| الوصف: | Carbon ( C ) stocks in forest soils were evaluated in the first comprehensive survey of G reat B ritain, the B io S oil soil survey, using a total of 167 plots (72 in E ngland, 26 in W ales and 69 in S cotland). The average C stock down to 80 cm depth for seven main soil types ranged between 108 and 448 t C /ha with maximum values from 511 to 927 t C /ha. Carbon stock varied with soil depth and type, forest type, and stand age. Stocks within the upper mineral soil (0–20 cm) represented between 29 and 69% of the total 0–80 cm C stock, while those in the top 40 cm comprised 59–100% of the total. Carbon stocks decreased in the order deep peats > peaty gleys > groundwater gleys > surface‐water gleys > podzols and ironpans > brown earths > rankers and rendzinas. Litter and fermentation horizons on average contributed an additional 7.3 and 8.8 t C /ha, respectively, to the overall soil C stock. Measured soil C stocks (0–80 cm) were upscaled by area of main soil and forest types to provide national estimates. Total forest soil stocks for E ngland, W ales and S cotland were upscaled to 163, 46 and 337 M t C , respectively, with an additional 17, 4 and 21 M t C within surface organic layers (litter and fermentation horizons). Carbon stocks were larger under conifers compared with broadleaves. Peaty gleys contributed most to the total C stock in S cotland, while brown earths and podzolic soils made the largest contribution in W ales, and brown earths and surface‐water gley soils in E ngland. Estimated total carbon stocks in forest soils in G reat B ritain, including organic layers, are 589 M t C in the top 80 cm and 664 M t C in the top 1 m of soil. The B io S oil soil survey provides the most comprehensive estimate of forest soil C stocks in G reat B ritain to date and provides a good baseline for assessing future change even though variability in forest soil C stocks is high. However, a relatively small number of additional plots to fill existing gaps in spatial coverage and to increase ... |
