Spread of exotic conifers on South Island rangelands.
G. G. Hunter and M. H. Douglas
A number of exotic conifers have spread from plantations into extensively grazed grasslands and scrublands in the South Island. Pinus contorta, Pinus nigra, Pinus radiata and Larix decidua are the species spreading most vigorously. Their spread, which pcses some questions about land use, is related to production and wind dispersal of seed, climatic conditions, vegetation cover and management.
Management options for wildling stands include wood production, prevention of seedling establishment by pasture management, and control of established wildlings by grazing, fire, and felling.
