sidehill , a catchall term used to 

 categorize any nonrocky area which would not fit any of the other 

 terrain types. The cliff, talus and park types by definition are not 

 timbered, but the five remaining terrain types could support any cover 

 type. A map of terrain types is shown in Figure 3. 



The area south of the river in the vicinity of Kootenai Falls is 

 heavily timbered and falls within the relatively moist western red 

 cedar/ queencup beadlily and western hemlock/queencup beadlily habitat 

 types, while the area to the north falls primarily within the much drier 

 Douglas fir/ninebark, Douglas f ir/bluebunch wheatgrass and Douglas 

 fir/snowberry habitat types. Rocky outcrops, grassy meadows, and scree 

 slopes are much more prevalent north of the river. 



HABITAT CATEGORIES 



Habitat categories were defined based on the above classification 

 and on the 1:1200 vegetation map prepared as part of the vegetation 

 study (Olson-Elliott & Associates 1979). Table 1 lists the habitat 

 categories used in this study, their abbreviations, their component 

 vegetation community types, and dominant vegetation. More detailed 

 descriptions of the vegetation types and a map showing their distri- 

 bution in the study area has been presented in the vegetation report 

 (Olson-Elliott & Associates 1979).
