Ecological Consequences of Using Prescribed Fire and Herbivory to Manage Juniperus Encroachment Before European settlement and their introduction of stock-farming practices, these vegetation communities were maintained by periodic fires (Frost 1998) and the grazing/browsing habits of native wildlife (Smeins et al. 1997). These early ranchers did not have experience in semiarid regions, and co
