Increasing parameter accuracy of an agriculturally focused, spatially-explicit bee abundance model


September 2014 - May 2019


The increasing risk of relying on honeybees for crop pollination has led to growing interest in native bees as a potential alternative to ensure successful production. This research is examining the use of powerline easements for nesting and foraging by native bees to understand relationships of landscape setting to native bee diversity.
