Structure of bee communities in marginal lands of the Puget Sound, USA

Wild bee communities in urban ecosystems are often challenged by habitat fragmentation and low floral diversity. In such settings, marginal land surrounding airports or in power line corridors may support bees, even with small habitat patches. However, temporal surveys of wild bees are lacking for many urban areas such as the Puget Sound region of western Washington State, USA. Here, we conducted wild bee surveys at three peri-urban sites in the Puget Sound over 7 years. Specifically, a standardized protocol was used to sample wild bee communities monthly from April to October at two sites associated with airports and one site in a power line corridor. In total, our surveys collected 25,441 specimens representing 118 confirmed species within 24 genera, with individual subsites having between 15 and 35 species in any year. The Halictidae represented the most individuals collected, with 47% of specimens. By genus, Lasioglossum was the most speciose (n = 21), with Bombus, Osmia, and Andren..., , # Data from: Structure of bee communities in marginal lands of the Puget Sound, USA

## Description of the data and file structure

Bees were collected from marginal lands of the Puget Sound region in western WA (USA) from 2014-2020. Trap and net collection methods were used at 3 sites: Port of Seattle (POS), Boeing Paine Field (BPF), and Seattle City Light (SCL) power line corridor. All 25,000 bee specimens collected have been identified to genus, and 98.3% have been identified to the species level.
