 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.
