A data set for pollinator diversity and their interactions with plants in the Pacific Northwest.

Pollinator populations have declined substantially in recent years. The resulting loss in pollination services has both ecological and economic consequences including reductions in plant diversity and crop production and lower food security. Data sets that identify pollinators and their plant hosts are of utmost importance in order to understand the main causes of pollinator declines. Here we present a data set, which contains 67,954 individual pollinator records. The data has been collected across the Pacific Northwest, primarily focused in British Columbia (Canada), with 182 individual sites over 11 years, between 2005 and 2017. This data set comprises multiple studies that aimed to collect information on pollinator abundance, diversity and their interactions with plants. Overall, the data set includes 937 morphospecies (of which 482 were identified to species) of pollinators across 105 families, including data for bees, wasps, butterflies, moths and flies. We also present information on the interactions of these species, with 473 species of plants. This data set is released for non-commercial use only.
