Economic Importance for Humans: Negative
The cocoa industry is fairly large in Brazil. Because cocoa plants grow best in shade, plantation owners prefer to have forests surrounding their crop. Therefore, a few of the forests that would have been destroyed for development have been left intact (Nowak and Paradiso 1983).
The tamarins, after being pushed out of their native forests, have started to move into these plantation forests. Many plantation owners have complained that this movement is adversely affecting their crop (Nowak and Paradiso 1983).
