Hulme et al. (1) question the conclusions of our research on the impact of non-native plants on British plant diversity (2). We clearly state that “some non-native species become common in some locations, and thereby alter the local flora, and there may be local implications for conservation” (2), which seems to be Hulme et al.’s (1) main point, but we found “no evidence that non-native species drive such changes at a national scale or that they do so any more than native species” (2). Management may be required to remove non-native plant …
