Native vs. non-native plants -- an insect's perspective
We studied the abundance and diversity of insect species supported by 56 native and non-native tree species in four large scale common gardens designed to simulate a suburban yard. While non-native plants consistently supported fewer and less diverse insect communities, the effect is most pronounced for non-native plants without a local native congener (eg. a relative in the same genus).
