Far from being upset, this lifts my spirits! It is great to see the removal of this sort of tree now with the knowledge that since they were planted, the long term management plans of many forestry areas are indeed geared towards the recreation of semi natural habitats, particularly heathland and broadleaf woodland. These trees were planted in less enlightened times and it is only the need for a reasonable financial return from the land - ie allowing the crop to fully mature - that is stopping the more rapid recreation of wildlife habitats. Your photo shows that we are one step closer to 'something better'.
Bring it on...!
