Control of exotic annuals is often a priority when restoring degraded grasslands or shrublands. This study evaluated combinations of nutrient‐depleting (carbon addition) and seed bank‐depleting approaches for controlling exotic annuals, and compared the seed bank depletion technique of spring burning with the more easily applied technique of pulse grazing. Treatments were applied in two Box Gum woodlands...
Restoration goals often involve the addition of new species to resident, degraded communities but in box gum woodlands such restoration is often constrained by competition from persistent exotic annuals that control critical ecological processes. Nutrient reduction (via carbon addition) and seed bank depletion are two approaches to reduce competition from exotic annuals but to be effective these treatments...
While the mechanisms behind the control of exotic annuals by C4 native grasses on soils of low fertility are well understood, it is not clear how C3 native grasses sometimes achieve similar levels of control. In earlier research (Cole I. A., et al., 2016a, Aust. Ecol. 41, 40; Cole I. A., et al., 2016b, Restor. Ecol. 24, 354), the abundance of cool season exotic annuals waxed and waned over time, apparently...
