abstract = "Tropical rainforests store enormous amounts of carbon, the
protection of which represents a vital component of efforts to
mitigate global climate change. Currently, tropical forest
conservation, science, policies, and climate mitigation actions
focus predominantly on reducing carbon emissions from
deforestation alone. However, every year vast areas of the humid
tropics are disturbed by selective logging, understory fires, and
habitat fragmentation. There is an urgent need to understand the
effect of such disturbances on carbon stocks, and how stocks in
disturbed forests compare to those found in undisturbed primary
forests as well as in regenerating secondary forests. Here, we
present the results of the largest field study to date on the
impacts of human disturbances on above and belowground carbon
stocks in tropical forests. Live vegetation, the largest carbon
pool, was extremely sensitive to disturbance: forests that
experienced both selective logging and understory fires stored, on
average, 40% less aboveground carbon than undisturbed forests and
were structurally similar to secondary forests. Edge effects also
played an important role in explaining variability in aboveground
carbon stocks of disturbed forests. Results indicate a potential
rapid recovery of the dead wood and litter carbon pools, while
soil stocks (030 cm) appeared to be resistant to the effects of
logging and fire. Carbon loss and subsequent emissions due to
human disturbances remain largely unaccounted for in greenhouse
gas inventories, but by comparing our estimates of depleted carbon
stocks in disturbed forests with Brazilian government assessments
of the total forest area annually disturbed in the Amazon, we show
that these emissions could represent up to 40% of the carbon loss
from deforestation in the region. We conclude that conservation
programs aiming to ensure the long-term permanence of forest
carbon stocks, such as REDD+, will remain limited in their success
unless they effectively avoid degradation as well as
deforestation.",
