(Also known as Monterey Pine)
Type of weed: Woody weed
A very fast growing tree up to 50 m tall. The bark is thick and furrowed.
Leaves are linear, pine-like and arranged in groups of three; they are aromatic when crushed.
Male and female cones are produced on the same plant. Male cones are small and yellowish. Female cones are soft and purplish at first, ripening over 18–36 months to form 7–15 cm brown pine cones.
Radiata Pine has been widely planted for forestry and windbreaks. It is highly invasive usually in areas where the rainfall exceeds 600 mm. Seed is dispersed long distances by wind. The Yellow-Tailed Black Cockatoo uses the seed as a food source and spreads the seed further into bushland.
Impact on bushland
Pines reduce the fertility of soils, alter the nutrient and water cycles, reduce light levels and generate thick layers of pine needles that prevent seed regeneration and growth of seedlings. Radiata Pines form dense stands that shade or crowd out most native trees, eventually creating monocultures.
Radiata Pines attract other bird dispersed cool climate weeds such as Holly, prunus species, Privets, Ivy and Berberis.
Choose from local native plants such as:
- Hakea spp,
- Banksia spp,
- Petrophile spp.
- Isopogon spp,
- Mueller’s Cypress Pine (Callitris muelleri)
- She Oaks (Allocasuarina littoralis)
Council provides a tool, on its Mountain Landscapes website, to help you choose native alternative plantings. Choose your village, soil, vegetation community and the purpose of your planting, and the tool will give you suggestions.
- Drill and inject medium and small trees with herbicide.
- Cut off saplings at ground level (no herbicide required)
- Pull out seedlings.
Large trees (higher than 10 m) require a Tree Preservation Order (TPO) permit for removal.
