Are there concerns with illegal logging in the monarch overwintering habitat in Mexico?

Most importantly, logging that occurs in the core zone of the Monarch Butterfly Biosphere Reserve is illegal. It is neither widespread nor common, but just as illegal things occur in the U.S., illegal things occur in Mexico when people profit economically by committing crimes. Both the local people and the government work hard to enforce the laws, but the area is huge, there is some collusion with some community members, and some large cartels are getting involved in illegal lumbering. There is also a large demand for the lumber, some of which ends up in the US. There are many organizations working together with the government and communities in the area to reduce and stop illegal logging.
