dc.description.abstract | Aims of study: To evaluate the potential use of canopy height and intensity distributions, determined by airborne
LiDAR, for the estimation of crown, stem and aboveground biomass fractions.
To assess the effects of a reduction in LiDAR pulse densities on model precision.
Area of study: The study area is located in Galicia, NW Spain. The forests are representative of Eucalyptus globulus
stands in NW Spain, characterized by low-intensity silvicultural treatments and by the presence of tall shrub.
Material and methods: Linear, multiplicative power and exponential models were used to establish empirical
relationships between field measurements and LiDAR metrics.
A random selection of LiDAR returns and a comparison of the prediction errors by LiDAR pulse density factor
were performed to study a possible loss of fit in these models.
Main results: Models showed similar goodness-of-fit statistics to those reported in the international literature. R2
ranged from 0.52 to 0.75 for stand crown biomass, from 0.64 to 0.87 for stand stem biomass, and from 0.63 to 0.86
for stand aboveground biomass. The RMSE/MEAN · 100 of the set of fitted models ranged from 17.4% to 28.4%.
Models precision was essentially maintained when 87.5% of the original point cloud was reduced, i.e. a reduction
from 4 pulses m–2 to 0.5 pulses m–2.
Research highlights: Considering the results of this study, the low-density LiDAR data that are released by the
Spanish National Geographic Institute will be an excellent source of information for reducing the cost of forest
inventories. | es |
