| Abstract: | The grazing of 3 relatively productive grasslands ( Festucaf Agrostis ) by hill sheep was examined in relation to herbage consumption, grazing pressure, dung deposition and the number of sheep in the area. Herbage intake ranged from 400 Ib/ac/annum (dry weight) on the highest (2450 ft O. D.) and most exposed grassland to 800 Ib/ac/annum on a grassland (1700 ft O. D.) adjacent to extensive heather moorland on blanket bog. The highest pressure (5·5 sheep/ac) was also found on grassland surrounded by blanket bog (1 sheep/14 ac). |
