Key Plant Community Associations
Gowen cypress can occur in dense thickets as well as in open groves.
Dense thickets are common in regenerating burns . In Monterey
County, Gowen cypress (Cupressus goveniana ssp. goveniana) and bishop
pine (P. muricata) form almost impenetrable thickets . In some
areas Gowen cypress is associated with closed-cone coniferous woodlands
and closed-cone pine-cypress forests [5,24,26].
Mendocino cypress is associated with redwood (Sequoia
sempervirens)-Douglas-fir (Pseudotsuga menziesii) and other north coast
coniferous forests in Mendocino County . This subspecies is also a
component of the Mendocino pygmy cypress forest, which intergrades with
upland redwood and Sitka spruce (Picea sitchensis)-grand fir (Abies
grandis) forests .
Gowen cypress (C. g. ssp. goveniana) is a component of the Monterey
pygmy cypress forest, which intergrades with Monterey pine (Pinus
radiata) forest on deep soils .
