Carbon (C) stocks for southeast Mexican forests for the years 1990-1991 were calculated by two different methods. The first method multiplied land area of each forest by C densities of phytomass, necromass, and soil-organic matter. A digital map derived from Advanced Very High Resolution Radiometer (AVHRR) imagery provided forest areas. Carbon-density values were obtained from ecological studies reported in the literature. The second method calculated C densities from climate-based regression models for each forested pixel in the AVHRR cover map. A combination of the two methods was used to calculate C stocks because neither approach was suitable for all forests. Land area was estimated as 13 Mha for the tropical evergreen forest, 7 Mha for the tropical deciduous forest, and 7 Mha for the oak-coniferous forest. Carbon stocks for tropical evergreen, tropical deciduous, and oak-coniferous forests were 3.12, 1.30, and 0.92 PgC, respectively. The southeast forests contribute approximately 40% to total C stocks in all Mexican forests. |
