206FA/2020 – 3DCAM- Multi-spectral, 3D camera monitoring of alpine plant communities after experimental warming
Résumé du projet
Climate change is threatening the structure and functioning of mountain plant communities. However, so far, future scenarios are mostly based on static modelling approaches that focus on abiotic drivers and ignore biotic interactions, transient dynamics, and potential acclimatization of species traits and phenology. To better understand dynamic responses of plant communities to climate change, scientists have recently started large-scale transplant experiments where entire little ecosystems are translocated to places with environmental conditions resembling those expected in the future. While these experiments allow studying fine-resolution, long-term responses of different facets of plant community structure and functioning to climate change, sampling all the necessary data within and across years remains extremely time consuming. Therefore, with CamCom we propose to develop and test a workflow based on close range remote sensing techniques with multi-spectral cameras and a 3D sampling approach towards a more time efficient, spatio-temporally finer resolved, and better standardized monitoring method. We base this test on our ongoing transplant experiment that since 2016 exposes 40 m2 of alpine plant communities to climate warming and 40 m2 of sub-alpine plant communities to climate cooling.
