in northern Mexico [6].

PLANT COMMUNITIES :
Although timber is an important habitat component, grizzly bear prefer
more open habitats. Timbered plant communities most frequented by
grizzly bear include subalpine fir (Abies lasiocarpa)-whitebark pine
(Pinus albicaulis), lodgepole pine (P. contorta)-Douglas-fir
(Pseudotsuga menziesii), and spruce (Picea spp.)-western redcedar (Thuja
plicata)-hemlock (Tsuga spp.) forests. Sedge (Carex spp.)-bluegrass
(Poa spp.) meadows are also important, as well as shrubfields and lowand
high-elevation riparian communities [3,23,36,39].
