Collected Evidence: Collected Evidence: Establish “green infrastructure” in urban areas One study evaluated the effects of establishing “green infrastructure in urban areas on butterflies and moths. This study was in Taiwan. COMMUNITY RESPONSE (1 STUDY) Richness/diversity (1 study): One replicated, site comparison study in Taiwan found that green roofs had a lower species richness of butterflies than urban parks. POPULATION RESPONSE (1 STUDY) Abundance (1 study): One replicated, site comparison study in Taiwan found that green roofs had a lower abundance of butterflies than urban parks, but the abundance was higher on older green roofs with more nectar plant species in a larger area.
