Subspecies "Choristoneura lambertiana subretiniana" feeds on "Pinus contorta" and "Pinus jeffreyi". Jeffrey pine ("Pinus jeffreyi") is the dominant species at higher elevations. The Winter Garden included New Jersey's largest Jeffery pine ("Pinus jeffreyi"). "Pinus jeffreyi" is more stress tolerant than "Pinus ponderosa". As it mainly consists of n-heptane, "Pinus jeffreyi" resin is a poor source of turpentine. The overstory is composed of "Pinus jeffreyi", "Pseudotsuga menziesii", "Calocedrus decurrens", and "Arbutus menziesii". "Pinus jeffreyi" is closely related to "Pinus ponderosa" (ponderosa pine) and is similar in appearance.
