Pollinator Communities of Planted and Feral Pyrus calleryana

Pyrus calleryana was intentionally introduced to North America from east Asia in the early 1900s as rootstock for edible pear tree, communis. It identified an ideal decorative, agricultural, and horticultural tree because of its small stature, spring flowering, fire blight resistance inoffensive fruits. P. escaped cultivation is now considered invasive species, typically found on roadsides, prairies, fields. The aim this study characterize pollinator community diversity planted feral trees, well it compares expected communities derived research-grade iNaturalist observations. Pollinators were collected by hand trees April 2018–2022. A total 14 taxa insect flowers, with similar levels Apis mellifera Andrena spp. most common observed. sampled did not differ generated using data either or calleryana.
