Thirty years of ecological research at the Gran Sasso d'Italia LTER site: climate change in action
Since 1986, vegetation monitoring of alpine plant communities has been performed at the Gran Sasso d'Italia LTER site (https://deims.org/c0738b00-854c-418f-8d4f-69b03486e9fd) in the Central Apennines, through phytosociological relevés and abundance and coverage estimation of the vascular flora...

Since 1986, vegetation monitoring of alpine plant communities has been performed at the Gran Sasso d'Italia LTER site (https://deims.org/c0738b00-854c-418f-8d4f-69b03486e9fd) in the Central Apennines, through phytosociological relevés and abundance and coverage estimation of the vascular flora at fine scale.
