What is the aim of the review?
To systematically collate and synthesise the available evidence in order to examine the effectiveness of bracken control interventions, to identify knowledge-gaps, and to provide an evidence-base to support decision making where bracken control is a problem.

The primary objective was to assess evidence on the impact of asulam on bracken abundance and to determine why the impact might vary. A secondary objective was the qualitative assessment of the impact of other bracken control interventions on bracken abundance.
