Resumo(s)
Forest-fire rates have increased in Southern European landscapes. These fires damage forest
ecosystems and alter their development. During the last few decades, an increase in fast-growing
and highly fuel-bearing plant species such as bush, Eucalyptus globulus Labill., and Pinus pinaster
Ait. has been observable in the interior of Portugal. This study aims to verify this assumption
by the quantification of the biomass carbon sink in the forests of the Mação municipality. Maps
of fire severity and forest biomass evolution after a wildfire event were produced for the period
of 1991 to 2019. To quantify carbon retention in this region, this evolution was correlated with
gross primary production (GPP) on the basis of satellite imagery from Landsat 5, Landsat 8, and
MODIS MYD17A2H. Results show that wildfires in Mação increased in area and severity with each
passing decade due to the large accumulation of biomass promoted by the abandonment of rural
areas. Before the large fires of 2003, 2017, and 2019, carbon rates reached a daily maximum of
5.4, 5.3, and 4.7 gC/m2/day, respectively, showing a trend of forest-biomass accumulation in the
Mação municipality
