Alpine ecosystems have a clear distribution of species that are limited by their environment. Climate change can alter the bio-climatic zones and change the distribution of some species. Trees of a single species have different physiognomy at the optimal conditions than at the extremes of their niche (smaller and more stressed trees). Most research on plant stress detection with remote sensing has been focusing on visible-near infrared (VISNIR). However, the thermal infrared (TIR) seems to contain valuable information on Leaf Water Content (LWC) and structural and microstructural traits of leaves, which could be used as proxies for plant stress detection. This study explores changes in the TIR in relation to imposed plant stress.
