Between 1990 and 1996 a range of follow-up strategies were applied to a permanent meadow in Bulgaria infested with bracken (Pteridium aquilinum), which was recovering after initial control using glyphosate. The initial glyphosate treatment (4·3 kg ha-1) reduced both the bracken infestation and the underlying weedy vegetation, and facilitated the recovery of pasture species. However, there was rapid bracken recovery within 5 years where no follow-up treatment was applied. Cutting twice yearly slowed recovery, but the most effective treatments were where (1) there had been a single follow-up weed wiping application of glyphosate plus cutting twice yearly, or (2) where Festuca rubra and Vicia cassubica were sown. Reseeding on its own or combined with cutting twice yearly provided good bracken control and a high forage quality over the 5 year period.
