Climate change has significant effects on forest ecosystems around the world. Since tree diameter increment determines forest volume increment and ultimately forest production, an accurate estimate of...
Heritable variation in tree growth and needle vegetation indices of slash pine (Pinus elliottii) using unmanned aerial vehicles (UAVs)
Pinus elliottii Heritable variation UAVs
2023/6/2
Vegetation indices (VIs) are mainly associated with plant yield, and yield-related physiological traits can assist in breeding selection. Tree breeding programs require a rapid assessment of a large n...
UAV-BASED AUTOMATIC TREE GROWTH MEASUREMENT FOR BIOMASS ESTIMATION
UAV point cloud biomass estimation tree height
2016/11/30
Manual in-situ measurements of geometric tree parameters for the biomass volume estimation are time-consuming and economically non-effective. Photogrammetric techniques can be deployed in order to aut...
The effect of coppice management on the structure, tree growth and soil nutrients in temperate Turkey
coppice soil growth dynamics forest management
2015/5/18
Coppicing was widespread throughout Europe for many centuries but was largely abandoned in the second half
