Several Species Are Still Apparently Expanding Their Ranges And It Is Probably Only A Matter Of Time Before A Range Of Species Which Are Well Adapted To Grazing, Cool Temperatures And The Poor Soils Of Heathland And Acid Grassland Habitats Are Much More Widespread Unless Significant Action Is Taken To Control Them. These Species Include.. Pilosella Offinarum.
