Local and landscape drivers of butterfly richness and abundance in a human-dominated area

Our study also allowed to formulate management guidelines of specific habitats. Accordingly, meadows should be managed by reducing the number of cuts, while wide herbaceous margins, characterised by a high grass layer rich in dicots, should be maintained in arable lands. To avoid a barrier effect and to guarantee the presence of a well-developed shrub layer, which provides high nectar resources, it is also necessary to avoid an excessive growth in hedgerows height. Results evidence that the adoption of these management guidelines and of a proper landscape planning strategy, can lead to play an important role in butterfly conservation even within human dominated areas.
