A Scottish bog woodland in dawn mist


Bogs, though similar to swamps or marshes, are a distinctive kind of wetland where peat forms from dead plant matter. Waterlogged conditions set this cycle going: still water holds little oxygen compared to flowing water, so plant material can't decay fully and slowly amasses. The decaying plants keep the oxygen level suppressed. Bogs are common in places with wet climates like Siberia, Ireland and Scandinavia.
