Vegetation development on upland and marginal land treated with herbicide, for bracken (Pteridium aquilinum) control in Great Britain

Article Abstract:

A survey into the impact on associated vegetation of spraying with asulam to control bracken (Pteridium aquilinum), found that control procedures do successfully control bracken, although there are significant regional variations in vegetation development.

Heathland seedbanks under bracken Pteridium aquilinum (L.) Kuhn and their importance for re-vegetation after bracken control

Article Abstract:

The re-vegetation of heathland seedbanks with bracken control shows variations in site characteristics as the distance into each bracken patch increases. The size and distribution of seedbanks along transects through areas of moorland invaded by bracken in UK is surveyed by correlation and linear regression. Calluna vulgaris is the predominant species in the bracken encroachment sites. Seedbank is reduced in lands which have been under bracken for a considerable time. Where bracken invasion is recent, seedbanks are preserved or destroyed depending on the presence of litter in the soil.

An assessment of aerially applied asulam as a method of long-term bracken control

Article Abstract:

An assessment was made on the vegetation of 117 bracken-dominated sites sprayed with asulam from the air over a wide range of dates. High variability in initial efficacy was recorded, as well as differences in regeneration displayed by the sites in the years following treatment. Sites treated for more than 10 years showed good control of bracken. Results suggested that aerial spraying of bracken with asulam can be a long-term and cost-effective control method.
