radiata (Monterey Pine) is a North American tree that has been
widely planted in forestry plantations and has become naturalised in
many parts of Tasmania.
It is an erect tree with spreading
branches and very distinctive foliage. The leaves are long needles
(7-14 cm long) and are held in clusters of three with a brown sheath
around the base. The female cones are large and woody.
Pinus pinaster and P.
wallichiana have also been naturalised in Tasmania. They have
either two (P. pinaster) or five (P. wallichiana)
leaves per fascicle. P. wallichiana has very elongate cones.
