xericShore pine grows in a maritime climate throughout most of its range.
Annual precipitation, which falls year-round and mostly in the form of
rain, is 60 to 200 inches (1,500-5,000 mm) [
15,
26]. Shore pine occurs
from sea level to the subalpine zone (5,030 feet [1,525 m]) in Alaska
[

Conditions are xeric in the southern-most part of shore pine's
distribution, where it occurs in closed-cone pine and cypress
communities of California [
48]. Shore pine habitat here includes
coastal dunes, seaside bluffs, and exposed rocky headlands; winds may be
strong and salty [
48]. Soils are Inceptisols, Alfisols, and Ultisols;
best growth is on well-drained loams with a pH of 5 [

26]. Here shore
pine occurs at elevations between sea level and 1,690 feet (0-507 m)
[

Overstory and understory tree species not mentioned in Distribution and
Occurrence include yellow-cedar (Chamaecyparis nootkatensis), Mendocino
White Plains lodgepole pine, bishop pine (Pinus muricata), and common
