Abstract/Contents:"The program of vegetation management for rights-of-way at Southern Illinois University, Carbondale was initiated in 1990 by Drs. Gerald Gaffney and David Shanaut. The purposes of the program are threefold. The first purpose is to test and demonstrate the effectiveness of herbicides in the control of woody species. The second purpose is to serve as a center for the dissemination of information and training of the personnel in the rights-of-way industry. The third purpose is to determine if any and which plant species are encouraged by herbicide use in species succession adjacent to forests. Plots were treated at various concentrations and combinations of the chemicals listed in Table 1. Applications were: bareground granular, low volume foliar, high volume foliar, Z strip foliar, low volume basal, and aerial simulation. Plot size ranged from 12 by 12 m to 12 by 65 m. Data were collected from demonstration and research plots that had been treated in 1991, 1992, and 1994. Surviving species were recorded from the plots treated in 1994. From the plots treated in 1991 and 1992, frequencies of encroaching species were recorded. Species are divided into two categories listed in Table 2 as grass and brush, and in Table 3 as trees. After treatment in 1994, honeysuckle, raspberry, and yellow foxtail were released to dominate the plots. Oaks and red cedar frequently tolerated the herbicides. Since treatment in 1992, honeysuckle vine, raspberry, and broomsedge are the most prevalent associated species. Bareground granular applications appear to encourage broomsedge dominance, while foliar applications appear to encourage honeysuckle and raspberry dominance. Among the tree species, autumn olive is the only one to be more invasive. Three years after the 1991 treatment, honeysuckle, raspberry, broomsedge, and yellow foxtail continue to dominate the plots. Kentucky bluegrass, fine fescue, and tall fescue are appearing in spots. Autumn olive, shingle oak, and red cedar also continue to be the dominant tree species with the addition of American elm. A more broad array of tree species are present. Data from these plots will be recorded a minimum of seven years after treatment."
