Data related to carbon storage capacities of forests
have become very important through global warming. After
Kyoto Protocol, countries need to see carbon storage abilities of their forests to perform true declarations. So, we
aimed to set allometric biomass and carbon equations suitable for predicting above-ground biomass and carbon
amounts and conversion of standing stem volume to stored
carbon values of above-ground tree components for Uludağ
Fir trees. Based on data obtained 34 sample trees which
symbolized diameter classes (4-60 cm), above-ground
biomass development of Uludağ fir was modeled according
to tree components. Carbon concentrations of tree components were established with the help of samples taken from
sample trees. The biomass and sequestered carbon were
modeled from the standing stem volume of single trees, in
order to allow calculation of the carbon sequestered in
stands. The study tested different models in determining
biomass as a function of DBH or DBH and H. Appropriate
functions were chosen and used in the estimation of biomass. Carbon concentrations were found to be lowest in
branch barks, with a ratio of 47.0% and highest in needles,
with a ratio of 53.5%. The present study make it possible to
attain –above-ground biomass and sequestered carbon
values safely and without any auxiliary operation by using
the standing stem volume, which is the most practical
element in management plans.
