Perhaps you need to look at forestry as a possibility? A recent survey shows that investment in UK forestry is running at an all time high. This specialised form of investment is not for everyone, even more so than agricultural land, and does have particular risks and dangers, but it is interesting that, as a long term investment, some are branching out into it. (Sorry!)
Investment in UK forestry is at a record high, according to a joint report by Tilhill Forestry and John Clegg & Co.The UK Forest Market Report found that £151.15m ($160.8m) worth of productive forests were traded in 2014.A total of 98 properties – or 18,435 hectares – were sold last year. This year, UK timber production is up to 11.4m tonnes, driven by standing timber prices, now at their highest since 1998.
