Pure stands of Pinus remorata regularly occur in more equable sites than those occupied by P. muricata. The fossil record suggests that this relationship has existed since at least the earliest Pleistocene. It apparently was the spread of drier, less equable, postglacial climate that opened new, intermediate coastal sites that favored hybrids of P. muricata × P. remorata , the latter a relict species closely allied to P. radiala var. cedrosensis.
