Weston. Herbicide treated plots had significantly less total cover than all other disturbance
treatments (Table 15). The fertilized Tilled plots had significantly less total cover than all but
the Herbicide treated plots. After two growing seasons, there were fewer differences among
disturbance-fertilizer combinations. The only significant differences found in Fall 2004 were
between fertilized and unfertilized Control and Seeded plots (unfertilized plots had higher total
