HABITAT TYPES AND PLANT COMMUNITIES : 
Summer-cypress occurs mainly in grassland, mixed-grass prairie,
shortgrass prairie, sagebrush, and desert shrub communities of western
North America.

Summer-cypress is common in floodplain and riparian habitats.  


In Quebec summer-cypress is codominant with mayweed (Matricaria
maritima) along disturbed riverbanks [63].  In eastern Montana and
Wyoming summer-cypress occurs on meadow floodplains and temporary
mudflats [50].  It has been noted in Utah in marshes dominated by
bulrushes (Scirpus spp.) and cattails (Typha spp.).  Upland associates
include black greasewood (Sarcobatus vermiculatus), Europe swampfire
(Salicornia europaea), and smotherweed (Bassia hyssopifolia) [66,96].
It also occurs with saltcedar (Tamarix ramosissima) [15].  On the
Colorado-Kansas border, summer-cypress occurs on the Arkansas River
floodplain.  Common associates include saltcedar, sand dropseed
(Sporobolus cryptandrus), saltgrass (Distichlis spicata), and western
wheatgrass (Pascopyrum smithii) [57].  In New Mexico summer-cypress
forms a dense cover along creek floodplains.  Associates in the adjacent
grassland include cholla cactus (Opuntia imbricata), blue grama
(Bouteloua gracilis), sideoats grama (B. curtipendula), hairy grama (B.
hirsuta), and muhly (Muhlenbergia spp.)  [68].

Prairie and plains grassland associates not previosly listed include red
threeawn (Aristida purpurea) and plains silver sagebrush (Artemisia cana
ssp. cana) in South Dakota [19].  In Kansas summer-cypress occurs in
mixed-grass prairie with sunflower (Helianthus annuus), switchgrass
(Panicum virgatum), ragweed (Ambrosia psilostachya), western poison-ivy
(Toxicodendron rydbergii), and lambsquarter (Chenopodium album) [29,42].
Summer-cypress occurs also occurs in the Great Plains with saltgrass,
foxtail barley (Critestion jubatum), and alkali sacaton (Sporobolus
airoides) [91].  In Colorado summer-cypress occurs in shortgrass prairie
dominated by indiangrass (Sorghastrum nutans) [10].  In Texas
summer-cypress occurs in the Southern High Plains [84].

Summer-cypress occurs in desert shrub communities of Utah, Montana, and
Wyoming [25,50].  In Utah summer-cypress occurs in shadscale (Atriplex
confertifolia) [25], in saline meadows dominated by saltgrass and annual
weeds, and in saltgrass-alkaligrass (Puccinellia spp.) communities [14].
In Montana and Wyoming summer-cypress occurs in saltbush (Atriplex spp.)
desert shrubland and greasewood (Sarcobatus spp.) desert shrubland
communities [50].  Common associates include Gardner's saltbush (A.
gardneri), budsage (Artemisia spinescens), indiangrass, and plains
prickly pear (Opuntia polyacantha) [50].
