|Botanical Name||Pinus spp.|
|Origin||Mostly temperate regions, some subtropical, tropical.|
DescriptionEvergreen, resinous tree or, less commonly, shrub. Regular whorled branches, rough bark with fissures. Needle-like leaves in bunches. Produces cones.
Where is it found?Shrub, open places i.e. open slopes. Near pine plantations.
Why is it a problem?Dominates/excludes other vegetation. Seeds into shrubland areas, and older trees become a canopy component in forest. Maritime pine (Pinus pinaster) is an aggressive species tolerating hard conditions. Lodgepole pine (P.contorta) is a serious problem in the southern part of the Bay of Plenty Region.
How does it spread?Seeds from shelter belts and plantations. Planted in parks and cemeteries. Often regenerates prolifically after fire.
How do I get rid of it?
Young plants may be hand pulled or grubbed out. Fell larger trees.
An alternative to felling tree. With 20 mm timber auger make holes 80 mm deep, three to five for each tree depending on size. Fill with undiluted Glyphosate or 5 g Metsulfuron / litre of water. Results should be obvious within 5-10 days.
Hand pull seedlings. Fell or drill and treat larger trees.
In coastal areas rotting stumps are often a good seed bed for pohutukawa.
