Weed Potential
As a weedRadiata Pine is invasive in a range of regions appearing in habitats that include dry or moist woodlands, forests and occasionally heathlands. It also occurs in disturbed soils or along bushland margins.
There are up to 8-Pinus species that are regarded as weeds but Radiata Pine is the more commonly found plant due to its extensive cultivation.
They are tolerant of cold winter temperatures and hot dry summers and exposed positions and can grow in most well drained sandy-stony to clay soils.
Trees produce seeds with in 8 to 15 -years and can live for 100 years. Pines reduce light and form a thick layer of needles on the ground inhibiting the regeneration of native tree or shrub seedlings and understorey plants. Trees also reduce the fertility of soil and interfere with the nutrient and the water cycle. Cones may persist on mature plants for several seasons and the seeds are dispersed by wind or by birds (Yellow Tailed Black Cockatoos).
Controlmethods include physically digging out seedlings and small plants when the soil is moist ensuring that the roots are removed as the slender trunks snap off easily and the plant re-shoots from the base.
Fruiting branches should be bagged and destroyed. Plants can be cut and painted on the stems with the sap wood revealed or drilled and injected in the trunk towards the base with a non-selective herbicide.
Large trees can be ring barked or cut down and the stump painted with a non-selective herbicide. Young plants or seedlings may be sprayed with a non-selective herbicide during spring while the plant is actively growing.
