Fig. 4.2. (above) Mid-elevation riparian shrublands on Jack
creek in the Sierra Madre. common shrubs and trees include
Geyer's willow, Booth's willow, diamondleaf willow, alder,
shrubby cinquefoil, engelmann spruce, subalpine fir, and
lodgepole pine. Herbaceous plants include elephanthead
lousewort, red and yellow indian paintbrush, and various wet-
land sedges. the upland forests are dominated by lodgepole
pine and aspen at lower elevations and engelmann spruce
and subalpine fir at higher elevations. Mountain big sage-
brush, idaho fescue, lupine, and desert indian paintbrush are
common on the drier, south-facing slope in the foreground.
elevation 8,500 feet. See also fig. 2.5.
Fig. 4.3. (left) Bebb and Geyer's willow occur along creeks
in the foothills, forming a riparian greenbelt in otherwise
semi-arid landscapes, such as here along Little Sage creek on
the north end of the Sierra Madre. Riparian zones often are
subject to heavy grazing and browsing by large herbivores,
causing some shrubs to have a pruned appearance. Shrub-
lands dominated by Wyoming big sagebrush occur on the
upland. elevation 7,500 feet.
