Abstract
Abstract Vegetation dynamics in partially improved heather-gorse shrublands were studied in a 3-year field experiment under single or mixed grazing of sheep and goats. The experimental plots comprised untreated heathland, mechanically cleared heathland and converted heathland to grassland (perennial ryegrass-white clover improved pasture, covering 33–50% of the total plot area). In the heathland and mechanically cleared areas, the accumulation of shrubs in terms of cover, height and phytomass was more controlled by goats than by sheep, with intermediate values for mixed treatments. The differences were mainly restricted to the gorse ( Ulex gallii ), while the ty...
