DISTRIBUTION AND OCCURRENCE
SPECIES: Pinus lambertiana | Sugar Pine 



GENERAL DISTRIBUTION : 
Sugar pine extends from the western slope of the Cascade Range in
north-central Oregon to the Sierra San Pedro Martir in Baja California.
Its distribution is almost continuous through the Klamath and Siskiyou
mountains and on western slopes of the Cascade Range and Sierra Nevada.
Smaller and more disjunct populations are found in the Coast Range of
southern Oregon and California, Transverse and Peninsula ranges of
southern California, and east of the Cascade and Sierra Nevada crests.
Its southern extremity is an isolated population high on a plateau in
the Sierra San Pedro Martir in Baja California, Mexico.  Over 80 percent
of its distribution is in California [16,21].

HABITAT TYPES AND PLANT COMMUNITIES : 
Sugar pine usually occurs in mixed-conifer forest stands with a wide
variety of overstory associates including ponderosa and Jeffrey pine
(Pinus ponderosa and P. jeffreyi), California red fir (Abies magnifica),
white fir (A. concolor), noble fir (A. procera), and Douglas-fir
(Pseudotsuga menziesii) [4,21].  In southern California, sugar pine is
characteristically found in vegetation types of the woodland and
timberland chaparral zones.  Canyon live oak (Quercus chrysolepis) is
found with sugar pine on more mesic sites, while at higher elevations
sugar pine occurs with mountain whitethorn (Ceanothus cordulatus), Parry
manzanita (Arctostaphylos parryana var. pinctorum), and bush chinkapin
(Castanopsis sempervirens) [14].
