Wild Bees of New York

Pollination is a valuable ecosystem service

Pollination is a valuable service provided by both managed bees (primarily honey bees, Apis mellifera) and wild, native bees. Bee pollination is essential for the production of fruits, nuts, vegetables, spices, stimulants (such as coffee), and edible oils (such as sunflower and canola). Estimates of the economic contribution of pollination vary widely, but two recent studies give us a sense of the magnitude of the contribution pollinators make to the global and national economy. Gallai et al. (2009) estimated that the contribution of pollination to the global economy was approximately $170 billion annually, and Calderone (2012), based on data for the US alone, estimated that pollination contributes over $15 billion/year to the US economy. In New York, important pollinator-dependent crops include apple ($250 million/year), squash and pumpkin ($74 million/year), tomatoes ($47 million/year), strawberries ($7 million/year), cherries ($3 million/year), and pears ($2.5 million/year) (economic data from New York State Department of Agriculture and Markets; www.agriculture.ny.gov). Many of New York’s most high value fruits are entirely dependent on pollinators for successful production.

Why study wild pollinators in New York State?

  • New York State is home to a surprisingly diverse fauna of wild bees that contribute to apple pollination in NY.
    We have documented over 110 wild bee species visiting apple blossoms in surveys of NY apple orchards from Lake Ontario to the Hudson Valley (Russo et al. 2015). We have shown that wild bees are numerically abundant across orchard varying in size and management (Russo et al. 2015), that wild bees are highly effective pollinators on a per-visit basis (Park et al. 2015), and that wild bee diversity and abundance are correlated with apple fruit and seed set (Blitzer et al., in prep.). Apples are not the only crop that benefits from wild pollinators. Strawberries, pears, cherries, tomatoes and cucurbit crops are benefiting from a diverse wild pollinator fauna as well.
     
  • Documenting the diversity of wild bees in New York is an important part of promoting the health and stability of pollinator populations. To that end, we have been developing a complete list of New York’s wild bees. Our goal is to accurately document what species occur in New York, which bee species are native and which non-native, which are declining or rare, and as much information about the natural history, nesting biology, floral preferences, social behaviors as possible.
