HABITAT TYPES AND PLANT COMMUNITIES : 
Smooth woodrush generally occurs with subalpine fir (Abies lasiocarpa)
and mountain hemlock (Tsuga mertensiana).  It also occupies 20 to 25
percent ground cover of subalpine larch (Larix lyallii) communities in
the Pacific Northwest [3].  Associated tree species include Douglas-fir
(Pseudotsuga menziesii), western larch (Larix occidentalis), western
white pine (Pinus monticola), lodgepole pine (P. contorta), whitebark
pine (P. albicaulis), and Engelmann spruce (Picea engelmannii).
Understory associates include grouse whortleberry (Vaccinum scoparium),
Sitka valerian (Valeriana sitchensis), mountain arnica (Arnica
latifolia), and menziesia (Menziesia ferruginea) [1,10,21,24,25].
