. Carbon Storage in Protected Areas – Technical Report. . Soil carbon - Canada The Soil Organic Carbon Digital Database of Canada (Tamocai & Lacelle 1996) is based on the Soil Landscapes of Canada (SLC version 2), part of the National Soils Database, and maintained by the Eastern Cereal and Oilseed Research Centre of Agriculture and Agri-Food Canada. The Canadian SOC Database provides estimates for carbon density and total stock for over 10,000 landscape units representing the whole territory of Canada (Figure 7). The equivalent estimate from the global SOC map is presented in Figure 8. Ca

Comparison of the maps derived from these two datasets reveals substantial differences both in relative abundance of carbon across geographical regions and in absolute values of carbon stock in high density areas. In particular, the national dataset depicts vast territories in the Canadian north and across sub-arctic islands as areas in which soil carbon density exceeds 300 tons/ha, whereas no density above 200 t/ha is identified for these territories from a global dataset. The high carbon "belt" expanding from north-west Canada through its central part towards south-east part seems to be depicted similarly by both datasets, but soil carbon density differs considerably. The maximum density identified by a global dataset is 822 t/ha and only 53,000 km" is identified with density above 800 t/ha. In contrast, the regional dataset shows the extent of the territory with carbon density above 800 t/ha to exceed 839,000 km" and within this, 115,000 km" has an estimated density in exce
