Tree Crown Data - MONTANE OSUG

This repository presents data on tree and crown dimension collected on four plots along an elevation gradient in the French Alps. These data have been collected in the framework of the OSUG project MONTANE : Multi-trophic biodiversity and multi-functionality across Alpine Environments. The objective of this project was to describe the forest three-dimensional structure and tree species diversity on several selected Orchamp gradients (see more details in [link](https://orchamp.osug.fr/)). In second step this field data were used to calibrate remote sensing methods to describe forest structure and composition at large scale at the individual level with lidar and hyperspectral data (see Tusa et al. 2020).
