Around forests, plantations and shelter belts, sometimes spreading downwind for many kilometres into scrub and grassland.
In some inland parts of the South Id, e.g., the Amuri Range (N. Canterbury), Rakaia Valley (C. Canterbury), Mackenzie County (S. Canterbury), Corsican pine is aggressive and has invaded many hectares of scrub and grassland. The cones are very freely produced and often large quantities of viable seed are formed, even on fairly young trees. There are thousands of hectares of this sp. in state forests from N. Auckland to Southland, particularly in cooler areas such as the Rotorua-Taupo area and inland Canterbury. This subsp. has been known previously in N.Z. as P. nigra var. maritima and was first recorded as P. laricio.
