A scarred tree or scar tree, also known as a canoe tree and shield tree, is a tree which has had bark removed by Aboriginal Australians for the creation of bark canoes, shelters, weapons such as shields, tools, traps, containers (such as coolamons), or other artefacts. Carved trees may also be created as a form of artistic and spiritual expression by some Aboriginal peoples, to mark sites of significance such as burial sites. Trees in some areas are culturally modified in other ways that change their form, including "trees-in-trees".
Description
Bark was removed by making deep cuts in a tree with a stone pickaxe or other similar tool. The area of bark removed is typically regular in shape, often with parallel sides and slightly pointed or rounded ends, and the scar usually stops above ground level. Australian native Eucalypt species such as box and red gum (especially in Victoria), swamp mahogany, river box, or whichever species are native in the area. Scars remain in trees that are often over 200 years old. Sometimes there is exposed sapwood at the base or at the top of the scar, showing axe cuts. Aboriginal people removed bark from trees to make things like canoes, axes, tools, containers and shields, as well as to build temporary shelters. Sometimes they cut toe holds for ease of climbing, with the trees used as lookouts or to hunt for bush foods. Wrapping meat or seafood in layers of moistened paperbark (Melaleuca) and nestling it into the hot coals is one of traditional aboriginal way of cooking. Bark canoes were mainly used for fishing or crossing rivers or lakes rather than long journeys. They were usually propelled by punting with a long stick. To remove bark, the Aboriginal people cut an outline of the shape they wanted using stone axes or, once Europeans had arrived, steel axes. The bark was then levered off. Sometimes the axe marks made by Aboriginal people are still visible on the sapwood of the tree, but usually the marks will be hidden because the bark has grown back. The amount of bark regrowth may help you tell the age of the scar. Sometimes, if the scar is very old, it will be completely covered by regrowth
Bark canoes
Aboriginal people made several kinds of bark canoes. Bark canoes were made from the bark of certain trees, notably red gum, stringybark, swamp mahogany and river box and were made during summer. Bark canoes were made from massive single piece of bark. They were softened over fire, tied at both ends to make a canoe shape and used sticks or spars to keep it open. The resin from Xanthorrhoea (grass tree) was used to waterproof the base and were also used to repair any leaks or small holes. This bark canoe is called Nawi. A small fire was kept alight in the bark canoe on a bed of wet clay or seaweed. This kept people warm in the winter and also allowed them to cook the fish they had caught. Yuki is another form of bark canoe, the bark on the tree was cut-out in a shape of a canoe, it was then propped up all round the edge with the help of sticks and weighted in the middle with stones and logs of wood, then a fire is made inside and under the bark to heat the sap and make it pliable and soft. It is then left to dry in the canoe shape. Bark strips could also be sewn together to make larger canoes, known as Gumung derrka and Na-riyarrku or sewn bark canoes. Non-Indigenous Australians called the trees thus marked as scarred trees, scar trees, canoe trees or shield trees. In the 17th century, dugout canoe technology appeared in northern Australia coastline, to supplement the bark canoe, causing many changes to both the hunting practices and the society of the northern coastline Aboriginal peoples.
Carved trees Carved trees are known across Australia in various forms. Most remarkable example of carved trees are found in New South Wales, and are the work specifically of Gamilaroi and Wiradjuri peoples. They were created to mark sites of particular ceremonial significance, such as initiation or burial sites. They are also known as arborglyphs, dendroglyphs and teleteglyphs. In Western Australia, a form of tree carving also occurred in the southwest where trees near the burial sites were sometimes carved. Notches and figures daubed red are known for the Harvey River area. Circles and other carved ornamentations are reported for Perth, circles for the 'Southwest. Notches are cut on two trees for each grave, an even number of notches for a man, an uneven for a woman, by the tribes from Esperance. In Northwest, trees were carved with figures of emu and kangaroo but an overwhelming majority of the engravings were of snakes, some of which undulated across the tree while others coiled onto themselves. In Queensland, carved trees with zoomorphs and anthropomorphs in a form of snakes, lizards and humans are known. Many carved trees were destroyed by land clearing, bush fires, farming and natural decay. During the 19th century, sections of these carved trees from New South Wales were removed and placed in museums, but there is now a move not only to return these trees to the land of origin, but also to revive the practice of carved trees.
Other culturally modified trees In inland northern New South Wales and over the border into Queensland, around 1000 culturally modified trees have been recorded. The term is used to describe trees modified in some way by local Indigenous people, including trees planted within trees ("trees-in-trees"), trees that have been shaped into rings or arrows, or cut out to make bowls to hold water. A group of people including academics and local Indigenous and non-Indigenous people are working to improve knowledge about modified trees, and to bring about both scientific and legislative recognition and protection of trees-in-trees.
