The Cupressus Sargentii
is commonly known as Sargent Cypress
, < Go Back
Sargent cypress occurs only in California and has the widest
distribution of all of the coastal California cypress [20
scattered groves occur in the Coast Ranges from northern Mendocino
County south to Santa Barbara County [5
]. Sargent cypress is
cultivated in Hawaii [35
The currently accepted scientific name of Sargent cypress is Cupressus
sargentii Jeps. (Cupressaceae) [4
]. There are two recognized
Cupressus sargentii var. sargentii
Cupressus sargentii var. duttonii Jeps.
Natural hybridization between Sargent cypress and MacNab cypress
(Cupressus macnabiana) has been hypothesized, but evidence for it is
Sargent cypress is a component of the northern interior cypress forest.
This community is an open, fire-maintained, scrubby forest similar to
the knobcone pine (Pinus attenuata) forest. Sargent cypress occurs in
widely scattered, isolated groves throughout its range. It occurs in
dense thickets as well as in open groves and sparse stands . Dense
thickets are common in burned areas . Sargent cypress 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 [12,16]. Sargent cypress is associated with redwood
(Sequoia sempervirens)-Douglas-fir (Pseudotsuga menziesii) forest and
associated North Coast forests in Mendocino County, California [8,33].
It is commonly associated with chaparral and gray pine (Pinus sabiniana)
throughout its range [4,16,29]. In some areas, Sargent cypress is
associated with yellow pine (Pinus ponderosa and P. jeffreyi) forests,
closed-cone coniferous woodlands, and pine-cedar-cypress pygmy forests
[11,26,33]. Sargent cypress occurs sympatrically with MacNab cypress in
Lake County, California, where it is larger and tends to occupy lower
slopes than MacNab cypress [22,29].
