From the New York Times:

In the United States, forests are not being illegally logged on a systemic scale, as is the case in countries like Indonesia, Malawi and Brazil, where unauthorized harvesting has led to serious deforestation and attendant environmental problems. Here, the issue is often scattered and intimate, and often affects homeowners, parks and public forests.

In Flint, Mich., for instance, thieves last month stole black walnut trees from the grassy landscaped edge of a main city street. Earlier last year, people were snatching saplings from a city park there as soon as they were planted.

Globally, the Illegal Logging market is $15 billion.
