Table 1 Location of study sites in Germany and their site characteristics. Mean annual volume increment of oaks is averaged for the period 0–100 years and determined with yield tables. Ecoregions (German ‘Wuchsgebiete’) follow the classification of the German Society of Forest Site Classification and Forest Growth (modified from Gauer and Aldinger 2005)
Sites | Location (name of the nearest town and state) | Ecoregion | Elevation m a.s.l. | Mean annual temp. (°C) | Mean annual rainfall (mm) | Soil types | Mean annual oak volume increment (m3 ha−1 year−1) |
