Associations Between Pollinators and Native Plants in the Willamette Valley – Aaron Anderson , Oregon State University

03nativeplantsAaron Anderson will provide recommendations of native plants to include in your own garden to support diverse bee communities, including rare bees and bees that are considered ‘vulnerable’ on the IUCN Red List of Endangered Species.

Since 2017, Aaron has been managing a large-scale field trial of 23 native Willamette Valley plants, to document the insect community associated with each species. He has also been monitoring the insect community on four species of non-native ornamental plants that are commonly found in gardens, and that are touted for their benefits to pollinators. In 2018, Aaron surveyed gardeners to find out how they rank the aesthetic beauty of his 27 study plants, all in an effort to find the ‘sweet spot’ of plant species that are attractive to pollinators, as well as to gardeners. This talk will present initial findings from Aaron’s study.

Aaron is pursuing his Ph.D. in Horticulture at Oregon State University, under the direction of Gail Langellotto. A Portland native, Aaron received his B.S. in biology at Cornell University. After graduation, he worked on native plant restoration projects in the San Francisco Bay area, took courses in Geographical Information Systems, and worked in an entomology laboratory at Colorado State University.
