HABITAT TYPES AND PLANT COMMUNITIES : 
Slender hairgrass occurs in a wide variety of habitats including maple
(Acer spp.), aspen (Populus spp.), fir-spruce (Abies-Picea spp.),
ponderosa pine (Pinus ponderosa), and lodgepole pine (P. contorta).  It
also occurs in alpine, subalpine forest, riparian forest, meadow, and
coastal prairie communities [13,17,24,30,35].

Slender hairgrass is an indicator species in lodgepole pine and
Douglas-fir (Pseudotsuga menziesii) forests of western Oregon [12].  

Slender hairgrass occurs in many wetland and riparian habitats.  In
Nevada, slender hairgrass is a component of the willow (Salix spp.)-forb
community type of the subalpine zone.  In northeastern California,
slender hairgrass occurs in the quaking aspen/skunkcabbage (Populus
tremuloides/Veratrum californicum) habitat type [30].  Slender hairgrass
occurs in the montane black cottonwood (P. trichocarpa) riparian forest
of California.  This is a dense, mixed riparian forest dominated by
black cottonwood with emergent Jeffrey pine (Pinus jeffreyi) towering up
to 150 feet (45 m) [17].

Slender hairgrass occurs in moist forests.  It is a member of the
lodgepole pine/California oatgrass (Danthonia californica) community on
moist sites in Washington and Oregon [5].  In the Cascade Ranges of
southern Oregon, slender hairgrass occurs in the western hemlock/Pacific
rhododendron-twinflower (Tsuga heterophylla/Rhododendron
macrophyllum-Linnaea borealis var. longiflora) association [1].  In
eastern Washingtion and northern Idaho, slender hairgrass occurs in
western redcedar (Thuja plicata) forests [3].  In larch-fir (Larix-Abies
spp.) forests of Montana, slender hairgrass occurs in two phases:  the
subalpine fir/queencup beadlily-rusty menziesia (A.
lasiocarpa/Clintonia uniflora-Menziesia ferruginea) phase and the
subalpine fir/queencup beadlily-beargrass (A. lasiocarpa/C.
uniflora-Xerophyllum tenax) phase [32].

Slender hairgrass also occurs in moderate to dry habitats.  In eastern
Washington and northern Idaho, slender hairgrass is a common understory
species in subalpine fir, grand fir (A. grandis), Douglas-fir, and
ponderosa pine forests [3].  In the Santa Lucia and Diablo ranges of
southern California, slender hairgrass can be found in the understory of
sugar pine (P. lambertiana), bristlecone fir (Abies bracteata), and
mixed oak-Coulter pine (Quercus spp.-Pinus coulteri) communities [10].
In the Sierra Nevada, slender hairgrass occurs in Jeffrey pine forests
[31].  Slender hairgrass has been a member of the fescue-oatgrass
(Festuca-Danthonia spp.) coastal prairie community along the coast of
California [13].  Slender hairgrass is a component of the subalpine forb
community in the Bridger-Teton National Forest of Wyoming [9].

Species not previously mentioned but commonly associated with slender
hairgrass include incense-cedar (Libocedrus decurrens), Rocky Mountain
maple (Acer glabrum), Pacific yew (Taxus brevifolia), erect willow
(Salix rigida), western chokecherry (Prunus virginiana var. demissa),
Oregon boxwood (Pachistima myrsinites), devil's club (Oplopanax
horridus), ninebark (Physocarpus malvaceus), oceanspray (Holodiscus
discolor), Wood's rose (Rosa woodsii), starry Solomon-seal (Smilacina
stellata), longstalk clover (Trifolium longpipes), salal (Gaultheria
shallon), Oregon-grape (Berberis nervosa), larkspur (Delphinium
nutallianum), western yarrow (Achillea millefolium), sweetscented
bedstraw (Galium triflorum), tufted hairgrass (Deschampsia cespitosa),
red fescue (Festuca rubra), western needlegrass (Stipa occidentalis),
blue wildrye (Elymus glaucus), prairie junegrass (Koeleria macrantha),
Columbia brome (Bromus vulgaris), Merten's rush (Juncus mertensianus),
and sedge (Carex spp.) [3,5,17,24,30].
