Evergreen coniferous trees have such an unusual name, in a small number growing on the Australian continent. Most of them are on the territory of various reserves, since in the old days araucaria was practically destroyed.
Description of the species
The tree was named after the researcher from England John Bivilla. He first described it, and also sent several young trees to the English royal botanical garden. Thanks to this action, Araucaria Bivilla is now growing in Europe.
This species is characterized by a high height that reaches the height of the average 9-story building. The barrel can reach up to 125 centimeters in diameter, that is, it will not work to grab it with your hands. There are female specimens and male. Moreover, the first is larger.
The leaves have an oval-lanceolate type. They are prickly, quite hard and “leathery” in appearance and touch. The maximum sheet length is 7.5 centimeters, width is 1.5 centimeters. The location of the leaves differs depending on the height. So, on the side branches and young shoots, they grow on one side, and on the top of the crown spirally, as if wrapping around the branch.
Where it grows
Historical range of growth Australian continent. The largest number of trees is located in the eastern part of the state of Queensland and in the New South Wales. Araucaria is also along the coast of the mainland, which is part of subtropical forests.
This tree is noteworthy in that it is the only existing representative of the ancient Bunius section that is part of the Araucaria genus. Bunia was most widespread in the Mesozoic period, which ended 66 million years ago. The petrified remains of the trees included in the section were found in South America and Europe. Nowadays, the section is represented only by Araucaria Bivilla.
The use of man
This tree was widely used by people. Furniture was made from its strong wood, crafts and souvenirs made. Araucaria, as well as products from it, were sent to other continents. Industrial use required a large number of trunks, and the trees were cut “without looking back”. This attitude has led to a sharp reduction in the number of species. From the disappearance of Araucaria Biville, reserves and special protection measures saved.
