Data set: The cumulative impacts of droughts and N deposition on Norway spruce (Picea abies) in Switzerland based on 38 years of forest monitoring

This data set provides mortality data of Norway Spruce (Picea abies) from long-term forest obseravtion plots in Switzerland. The data set includes data from the start of the Intercantonal Forest Observation Program in Switzerland in 1984 until 2022. Data and models are used for the paper by Tresch et al. 2022: The cumulative impacts of climate change induced droughts and N deposition on the decline of Norway spruce (Picea abies) in Switzerland based on 38 years of forest monitoring.R codes can be found in the GitHub repository:https://github.com/treschsimon/Tresch_et_al_spruce_paper_R_code
