Araucaria Bidwillii - Queensland Araucaria

Araucaria Bidwillii, generally known as Queensland Araucaria, is located in the subtropical rainforests of Australia. These majestic trees have a long history of admiration and use by indigenous peoples as well as a fascination for botanists and nature lovers worldwide.

Taxonomy and phylogeny

Araucaria Bidwillii belongs to the Araucariaceae family and is closely related to other Araucaria species such as the Chilean Araucaria (Araucaria Araucana). Araucaria's genus is one of the oldest tree genres in the world and has a fascinating phylogenetic story that goes back to the time of the dinosaurs.

morphology

The Queensland Araucaria is an impressive evergreen tree that can reach heights of up to 30-45 meters. Its characteristic crown is pyramid -shaped with densely arranged, horizontal branches. The leaves are stiff, stiff and spirally arranged, and the bark is reddish-brown and scaly. The cones are strikingly large and heavy and can be up to 40 cm long and 15 kg.

ecology

Araucaria Bidwillii mainly thrives in subtropical rainforests, especially in the eastern coastal areas of Australia. These trees prefer moist, well -permeable soils and thrives at altitudes of 300 to 1,500 meters above sea level. They play an important role in the ecosystem by offering the living space and food for a variety of animals, including birds, small mammals and insects.

Cultural and economic importance

For indigenous Australian communities, in particular the Aborigines of the coastal areas, the Queensland Araucaria is of profound cultural importance. The cones of the tree, which are known as "Bunya nuts", were traditionally collected as an important source of food and used in ceremonies. Nowadays, Bunya nuts are still an estimated delicacy and are harvested and enjoyed by some communities in Queensland.

In addition, Araucaria Bidwillii also has economic importance, especially in forestry. The trees are estimated due to their robust wood for the construction of furniture, boats and other constructions. In some parts of the world, they are also grown as ornamental trees in parks and gardens, which leads to a certain degree of exotic and beauty in these environments.
