Table 1.

Repeated Measurement ANOVA table for the effect of Invasion Status (Control plots vs. Invaded plots) and Year (sampling year 2020 vs. 2021) on Native species total cover, native species richness and native species diversity expressed as H’, provided for each Natura 2000 habitat. N2000 habitat codes: 1240 = vegetated sea cliffs of the Mediterranean coasts with endemic Limonium spp., 1430 = Halo-nitrophilous scrubs (Pegano-Salsoletea) and 5320 = Low formations of Euphorbia close to cliffs. numDF: numerator degree of freedom; denDF: denominator degree of freedom. Significance codes: p value < 0.001 ‘***’; p value < 0.01 ‘**’; p value < 0.05 ‘*’, p value < 0.10 ‘˙’.
