Tree height is estimated using laser rangefinder model "TruPulse 200" manufactured by "Laser Technology" company. Canopy length is measured using a measuring tape held by two people standing in the east-west direction, either north-south. Browsing height is estimated using measuring tape from the ground up to the high point of browsed branches. The lowest leaf height is measured using measuring tape from the ground up to the first low leaf. The trunk perimeter is measured with a soft measuring tape at the height of the tree tag, which is placed in a fixed position on the trunk. The greenes index is detected by taking NDVI photo of the tree from south position, using TETRACAM MULTISPECTRAL camera. The photos are analized by PIXELWRENCH2 softwrae. Photograph of the tree is taken from a southern position including a 1-meter scale stick and a color palette for calibration. ImageJ software is used for analyzing the RGB channels (data not supplied). The foliage, flowers, and pods are visually rated on a scale of 0 to 5 (low-high).

The dataset contains monthly growth of the dominant tree species (Picea abies and Fagus sylvatica) between 1996 and 2019 in three intensive plots of LTER Zöbelboden based on weekly dendrometer measurements and forest inventory data.

Long-term forest inventory and aboveground tree biomass data from LTER Zöbelboden Austria (2003-2019). The dataset contains forest inventory parameter (tree species, tree vitality status, diameter at breast height, tree height) as well as stem, branch, foliage/needle and total aboveground biomass of the trees within the three intensive plots of LTER Zöbelboden. The forest inventories were conducted in 2003, 2007, 2012 and 2014 (IP1), 2003, 2007, 2014 and 2019 (IP2) and 2012, 2014 and 2019.

Long-term forest inventory and aboveground tree biomass data from LTER Zöbelboden Austria (1993-2019). The dataset contains the forest inventory parameter (tree species, tree vitality status, diameter at breast height, tree height) as well as stem, branch, foliage/needle and total aboveground biomass of the trees within the permanent inventory plots covering the LTER Zöbelboden. The forest inventories were conducted in 1993, 2005, 2010, 2014 and 2019.

Data on 51 permanant observation pine stands established according to the methodology of Forest monitoring level I programme are presented. Investigations are carried out since the 1989. Presented data: dendrometric parameters, condition, defoliation, tree ring width series, FAR/LAI, primary productivity, dead wood, meteorology, soil chemistry.
