Pinus radiata (weed) D. Don - (Monterey pine)
This pine tree is native to California (USA), but has been planted as a source of timber in many other countries, including in the southern hemisphere. It is shade–intolerant and can therefore easily establish under the forest canopy. This trait makes P. radiata highly invasive outside its native range. Invasive populations disrupt the ecology of an area, leading, for example, to a reduction in the biodiversity (Gómez et al., 2019).
In South America, P. radiata is one of several exotic species of pine trees which are commonly planted and can escape from forest plantations. In Argentina for example, invasive P. radiata pines have reduced the pollination and seed production of the native Andean cedar (Austrocedrus chilensis) by altering the dynamics of wind-borne pollen flow among the trees (Martyniuk et al., 2015).
