Holme Post

This post shows subsidence of peatlands in the English fens south of Peterborough. The top of the post indicates ground level in the 1850s. This is now the lowest land in Britain, with sea level approximately at the level of the collar to which the guy wires are attached.

The subsidence of peat, which is mostly carbon-rich organic matter, is mainly due to microbial oxidation as a result of drainage and/or tillage.
