A number of conifers originally introduced for forestry have become invasive species in parts of New Zealand, including radiata pine (Pinus radiata), lodgepole pine (P. contorta), Douglas fir (Pseudotsuga mensiezii) and European larch (Larix decidua).

In parts of South Africa, maritime pine (Pinus pinaster), patula pine (P. patula) and radiata pine have been declared invasive species.
These wilding conifers are a serious environmental issue causing problems for pastoral farming and for conservation.

Radiata pine 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.
