of carved boab trees in Australia. In October 2022, the team published the results of their survey of such trees in the Tanami Desert. The survey records the dendroglyphs, which relate to the Lingka Dreaming track across the desert. Also known as the King Brown Snake dreaming, many of the carvings are of snakes, but also include emu and kangaroo tracks; geometric markings; and, further west, crocodiles, turtles and Wanjina figures. Chatham Islands In the Chatham Islands (Rēkohu) of New Zealand, the indigenous Moriori people practised the art of momori rakau, or tree carving. The carvings depict Moriori karapuna (ancestors) and symbols of the natural world, such as patiki (flounder) and the hopo (albatross). They are all done on the bark of Corynocarpus laevigatus, or kopi, trees, which have thick, soft bark, and are all located near evidence of settlements in the form of middens.They were done between sometime in the 17th century and around 1835, which is when the Māori people arrived on the island. Most of those seen today were made in the 19th century. During the 1940s, many fallen trees were found with carvings, in 31 different places on Chatham Island and at Te Puinga on Pitt Island. A survey done in late 1998 found 147 trees with carvings in 5 locations on Rehoa, with 82 trees at Hapapu. The carvings are mostly images of people, with many of them showing ribs, somewhat similar to the X-ray art found throughout the Pacific region. It has been speculated that at least some of the symbols represent the dead, based on the fact that in some, the figures have their knees pulled up to their chests, in the position that deceased Moriori were buried in dunes. There are also images of animals, such as flounders and birds, and one of a seal was found on Pitt Island. Others showed tree-like symbols and weapons, and many of the trees have horizontal carvings, like rings. The best known examples of momori rakau are at JM Barker (Hapupu) National Historic Reserve, where the carvings and trees are protected by a fenced enclosure and the protection of being one of only two National Historic Reserves in New Zealand. The reserve was fenced in 1980 to provide protection for the tree carvings from grazing stock and is now showing good recovery.
