Abstract:
Wine growing areas are potentially characterized by a high biodiversity. Beside natural factors, management intensity plays a decisive role. The aim of the present study was to investigate the effect of three vineyard management intensities on plant diversity and the composition of plant species in Halbturn (Austria): (i) high management intensity with frequently tilled inter-rows, (ii) moderate management intensity with cover crops in every second row, (3) low management intensity with permanent vegetation cover. Vegetation was recorded (scale of Londo) in spring and summer in 21 vineyards on four 1 x 1 m plots in the inter-row and four 1 x 0.4 m plots in the row. In total, 56 species were found, mostly Asteraceae. Species number decreased with increasing management intensity: mean at low intensity 20 ± 2.29, at moderate density 19.33 ± 4.41, at high density 16.54 ± 2.29. Shannon index did not differ between the three management types. The impact of management intensity on the composition of species was clear. At high density annual R-strategists like Veronica persica and Capsella bursa-pastoris were significant indicator species. Three indicator species were identified for the inter-rows of moderate management intensity: perennial CSR-strategists Trifolium repens, Medicago varia, and C-strategist Vicia cracca. The perennial CR-strategists Lolium perenne and Taraxacum officinale showed high indicator values at low inter-row management intensity. Overall, it was confirmed that management intensity plays an important role for plant species diversity and composition.
