Dataset Abstract

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 fertilization. Phosphorous was applied once in April 2014, Insecticides and fungicides were sprayed monthly (and in May and June of each year bi-weekly) from April 2014 on. Control and phosphorous plots were sprayed with an equal amount of water.

Dataset Design

The herbivory assessments were conducted at the end of the main growing season in September to quantify standing levels of leaf damage. The degree of foliar damage by insects, defined as the combined removal of photosynthetic tissue by leaf-chewing, mining and galling (and, if visible, sucking) insects, was estimated using percentage classes of herbivore damage. On each tree, seven leaves on three randomly selected branches from different parts of the canopy (= 21 leaves per tree) were visually inspected. Herbivory was quantified as the overall leaf damage caused by chewing, mining, galling and (if visible) sucking insects per leaf. We used predefined percentage classes (estimated as 0%, 75%). Values provided here are the means of each category (i.e. 0%, 2.5%, 15%, 37.5%, 62.5%, 87.5%). As additional data, the total number of leaves was estimated and the main damage type was recorded.

TAG
identifier for the tree; Datagroup description: Tree tags consist of 12 digits: The first 6 are the site plot name: _1_ site _2/3_ row, counting from North _4/5_ column, counting from west _6_ is the plot moved? Is it a quarter pot? The next 6 digits describe the tree individual _7/8_ type of individual (01 planned tree, 02 other tree than planted but in a given plot somewhere, 03 planned shrub, 04 other shrub within this plot) _9/10_ x grid position within plot, starting from southwest northwards _11/12 y grid position, starting from southwest eastwards
