Impact of plot size and model selection on forest biomass estimation using airborne LiDAR: A case study of pine plantations in southern Spain
airborne laser scanning forest inventory regression survey design genetic selection methods
2017/4/6
We explored the usefulness of LiDAR for modelling and mapping the stand biomass of two conifer species in southern Spain. We used three different plot sizes and two statistical approaches (i.e. stepwi...
Disturbance-induced changes in the plant biomass in forests near Plešné and Čertovo Lakes
aboveground biomass Picea abies forest
2015/5/18
Two forested catchments in the Bohemian Forest (Šumava Mts.) were investigated according to the species
composition of herb layer and aboveground plant biomass. The bark-beetle gradation was ob...
Biomass allocation influenced by canopy closure in a young spruce stand
tree allometry repeated sampling
2015/5/18
Growth intensity of particular tree components is controlled by a variety of factors and as a consequence,
biomass allocation also changes over time. Since the allocation of biomass controls the car...
Using linear mixed model and dummy variable model approaches to construct compatible single-tree biomass equations at different scales – A case study for Masson pine in Southern China
aboveground biomass dummy variable model linear mixed model Pinus massoniana
2015/4/14
The estimation of forest biomass is important for practical issues and scientific purposes in forestry. The estimation of forest biomass on a large-scale level would be merely possible with the applic...

This study is focused on substitute European larch stands in the Krušné hory Mts. (northern part of the Czech Republic). Research was conducted within larch thinning experiment Kalek (780 m a.s.l...
Models for predicting aboveground biomass of European beech (Fagus sylvatica L.) in the Czech Republic
beech biomass function temperate forests tree allometry wood density
2015/5/6
We developed optimal models for predicting the aboveground biomass of European beech (Fagus sylvatica L.) applicable to the national forest inventory data of the Czech Republic. The models were based ...
