Abstract
The control of invasive exotic plant species in sites of high conservation value should minimize both the impacts on the ecosystem of concern and the potential for regeneration of the exotic species. We examined how the method and timing of the removal of the invasive shrub Scot's broom (Cytisus scoparius) affected the level of site disturbance and subsequent broom regeneration from seed and resprouting in remnant Garry oak (Quercus garryana) meadow communities in Victoria, British Columbia. We compared manual uprooting versus cutting at two time periods: May, when the shrub was in flower, and in July, just prior to seed dispersal. Soil disturbance, trampling, and seedling regeneration were significantly higher in plots when broom plants were uprooted as compared to plots where broom plants were cut at the base. Amount of trampling was higher in July than in May, but in July the trampled plants were exotic grasses, while in May these included fruiting stalks of native common camas (Camassia quamash). Resprouting of cut stems was observed in only 7 of the 75 broom stems cut and these died-back within one year. These results suggest that the preferred Scot's broom removal strategy in Garry oak meadow communities of high conservation value is to cut broom after native herbaceous species have set and distributed seed. This approach will minimize damage to native vegetation and reduce the amount of broom seedling regeneration
