Millora 2.0: Redovisning av resultat för 2018–2020

Based on repeated surveys of the vascular plant flora in 120 hectar plots in the province of Scania, southern-most Sweden, and analyses based on species-specific traits and ecological indicator values, it is concluded that significant changes have taken place 2018–2020 but that they probably mostly reflect the effects of the extremely dry and hot summer of 2018. Species richness has increased significantly, both at the local and at the regional scale, and the flora has changed towards species with higher temperature demands and higher demands for light and management, but lower demands for water and nitrogen. Furthermore, short-lived species with ant-dispersed, rapidly germinating but long-persisting seeds and less dependent on insect pollination have been favoured
