P. radiata was introduced to Australia in the 1870s. It is the dominant tree species in the Australian plantation estate - so much so that many Australians are concerned by the resulting loss of native wildlife habitat. The species is widely regarded as an environmental weed across southeastern and southwestern Australia and the removal of individual plants beyond plantations is encouraged. In Sydney, there is a forest of introduced Monterey Pine trees in Prospect Hill, in the suburb of Pemulwuy.
