Footnotes (BACK TO TOP)

1. Occasionally, land cover (GLC2000) forest pixels fell within ecofloristic zones (referred to as ecoregions hereafter) where GLC2000 did not logically match the ecoregion description i.e. GLC2000 forest class pixel within a tropical desert ecoregion. In such instances, we made best guesses as to the best carbon value to apply.
   • When a GLC2000 forest class pixel fell within a tropical desert or tropical shrubland ecoregion, we used the carbon value for tropical dry forest.
   • When a GLC2000 forest class pixel fell within a subtropical desert or subtropical steppe ecoregion, we used the carbon value for subtropical dry forest.
   • When a GLC2000 forest class pixel fell within a temperate steppe or temperate desert ecoregion, we used the carbon value for temperate continental forest.
   • When a GLC2000 forest class pixel fell within a boreal tundra woodland or polar ecoregion, we used the carbon value for boreal coniferous forest.
2. Although their frequency was low, we encountered several instances where the Intergovernmental Panel on Climate Change (IPCC) tables lacked adequate information or did not match up with the input vegetation layers. In such instances, we applied a carbon value from the next best fit.
• Australia and New Zealand were not fully described by the IPCC so we applied the global average carbon values except in the case of temperate oceanic forest in New Zealand, which we also applied to Australia.
• For GLC2000 forest class pixels that fell within subtropical ecoregions in Europe, we used carbon values from GLC2000 forest class pixels falling within subtropical ecoregions in continental Asia.
• For GLC2000 forest class pixels that fell within subtropical humid forest ecoregions in Africa, we used the global average carbon value for GLC2000 forest class pixels falling within subtropical humid forest ecoregions.
• For GLC2000 shrubland class pixels that fell within any temperate ecoregion, we used the value from Mediterranean shrubland in Roy, et al. (2001) because no value for temperate shrublands was given by IPCC.
3. The IPCC tables only defined carbon density values for grasslands in terms of temperature (i.e. tropical, temperate, etc.) and precipitation (wet or dry). Therefore we had to aggregate ecoregions to match the descriptions from the IPCC tables. In some ambiguous cases (e.g. precipitation regimes of mountain systems), we took the average of more than one possible case.
   • For GLC2000 grassland class pixels that fell within a tropical mountain system or subtropical mountain system ecoregions we averaged the IPCC values for tropical moist & wet and tropical dry.
   • For GLC2000 grassland class pixels that fell within a temperate oceanic forest ecoregion, we averaged the IPCC values for cold temperate wet and warm temperate -wet grasslands.
   • For GLC2000 grassland class pixels that fell within a temperate continental forest or temperate mountain system ecoregion, we averaged the IPCC values for cold temperate wet, warm temperate -wet, cold temperate dry, and warm temperate dry grasslands.
   • For GLC2000 grassland class pixels that fell within a temperate steppe or temperate desert ecoregions, we averaged the IPCC values for cold temperate dry and warm temperate -dry grasslands.
