Marker 5The Scots pine is a typical example of a dynamic, sun-seeking species that colonises soils impoverished by centuries of grazing. Its winged and light seeds can be carried over several hundred metres by the wind, thus enabling it to spread rather quickly. Here we are in a young pine forest that is winning the battle against callune (heather). Its pale foliage lets light penetrate to the undergrowth and enables other species (oak, beech or fir) to grow. They will eventually dominate the pines by depriving them of light.
