ABSTRACT
A comprehensive review of the Journal of Range Management indicated that there were far more scientific papers published on chemical woody plant control than any other method in the last 50 years (Table I). This is true regardless of the time period investigated. Even in the last 1 ()..year period ( 1990 to 2000) more papers were published about using herbicides than about using fire or biological or mechanical means. Economic constraints and governmental restrictions have been particularly operative against chemicals, beginning in the 1970s. More than 54 papers were published on chemical brush control in each of the two decades from 1970 to 1990. Even during the 1980s, when prescribed burning was reemphasized, there were still more than twice as many papers published about using herbicides (55) versus fire (26). These numbers do not include chemicals used in integrated brush management systems (IBMS) or in papers in which several methods were compared (Table 1 ). It clearly shows the importance of herbicides or the perceived importance of herbicides in woody plant control, whether used alone or with other methods.
