| Zusammenfassung |
| The distribution of carbon in the different ecosystem stocks may change with direct human
perturbation or climate change. We present a detailed description of the carbon stocks of an
old-growth forest and an anthropogenic peatland (i.e., created by flooding, as a consequence
of forest fires or logging). The study area was located in a private reserve in the
Chiloé Island, southern Chile (41°52’ S, 73°40’ W). Sampling was done on plots
separated 60 m from each other, in areas of approximately 30 ha for each ecosystem
type. Total C was 1523 ± 117 Mg ha-1 in the forest and 130 ± 13.8 Mg ha-1 in
the peatland, with 69.7% and 91.7% of this found belowground, respectively. In
the forest, the necromass stock composed by logs and snags was high (183 Mg C
ha-1), compared with the live-tree stock (264 Mg C ha-1) and with the C stored
in the understory vegetation (14 Mg C ha-1). In the peatland, most of the C was
stored in the most decomposed layer of peat, deeper in the ground. Because the
anthropogenic peatland is experiencing a secondary succession, there is great potential to
sequester back the C lost due to the perturbation. However, in most of the area where
these ecosystems are found, the moss is being harvested for horticultural purposes. |
