This study evaluates the infuence of summer fowering cover crops and landscape diversity on the abundance and diversity of vineyard bee populations. We showed that diversity and abundance of wild bees were increased on the fowering cover crop, but were unaffected by changes in landscape diversity. These fndings indicate that summer fowering cover crops can be used to support wild bees and this could be a useful strategy for grape growers interested in pollinator conservation as part of a broader farmscape sustainability agenda.
