Is more complicated. Pines are "weak" creatures, always prone to be bullied and displaced by other trees in the lowlands, but they are survivalists. Pines grow in lands forbidden to other trees: high mountains, damp situations, sandy and the poorest soils.

When you had burnt the landscape stripped to the bone, to solid rock. When nothing grows, you put a pine and it will survive. Acid soil is better than no soil at all.

Some of this areas, when left alone, include slowly other species (holly, rowan), and dying pines, make interesting unique landscapes, peat bogs and moors. They host much more biodiversity than it could seem at first glance and a lot of endemisms also.
