Increase number of livestock Shrubland and Heathland Conservation

A site comparison in 10 heathland sites that were subject to grazing in the UK (Pakeman & Nolan 2009) found that the cover of common heather Calluna vulgaris increased in sites with low sheep density and declined in areas with high sheep density. Common heather cover increased in sites where there were fewer than two sheep/ha and declined when there were greater than two sheep/ha (data reported as model results). Heather cover was estimated in seventy four plots across the 10 sites. Stocking density at the sites varied between zero and six sheep/ha.
