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 . Publications naming Gowen cypress as a community dominant are listed below.
