• <br /> APPENDIX III-H-2 <br /> VEGETATION TYPES IN DISTURBED AREAS <br /> AREA CHARACTERISTICS <br /> DISTURBED VEGETATION <br /> AREA TYPES * Characteristics given above <br /> 1 Spruce/Fir Parkland Spruce/Fir Parkland : The unit is variable in the <br /> composition of the understory . Conifer parklands <br /> typically consist of dense clumps or islands of <br /> Engelmann Spruce Picea engelmannii , Subalpine Fir <br /> Abies lassiocarpa , and Douglas-fir Pseudotsuga <br /> menziesi.i interspersed within open areas dominated <br /> by a large variety of shrubs and subshrubs , <br /> graminoids , and (orbs . <br /> In some areas , this community occurs on slopes <br /> too steep and unstable to support vegetation . These <br /> sites are marked by bare outcrops of sedimentary <br /> bedrock or by talus and scree -slopes . <br /> Aspen Woodland Aspen Woodland : The unit is dominated by a closed <br /> canopy (63 percent cover. ) of Quaking Aspen , with a <br /> predominantly herbaceous understory . The presence <br /> of scattered conifer seedlings suggests that this <br /> type is successional to coniferous forests , although <br /> apparently over long time periods . <br /> 2 Spruce/Fir Parkland <br /> 4 <br /> Aspen Woodland <br /> T <br /> 3 Spruce/Fir Parkland <br /> Aspen Woodland (nearby) <br /> 4 Spruce/Fir Parkland <br /> Aspen Woodland (nearby) <br />
