Finalizing Avoided Deforestation Baselines
Changes in carbon stocks
The carbon density estimates used per vegetation type are summarized in Table 19 (from A. Ordoñez,
2003, personal communication).
Table 19. Carbon density estimates for vegetation found in the region Purepecha.
Vegetation Type
T C/ha
Agriculture 4
Pasture 5
Shrubs 7
Forest Plantation 39
Permanent Crops (Orchards) 42
Pine-Oak Forest 77
Pine Forests 84
Oak Forests 95
Oyamel Forest 110
The change in forest cover was then matched with data on carbon stocks of the various vegetation types.
A map of carbon densities is shown in Figure 24.
Figure 24. Biomass carbon density map for the Meseta Purépecha region.
The map of the rate of change in land-use was combined with the carbon density map to generate a
graph of carbon stocks through time (Figure 25). Most of the change in stock occurs in the pine-oak
forest as this forest type is converted to lower stock agriculture or avocado plantations.
