CSV file containing data used in our analysis including the following six tables:
1. Primary Matrix: includes the plot (rows) x species (columns) matrix used for our NMS analysis.
2. Secondary Matrix: includes our plot (rows) x site factors (columns) used in our joint-plots. MAP= mean annual precipitation, MAT=mean annual temperature.
3. NMS Scores: worksheet includes the output from our NMS analysis for plots (rows) and the three axis (columns).
4. Species Abundance Data: measured abundance by species by plot. Columns include: plot, species (using USDA Plants Database codes), Presence (1=yes; 0=no), Treated (Yes/No), Herbivory (Yes/No) and Group (treatment combinations).
5. Species Height Data: Height (measured and log transformed) by species by plot.Species names use USDA Plants Database codes.
6. Plot Summaries: plot richness, diversity, and total shrub abundance (sum of all species frequencies) by treatment.

The table shoes the results of the indicator species analysis for the full species pool of the examined forests. Species without IndVal (Column C) had no significant preference. Codes for different forest types inluded in columns G-H.
In Column A we show the phytosociological behavior of the species based on Borhidi 1995.
Data were collected from 80 pure silver birch stands growing on post-agricultural lands in the province of Mazowieckie in central Poland. Individual sample plots were located within silver birch stands that spontaneously and naturally regenerated, with the age ranging from 3–19 years. Tree heights (H) and the diameters at the breast heights (D) were measured for a random sample of trees using the VERTEX IV hypsometer (Häglofs, Sweden). 3,577 trees were measured in total.
Data consists also the quadratic mean diameter at the breast height (Dg, cm) and basal area (BA, square meter per hectare) for each plot.
