| Effectiveness of Current Methods for the Control of Bracken
(Pteridium aquilinum) |
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.

At what stage is the review?
This review is now complete.
What is the rationale?
Control of bracken (Pteridium aquilinum) is a global problem for
livestock-based extensive agriculture, conservation, recreation,
game management and forestry. In the UK, bracken is a cause of
concern to the Royal Society for Protection of Birds (RSPB), Natural
England, and other conservation organisations as it is a potentially
invasive species on all ericaceous heath and acidic grassland
including nature reserves.
How were the results
obtained?
A number of electronic databases were searched for information
using a range of search terms. Bibliographies of retrieved articles
were checked for additional relevant references. Subject experts
were contacted for relevant publications. Over 2995 references
were retrieved in total. These provided 46 relevant data points
for metaanalysis of asulam impact, with a further 14 references
pertaining to bracken control by other means.
