DISTRIBUTION AND OCCURRENCE
SPECIES: Cupressus bakeri | Baker Cypress 



GENERAL DISTRIBUTION : 
Baker cypress is restricted to northern California and southern Oregon.
Baker cypress (C. b. ssp. bakeri) occurs in Modoc, Plumas, Shasta, and
Siskiyou counties in California [18,25].  Siskiyou cypress (C. b. ssp.
matthewsii) has disjunct populations in the Siskiyou Mountains of
Josephine County, Oregon, and on Goosenest Mountain in Siskiyou County,
California [18,29]. The Bureau of Land Management administers the Baker
Cypress Natural Area and Timbered Crater Baker Cypress Natural Area,
both in Siskiyou and Modoc counties, California [16].

HABITAT TYPES AND PLANT COMMUNITIES : 
Baker cypress is a component of the northern interior cypress forest.
This habitat type is an open, fire-maintained, scrubby forest similar to
the knobcone pine (Pinus attenuata) forest.  It is associated with
serpentine chaparral, and intergrades on less severe sites with upper
Sonoran mixed chaparral, montane chaparral, or knobcone pine forest
community types.  On more mesic sites, the northern interior cypress
forest intergrades with mixed evergreen forest or montane coniferous
forest [11].  Baker cypress rarely forms pure stands [31].  The Timbered
Crater grove is associated with yellow pine (Pinus ponderosa and P.
jeffreyi) forest and suggests a transition zone between several plant
communities, including northern juniper woodland, yellow pine forest,
and sagebrush scrub.  High elevation groves of Baker cypress in Plumas
County, California, are associated with red fir (Abies magnifica)
forest [29].
