Abstract:
This dataset contains information from a tree census on the plots of the interdisciplinary research training group 'RTG2300: Enrichment of European beech forests with conifers'. The tree cesus was carried out during winter 2017/2018 using a Field-Map system (software Version 5x; IFER - Monitoring and Mapping Solutions, Ltd.; Prague; Czech Republic). All living and dead trees with a diameter greater or equal than 7.0 cm were recorded in the 0.25 ha plots (https://doi.pangaea.de/10.1594/PANGAEA.923125) and in a ten meter buffer zone surrounding the plot border. Tree coordinates relative to the plot center were recorded with a laser range finder with an integrated electronic compass (TruPulse Laser 360 R, Laser Technology Inc, Centennial, USA). Tree diameters were measured with a diameter tape preferentially at 1.3 m height. If a diameter measurement at 1.3 m was not possible, the alternative height of the diameter measurement was recorded. Tree species, tree vitality (dead or alive) and tree condition ('normal', 'snag', 'hung_up', 'sloping', 'thrown', 'stump') of each tree and heights of snags were recorded.

Comment:
The x- and y- coordinates of the trees specify differences between easting and northing coordinates of the trees relative to the plot center. The y-axis is pointing towards grid north (not magnetic or true north). The used reference system of the original easting and northing coordinates is 'ETRS89 / UTM zone 32N' (EPSG 25832). To obtain the original georeferenced coordinates of the trees, the relative coordinates in this dataset need to be added to the respective plot coordinates in dataset https://doi.pangaea.de/10.1594/PANGAEA.925226 (restricted access).
