Sample plot inventory data form the Parc Naturel du Jorat

The Jorat is one of the largest continously forested areas in the Swiss Plateau. On a forested area of 778 ha, the Parc Naturel du Jorat (PNJ), a periurban parc, has been established in 2022. To document the initial state of the forest within the perimeter of the PNJ, a sample plot inventory (SPI) was carried out on 132 sample plots (SP) in winter 2021/22. This dataset contains results from this sample plot inventory. It consists of the following files:

• results_trees.csv: Results for or living and dead trees.
• results_regeneration.csv: Results for trees with DBH < 7.0 cm, assessed in three height classes.
• results_lying_deadwood.csv: Results for lying deadwood, assessed no three line transects
• results_trems.csv: Results for occurence of tree related microhabitats (TreMs)
• results_habitat_trees.csv: Results for occurence / densities of trees carrying at least one TreM or with a DBH >= 80 for living trees or >= 36 cm for dead trees respectively.
• lookup.csv: Contains lookup tables which describe the respective results in-depth.
• data_description.pdf: Briefly describes the datasets mentioned above.
