Dataset Abstract

This dataset contains the height, diameter and growth corresponding to the last 5 years from all juveniles, which were found in 16 subplots of 1m x1m, located in the central quadrant (in the upper half) of the main plot.

Dataset Design

Firstly, the regeneration plot (4m x4 m) was delimited in the central quadrant (in the upper half) of the main plot. After, the regeneration plot (4m x4 m) was subdivided in 16 subplots (1m x 1m). Within each 1x1m subplot, the juveniles from the focal tree species were identified and measured their height, diameter and growth corresponding to the last 5 years.

Spatial Extent

Spain

Taxonomic Extent

The focal tree species in Spain are Quercus ilex, Quercus faginea, Pinus sylvestris, Pinus nigra.

Measurement Circumstances

strong drought in 2012.
