2020. Paraná Pine (Araucaria angustifolia): The most planted native forest tree species in Argentina. Chap. 15. pp. 395-426. In: Low Intensity Breeding of Native Forest Trees in Argentina.

Natural distribution in Argentina: the western extreme of a large area.Araucaria angustifolia (Bertol.) Kuntze (Paraná pine) is one of the few native South American conifers, and belongs to the order Pinales, Araucariaceae family. This family dominated both hemispheres during most part of the Mesozoic Era and the beginning of the Cenozoic until the appearance of Angiosperms, which eventually prevailed. The genus Araucaria is present in southern hemisphere, but their fossils have been registered throughout the world (Kranitz et al. 2014). A. araucana and A. angustifolia are the only living species representative of the genus in South America.Although several authors early established the natural range of A. angustifolia (Cavalcanti 1908, Ruhle 1928 and James 1942, cited by Moura 1975), Hueck (1952) was the one who made the most detailed description, providing accurate data of the presence of the species between 18° and 30° S and between 41° and 54° 30´ W. The geographical distribution of A. angustifolia (Fig. 1) includes a main continuous area in the eastern and central plateau of Southern Brazil (states of Rio Grande do Sul and Santa Catarina), and marginal forests that extend with a more dispersed pattern within the extreme northeast of Argentina (Fig. 2), eastern Paraguay and the State of Paraná (Brazil). Also, some sparse populations spread northward till the State of Rio de Janeiro (Di Bitetti et al. 2003, Sebbenn et al. 2003). The discontinued presence of A. angustifolia in its natural distribution area is usually associated with altitude. It usually finds its lowest boundaries between 500 and 600 m asl, climbing up to 1,200 m asl in the Serra da Matiqueira and the Itatiaia, and even up to 1800 m asl in the Campos do Jordão region, at the north of its range. A. angustifolia forests are phytogeographycally classified as a District within the Paranaense biogeographic Province of the Amazonian Dominion (Cabrera and Willink 1980), but are more generally included within the Alto Paraná Rainforest.
