HABITAT TYPES AND PLANT COMMUNITIES : 
Sierra lodgepole pine is a dominant or codominant species in upper
montane and subalpine forests [8,33,43,48,57].  A poorly defined
lodgepole pine zone occurs above the red fir (Abies magnifica) zone and
below the subalpine forests of mountain hemlock (Tsuga mertensiana),
whitebark pine (Pinus albicaulis), and western white pine (P. monticola)
[48].  Sierra lodgepole pine forms extensive, pure stands in the Sierran
lodgepole pine zone [2,12,48].
