Carbon cycle fieldwork

Carbon in soils and in cities

David Holmes provides further ideas for carbon cycle fieldwork, based on estimating carbon storage in soils and carbon fluxes in the urban environment

Peatlands are widespread in the UK uplands

The last Geographical Skills column, in Vol. 31, No. 1, looked at how to measure biomass in woodlands. This column suggests more carbon cycle fieldwork which uses simple sampling and quantitative skills to estimate stores or fluxes of carbon.

Peatlands are widespread in the UK. They are upland areas covered with a thick organic soil (peat) made from partly decayed vegetation and are thus a rich store of carbon (see the article about tropical peatlands on pp. 16–19). UK peatlands store approximately 5.1 billion tonnes of carbon in total. This is half of all UK soil carbon and an order of magnitude higher than the carbon stored in vegetation.
