Bee Richness and Abundance in New York City Urban Gardens

Urban Farm DB summary

Bees were surveyed over 4 years in community gardens in heavily developed neighborhoods of the Bronx and East Harlem, New York City, yielding 1,145 individuals from 54 species (13% of recorded New York State bee fauna). Soil-nesting individuals were relatively rare (25%), possibly due to a lack of suitable nesting soils, and parasitic species were scarce (5.6% of species, 2.6% of individuals); exotic species were common, comprising 27% of individuals and 19% of species collected. Compared with other bee faunal surveys in New York and New Jersey, including Central Park and Prospect Park, bee richness in these urban gardens was reduced and the species composition was biased toward exotic and cavity-nesting bees, though the gardens still supported a diverse bee assemblage despite their small size and location within highly urbanized areas.
