Areas dominated by bracken (Pteridium
aquilinum) forming greater than 50% ground cover have been mapped primarily on
upland farms or moorland fringes or steep slopes extending along valley sides.
This feature can be difficult to interpret as the photograph tones vary
throughout the year in accordance with the bracken growth phases. Bracken is
most extensive within a warm or mild, moist climate with some element of
shelter from frosts and strong winds, a relatively fertile soil and free
drainage. The total number of plant species in a dense bracken stand is small
and grazing value is highly restricted.
