 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.
