Integrated bracken control and vegetation restoration - BD0504

Description
The development of vegetation following bracken control programmes is slow and unpredictable; little information exists on methods for accelerating the rate of vegetation restoration in bracken control areas. This study will aim to determine the effects of different bracken control methods on vegetation development. Impacts of litter layer removal, seeding, use of nurse crop and fertilizer addition will also be investigated and the effectiveness of controlling bracken fronts at preventing bracken expansion will be assessed. Bracken-treated areas will be surveyed using a chronosequence approach to assess responses of vegetation to previous asulam application. A range of integrated treatments will be evaluated experimentally for their ability to meet the following 2 criteria: effective long-term bracken control; and successful establishment of suitable vegetation. Existing models will be used to predict the effectiveness of control and revegetation treatments beyond the 3 year study period and treatments will be costed in order to recommend the most effective approach to bracken control. Results will be of immediate value to farmers, land owners and other interested parties attempting to re-instate vegetation after bracken control.
