Taxonomic name: Pinus pinaster Soland., non Ait. Synonyms: Pinus maritima, Pinus mesogeneensid Common names: cluster pine (English), maritime pine (English) Organism type: tree Pinus pinaster, originally from the Mediterranean Basin, has been planted in temperate regions within and outside its natural range for a wide range of reasons. It regenerates readily almost everywhere it is planted and in many places it invades natural shrubland, forest and grassland. Pinus pinaster forms dense thickets which supress native plants, changes fire regimes and hydrological properties and alters habitats for many animals. Description An evergreen coniferous tree, growing 20-35m tall, with 2 needle-shaped leaves per fascicle (leaves usually 15-20cm long and stiff). Cones 10-22cm long. Occurs in: agricultural areas, coastland, natural forests, planted forests, range/grasslands, riparian zones, ruderal/disturbed, scrub/shrublands, urban areas General impacts This species regenerates profusely after fire, often resulting in dense thickets of plants close to killed adult plants. These dense thickets supress native plants, change fire regimes and hydrological properties and alter habitats for many animals. Local dispersal methods Forestry (local): On animals (local): Management information Physical: Mechanical control is currently the most effective way of dealing with invasive Pinus pinaster stands. All plants are felled and allowed to lie for 12-18 months. Reproduction Pinus pinaster reproduces exclusively from seeds (it does not sprout). The small, winged seeds are held in serotinous cones. Some seeds are released every year, especially during hot spells when cones open partially. Trees have thin bark and a poor re
