may hire other relatives or strangers if faced with a large order. However, only the most established of carving families can have any permanent outside help and a number of these refuse to hire outsiders. Copal wood Almost all alebrije carvers in Oaxaca use the wood of trees from the genus Bursera (Family Burseraceae), with a preference for the species B. glabrifolia, which is locally called copal or copalillo. This tree is typically found in dry tropical forests in Oaxaca and neighboring states. The exceptions are Isidro Cruz of Tilcajete, who uses "zompantle" (Erythrina coralloides) and the Manuel Jimenez family, which carves in tropical cedar (Cedrela odorata) imported from Guatemala. Originally, carvers obtained wood from the local forests on their own. Copal trees are short and squat and do not yield much wood; every piece is used. Despite this, the success of woodcarving caused an unsustainable drain on local wild copal, and nearly all of the trees near Tilcajete and Arrazola have disappeared. This localized depletion soon gave rise to a copal wood market in Oaxaca, even though many of the copal trees in other parts are of a different subspecies, which has more knots. Obtaining wood is a complex exercise because negotiating with other municipalities requires navigating complex social, legal and economic norms, and in many cases, state and federal environmental authorities have stepped in to try to preserve wild copal trees in a number of areas. Some communities have simply refused to sell their wood. These difficulties has led to a black market in copal wood, with carvers purchasing most of their supplies from venders called "copaleros." Harvesting copalillo is not a complex task; trees are relatively small and the wood is soft. Trees are felled using an axe or chainsaw. Branches are cut with machetes. Most harvesting occurs on ejidal (communal) lands. Legal or not, the purchase of copal wood from other parts of Oaxaca is putting unsustainable pressure on wild populations in a wider area, forcing copaleros to go further to obtain wood and often to deal with angry locals and police who alternately seek bribes and enforce the law. Eventually, this led to about only six copaleros which control most of the wood being sold, and these supplies' being unreliable. The federal government states that most of the figures are made with illegally obtained wood. Securing supplies of copal wood is a major concern for
