The Calocedrus Decurrens
is commonly known as Incense-cedar
, < Go Back
Incense-cedar is generally found from the southern slope of Mount Hood,
Oregon, southward through the Siskiyou, Klamath, and Warner mountains,
Cascade and Coast ranges, and from the Sierra Nevada to the Hanson
Laguna and Sierra de San Pedro Martir ranges in Baja, California.
Incense-cedar is most common in the Sierra Nevada, occurring
individually or in small groups [19
]. It is cultivated in Hawaii [30
The currently accepted scientific name for incense-cedar is Calocedrus
decurrens (Torrey) Florin. There are no infrataxa [28
On dry, shady sites, incense-cedar is considered climax due in part to
its relative tolerance of shade. In the northern Oregon Cascades,
however, incense-cedar typically grows as a minor component of stands
dominated by western hemlock (Tsuga heterophylla), western redcedar (Thuja
plicata), and grand fir (Abies grandis) .
Typically, incense-cedar is found in mixed-forest types and rarely in
pure stands. Overstory associates found throughout its range include
white fir (Abies concolor), ponderosa pine (Pinus ponderosa), Jeffrey
pine (P. jeffreyi), sugar pine (P. lambertiana), and California black
oak (Quercus kelloggii) .
