Variation in pollinator service to restored experimental wildflower patches differing in species richness.

ABSTRACT- Individual species of pollinators vary in response to landscape patchiness. This has implications for ecological restoration projects, which must reinstate adequate levels of pollination for the target plant community to persist. Here we investigate how pollinator service is affected by the planting design in the ecological restoration of a woodland wildflower community. Keeping patch size constant, we compared three planting treatments: 1) monocultures, 2) mixes of 3 plant species, and 3) mixes of 6 plant species. We recorded pollinator activity across all treatments and obtained voucher specimens, which were identified and sampled for pollen. Monocultures flowered copiously for a short time, whereas mixed plots offered fewer floral resources but for a longer time. As a consequence, patterns of insect visitation and pollen movement were markedly different across the treatments. We discuss the practical implications for ecological restoration.
