HABITAT TYPES AND PLANT COMMUNITIES : 
Woolly panicum occurs in many habitat types and within diverse plant
communities.

On dry prairie ridges of central Wisconsin sand plains, associates of
woolly panicum include little bluestem (Schizachyrium scoparium),
skyblue aster (Aster oolentangiensis), heath aster (A. ericoides),
forked threeawn (Aristida basiramea), parasol sedge (Carex umbellata),
poverty oatgrass, prairie junegrass (Koeleria macrantha), tall
gayfeather (Liatris aspera), and Indiangrass (Sorghastrum nutans) [50].
In central and northwestern Wisconsin, woolly panicum is found on sandy
outwashes and former lake bottoms.  Associates include ragweed (Ambrosia

and Virginia tephrosia (Tephrosia virginiana) [46].

On the west slope of the Sierra Nevada in Placer County, California,
woolly panicum occurs in grazed meadows which follow natural drainages.
Associates include Thurber's bentgrass (Agrostis thurberiana), other
bentgrasses (Agrostis spp.), California oatgrass (Danthonia
californica), pullup muhly (Muhlenbergia filiformis), sedges (Carex
spp.), rushes (Juncus spp.), woodrushes (Luzula spp.), white clover
(Trifolium repens), seep monkeyflower (Mimulus guttatus), primrose
monkeyflower (M. primuloides), trailing St. Johnswort (Hypericum
anagalloides), and violets (Viola spp.) [1].

In the Adirondacks of New York, woolly panicum associates include
Pickering's reedgrass (Calamagrostis pickeringii), bluejoint reedgrass
(C. canadensis), northern reedgrass (C. stricta ssp. inexpansa), sedges,
poverty oatgrass (Danthonia spicata), threeway sedge (Dulichium
