From the text ... 'Fire has been used for many good reasons in addition to natural ecosystem management. Native Americans used fire to open the landscape for hunting, as is done now on many hunting reserves. Fires have been used to clear otherwise shrubby woods for ease of access, for example, for the turpentining business in the Southeastern longleaf pinelands. Fire has been useful in agriculture for clearing the ground of plant debris and releasing nutrients for the next crop. It is also used to burn debris following logging operations and to eliminate hardwood and shrub competition in pine plantations, among other purposes. It is much less expensive than using herbicide to reduce unwanted plants, and therefore it has continued to be used as a management tool in some areas.'
