Big Cone Douglas Fir, Pino Alto
Found these on the side of a hill on the west side of the park.
neat little grove tucked away in this gully right by the 14 freeway. Not sure if they are still there as the area is getting hammered by an unnatural number of severe fires - probably due to mustard and bromus caused type conversion.
Silhouetted on the ridgetop and in the north facing gullies. This species extends the furthest into the chaparral of any chaparral conifer in California. Unlike the related Douglas-fir that grows to the north, this species is highly fire adapted, but is still threatened by changes in the fire regime.

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.
