Dataset on functional traits of epigeic spiders from the pitfall traps in the 27 CSPs. The effects of species loss on ecosystems depend on the functional characteristics of the species, i.e. the functional diversity, in a community. However, how f...

In forests, the herbaceous understory vegetation plays an important role for ecosystem functioning as it represents a significant component of total aboveground productivity. In addition, the herb layer contributes to overall forest species richne...

To test the effect of diversity on leaf area index (LAI) we took hemispheric pictures in each CSP in early spring and in summer of 2012. Plots were divided into nine subplots and pictures of the canopy were taken in the center of each subplot, at...

The BEFmod experiment was established in 2014 on the VIP plots of site A and site B. In the last four rows of trees, five treatments (à 16 trees in 4 rows x 4 columns) were set up: control, no-weeding, insecticides, fungicides, phosphorous fertili...

Tree composition of three tree groups in the CSPs

To test the effect of diversity on stand productivity, in summer 2018 and 2012 we measure the diameter at breast height (DBH) of alI individuals with a DBH of at least 10 cm. In 2012, we also measured the height (parallel to the stem if the tree w...
