Radiata Pine

	This large evergreen tree has been widely planted in Australia as a windbreak and timber tree. The Radiata Pine, from California, grows to 50 m high and is prevalent in high quality plantation areas. Winged seeds are contained in woody cones, from which they are released when ripe and easily spread by wind. This can result in widespread dispersal of this species into nearby vegetation.

HOW IT SPREADS It is possible that the cockatoos, who eat the seeds may sometimes carry the cones several kilometres and spread the seeds at great distance from mother plants. Self-sown young trees are a very common sight near mature trees. Other pine species may also be as invasive.

Please note: It is desirable to replace these pines with native conifers as exotic conifers do not harbour our native birds and small mammals.

	This hardy Western Australian native tree grows to about 15 m high. Male and female flowers are produced on separate trees. The male trees' rust-coloured foliage is evident in winter and spring. On female trees, distinctive cones are evident for most of the year. Thrives on most soil types including those of poor fertility.
