AbstractVineyards may be biodiversity-rich habitats, as areas between vine rows could host a diverse flora of local species or cover crops. Vegetation cover within vineyards provides important ecosystem services, such as soil erosion mitigation and the provision of habitat and food resources for pollinating insects and natural enemies of pests. However, dense vegetation cover could also lead to increased water and nutrient competition between vines and weeds. Frequent tilling or the use of herbicides for the eradication of vegetation cover are associated with ecosystem disservices, such as very high rates of erosion, degradation of soil structure and fertility, contamination of groundwater and high levels of agricultural inputs, such as pesticides. In the BiodivERsA project VineDivers, we analyze the effects of three different management intensities (bare soil, permanent or temporary vegetation cover) on above- and below-ground biodiversity and the associated ecosystem services across Europe. We established four plots within each vineyard of high, medium and low intensity management. In this paper, we present the results of the plant diversity survey. Up to now, we recorded plant biomass and diversity in 81 Austrian, French, Romanian and Spanish vineyards at least two times a year. Species diversity was significantly higher in vineyards with permanent or temporary vegetation cover compared to vineyards with bare soil. In Austria, diversity in vineyards with permanent vegetation cover was not significantly higher than in vineyards with temporary vegetation cover. We will discuss the results of the vegetation survey in view of related ecosystem services in vineyards.
