Introduction: Sustainable forest management focuses on securing environmental
services while maintaining aboveground biomass (BA) accumulation.
Objective: To evaluate the AGB along of a Chronosequence of temperate forest and to
examine the role of forest management for timber production on patterns of AGB
fixation, increment and allocation.
Materials and methods: A chronosequence of stands dominated by Pinus patula
Schiede ex Schltdl. & Cham. was selected in a range from 7 to 30 years. AGB was
estimated with allometric models and with parameterized models to infer the age at
which the managed forest reaches its maximum production. BA production, net aerial
primary productivity (NAPP), increments in BA and their allocation to tree structural
components were calculated and compared with those of a natural forest (NMF).
Results and discussion: AGB and APPN increased with stand age throughout the
chronosequence. The 30-year-old stand produced 79 % of the AGB observed in the
NMF. These two sites had high BA production, which corresponded to high APPN with
87 % similarity. Stems were the tree structural component with the highest AGB
allocation (70 %), mainly due to silvicultural practices such as thinning, which is part of
the forest management program.
Conclusions: P. patula forests with forest management accelerated the accumulation
of AGB in temperate forest stands along the chronosequence studied, reaching levels
similar to those of a NMF in a shorter period.
