Abstract
Abstract. Boreal forests are particularly vulnerable to climate warming,
which increases the occurrence of natural disturbances, such as fires and
insect outbreaks. It is therefore essential to better understand
climate-induced changes in boreal vegetation dynamics. This requires
accurate estimates of variations in biomass across regions and time. This
remains challenging in the extensive larch forests of northeast Siberia
because of the paucity of allometric equations and physical properties of
woody debris needed for quantifying aboveground biomass pools from field
surveys. Our study is the first to present values of mean squared diameter
(MSD) and specific gravity that can be used to calculate fine dead and
downed woody debris loads in Cajander larch (Larix cajanderi) forests using
the line-intersect sampling approach. These values were derived from field
measurements collected in 25 forest stands in the Republic of Sakha, Russia,
and compared with values reported for other prevalent boreal tree species.
We developed allometric equations relating diameter at breast height (DBH, at 1.3 m) to stem wood, stem bark, branches, foliage, and aboveground biomass based on measurements of 63 trees retrieved from previous studies.
Differences between our allometric models and existing equations were
assessed in predicting larch aboveground biomass in 53 forest stands sampled
in the Republic of Sakha. We found that using fine woody debris (FWD)
parameters from other boreal tree species and allometric equations developed
in other regions may result in significantly lower biomass estimates in
larch-dominated forests of northeast Siberia. The FWD parameters and
allometric equations presented in our paper can be used to refine estimates
of aboveground biomass in Cajander larch forests in northeast Siberia.
