Tree invasions Melaleuca quinquinervia in Florida Willow (Salix Spp.) in Australasia Acacia and Eucalyptus species in South Africa and Europe Pines in the southern hemisphere (Richardson et al 1994)
Why study pines? Known age and extent of source populations Extensive source of seeds in plantations Plantations expose a range of vegetation communities Conspicuous in native eucalypt vegetation
