Forest inventory data of beech for the development of individual-tree mortality models from strict forests reserves in Switzerland, Germany and Ukraine.
The data package provides the files CH_reduced: inventory data of the reduced dataset from Switzerland that was used to assess the influence of additional environmental and stand characteristics on beech mortality CH: inventory data from strict forest reserves in Switzerland DE: inventory data from strict forest reserves in Germany UA: inventory data from a primeval beech forest in Ukraine
A set of three consecutive inventories was used to generate records for the calibration of mortality models based on trees that were alive in the first and second inventory and either dead or alive in the third inventory. Diameter at breast height: dbh (mm) Annual relative basal area increment: relBAI (), calculated based on the first and the second dbh measurement as the compound annual growth rate of the trees basal area (Bigler and Bugmann 2004) Status of the tree: y, 0 = alive, 1 = dead Length of the mortality period: dt (years)
Additional environmental and stand characteristics were derived for the reduced Swiss dataset. Note the varying seasonal level of the covariates considering the entire year, the growing season from April to September (G) and the winter month January to March (W). All climatic covariates were calculated for both the ‘growth’ (2) and the ‘mortality’ period (3). The stand covariates were derived for the second inventory of each record (2).
Mean diameter at breast height: dbh.mean.2 (mm) Interquartile range of diameter at breast height: dbh.IQR.2 (mm) Median diameter at breast height: dbh.median.2 (mm) Basal area per hectare: BA.2 (m2 ha-1) Number of trees per hectare: N.2 (ha-1) pH-value: pH () Available water capacity in the soil: AWC (mm) Mean annual precipitation sum: P.2, P.3 (mm) Mean precipitation sum during growing season: PG.2, PG.3 (mm) Mean annual air temperature: mT.2, mT.3 (°C) Mean air temperature during growing season: mTG.2, mTG.3 (°C) Mean air temperature during winter months: mTW.2, mTW.3 (°C) Mean growing degree-days: GDD.2, GDD.3 () Mean number of months during growing season with water deficit: mDEFdurG.2, mDEFdurG.3 () Mean annual maximum water deficit: mDEFmax.2, mDEFmax.3 (mm) Overall maximum of the annual maximum water deficit: maxDEFmax.2, maxDEFmax.3 (mm) Mean of cumulative water deficit during growing season: mDEFcumG.2, mDEFcumG.3 (mm) Overall maximum of cumulative water deficitduring growing season: maxDEFcumG.2, maxDEFcumG.3 (mm) Percentage of years with at least one month water deficit: percDEF.2, percDEF.3 (%)
