The Bigcone Douglas-fir (Pseudotsuga macrocarpa) is an evergreen conifer native to the mountains of southern California, occurring from the San Rafael Mountains in central Santa Barbara County and the southwest of the Tehachapi Mountains of southwestern Kern County, south to Julian in San Diego County. It is notable for having the largest (by far) cones in its genus, hence the name. Bigcone Douglas-fir typically grows from 15-30 meter (50-100 feet) in height and 0.5-1.5 meter (2-5 feet) in trunk diameter. The growth form is straight, with a conical crown from 12-30 meter (40-100 feet) broad, and a strong and spreading root system. The bark is deeply ridged, composed of thin, woodlike plates separating heavy layers of cork; bark of trees over 1 meter (3 feet) in diameter is from 15-20 centimeter (6-8 inches) thick. The main branches are long and spreading with pendulous side shoots.
