HABITAT TYPES AND PLANT COMMUNITIES : 
Sweet grass usually grows among other grasses or shrubs; it is seldom
found in pure stands [5].

Sweet grass occurs in north-central Alberta in the wheatgrass (Agropyron
spp., sensu latu)-sedge (Carex spp.) community in low, moist areas.
Associated species include slender wheatgrass (Elymus trachycaulus),
slough sedge (Carex atherodes), false-melic (Schizachne purpurascens),
brome (Bromus spp.), reed grass (Calamagrostis spp.), meadow sedge
(Carex praticola), and American vetch (Vicia americana).  This community
is within the wheatgrass-needlegrass (Stipa spp.) association [23].

Associates of sweet grass in the meadow stage of succession on glacial
gravel outwash terraces in south-central Alaska include boreal wildrye
(Leymus innovatus), altai fescue (Festuca altaica), bluegrass (Poa
spp.), Sierra larkspur (Delphinium glaucum), monkshood (Aconitum
delphinifolium), and northern goldenrod (Solidago multiradiata).  A
nearly continuous moss mat, primarily of mountain fern moss (Hylocomium
splendens), grows under this vegetation [32].

Associates of sweet grass in a meadow on the banks of the Churchill
River on the Hudson Bay Lowlands in northeastern Manitoba include red
fescue (Festuca rubra), alkali grass (Puccinellia paupercula), aster
(Aster puniceus var. firmus), bittercress (Cardamine pratensis), mud
sedge (Carex limosa), parnassia (Parnassia multiseta), lomatogonium
(Lomatogonium rotatum), and plantain (Plantago maritima).  Sweet grass
is one of the most important grasses of this community [26].
