Return of the Wilderness to the UK?

[NorthernRaider]

I spose there will be lots of local variation, from fertility of soil to number of grass nimmblers like bunnies and sheep surviving to numbers of wild pigs and deers chewing on saplings. Some ponds with plenty of carp wont be inundated with pond weed others will soon clog up. The west of the UK tends to get more rain which will push plant growth more than over the east.
