Comment on Swathes of Cairngorms unrecognisable after 12 days of ‘cataclysmic’ wildfires
shish_mish@lemmy.world 2 days agoThat was my first thought.The peat that causes the fire to keep burning underground, also makes a good soil for trees and all the understory needed. But the heather roots are left behind by the fire and wouldn’t they need removing first otherwise it would just grow back impeding the trees?

As long as they plant trees that have had a few years in a nursery first they should be able to coexist despite the roots. Heather roots are quite shallow, tree roots would generally be able to penetrate deeper underneath them. Eventually the canopy of the trees would kill off the heather allowing other plants to come through.
The biggest issue would be keeping the deer numbers low enough to allow the trees to establish and become mature.
That’s one of the reasons why there’s been a push to reintroduce wolves and lynx, to keep deer numbers manageable because decades of hunting and culls haven’t been working.
