Bracken and the Asulam Ban
Knowledge Scotland has published a briefing by Professor Robin Pakeman that summarises the amount of bracken controlled by the aerial application of asulam in the period 1978 - 2010. It provides an estimate of what the bracken cover might have been if asulam on this scale had not been applied.
The estimated 50% reduction in the area of bracken that has been achieved in this period certainly provides some justification for the importance of the work to maintain the availability of asulam.
Dr Dick Birnie has provided three of his papers prepared whilst working at the Macaulay Institute. These can be accessed from the links below:
- An assessment of the bracken problem in relation to hill farming in Scotland
- The Bracken Problem in Scotland: A new assessment using remotely sensed data
- The potential distribution and impact of bracken in Upland Scotland: an assessment using a GIS-based Niche Model

Horse Drawn Bracken Bruising. The control options for bracken are many and varied. A horse-drawn bracken bruiser can be seen in action in the top photo in the margin but see the Heavy Horses website for further information.
Tick bites and Lyme disease. See the factsheet and best practice guide for forest users issued by the Royal Forestry Society. The relevance to bracken is the strong association between bracken litter and high sheep tick densities - the litter provides an ideal habitat for ticks.
LERAP = Local Environment Risk for Pesticides. Certain pesticides have an aquatic buffer zone requirement when applied by horizontal boom or broadcast air-assisted sprayers. To reduce this aquatic buffer zone, there is a legal obligation to carry out and record a Local Environment Risk Assessment for Pesticides.
