Cal-IPC 2006: Species Native to Part of California, but Invasive in Other Parts of the State

[Wikipedia] Range, Description: Hesperocyparis macrocarpa also known as Cupressus macrocarpa, or the Monterey cypress is a coniferous tree, and is one of several species of cypress trees endemic to California. The Monterey cypress is found naturally only on the Central Coast of California. Due to being a glacial relict, the natural distributional range of the species during modern times is confined to two small relict populations near Carmel, California, at Cypress Point in Pebble Beach and at Point Lobos.Historically during the peak of the last ice age, Monterey cypress would have likely comprised a much larger forest that extended much further north and south. Description Hesperocyparis macrocarpa is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 meters (133 feet) in perfect growing conditions, and its trunk diameter can reach 2.5 meters (over 8 feet). The foliage grows in dense sprays which are bright green in color and release a deep lemony aroma when crushed. The leaves are scale-like, 2-5 mm long, and produced on rounded (not flattened) shoots; seedlings up to a year old have needle-like leaves 4-8 mm long. The seed cones are globose to oblong, 20-40 mm long, with 6-14 scales, green at first, maturing brown about 20-24 months after pollination. The pollen cones are 3-5 mm long, and release their pollen in late winter or early spring. The Latin specific epithet macrocarpa means "with large fruit". (link added by Mary Ann Machi)
