Wild Boar became extinct in Britain in the 13th.C. At that time Britain was a very heavily wooded country. Since then vast numbers of trees have been felled to supply timber for a multiplicity of purposes. Houses, Englands 'Wooded Walls' i.e. The Royal Navy, commercial ship building, Charcoal production for the iron and steel smelting industry and for Gunpowder production, household fires, Gun carriages, etc the list could be made almost endless.
However, the point is that the Wild Boar was and still is, a forest dweller and Britain is really lacking in Broadleaf forest, very little of which has been, or is being, planted, having been taken over by Conniferous woodland, a habitat that is totally unsuitable habitat for Boar. Boar can do a lot of damage in the now restricted areas of Broadleaf forest and that can prevent regeneration of not just trees but also many flowering plants. So it's hardly surprising that they are being culled to reduce their numbers
I like wild boar but it's presence in Britain should be managed correctly. Finally a wild boar that may possibly think it is endangered can become a very vicious animal, being savaged by one is not funny at all.
