Pinus monticola (Western white pine) is a native California tree in the Pinaceae family, recognized by 5-needle bundles with short needle persistence and prickle-less hanging cones.
Western white pine is a California native conifer found in the Klamath Ranges, northern Coast Ranges, high Cascade Ranges, Sierra Nevada, and Great Basin in upper mixed-conifer to subalpine forests at elevations of 150 to 3,400 meters. Its mature trees develop distinctively narrow conic crowns with trunks up to 73 meters tall and bark that breaks into dark gray to red-brown square-like blocks. Growing with long blue-green needles arranged in bundles of five, each needle 3 to 10 centimeters long and appearing slightly glaucous and flexible. The tree produces large cylindrical seed cones 9 to 25 centimeters long, hanging pendulously and colored yellow-brown with thin scales and no visible prickles. Its unique bark texture and five-needled bundles make it a distinctive component of high-elevation western forest ecosystems.

How to tell it apart
vs Pseudotsuga: Pine needles come bundled in groups with papery sheaths; Douglas-fir needles attach individually to smooth twigs.; vs Abies: Pine needles come bundled in groups of 2-5; fir needles attach individually and directly to twigs.; vs Sequoia: Pine has bundled needles in groups of 2-5; redwood has individual scale-like or awl-shaped leaves on flat sprays.; vs Casuarina: Pine has true needles bundled in groups; Casuarina has jointed branchlets with whorls of tiny scale leaves.; vs Cedrus: Pine needles are bundled in tight clusters of 2-5; cedar needles grow in dense rosette-like clusters on short shoots.
