Table 2. Frequency, plant traits database (from different sources) and landscape metrics measured in the field on 46 1 m × 1 m plots.

CA is the total cover in cm2. Standard deviation (±) are reported only for metrics which can be computed for every patch. Definitions, abbreviations and units of measurement of the landscape metrics are reported in Table 1. See Fig. 5 for abbreviations of species.
