    Ecological Intensification of Oregon Hazelnut Orchards: Restoring Native Plant Communities in Shared Ecosystems
    (University of Oregon, 2024-08-07) Lane-Massee, Marissa; Hallett, Lauren
    The rapidly expanding Oregon hazelnut industry offers a unique opportunity for restoring ecosystem services to private lands that were historically oak-prairie dominated habitats. With typical orchard management consisting of bare-soil orchard floors, ecological intensification through the use of native conservation cover may directly benefit farmers and their operations, saving time and money spent on land management. With the hazelnut industry currently investing resources into young orchards, soil management with cover crops has become a contentious point of research. Looking towards the future, understanding how cover crops can be tailored towards an expanding and aging Oregon hazelnut industry is imperative. Here, I study the feasibility of large-scale native conservation cover implementation in a mature orchard, with measurements of compatibility to orchard management practices and desirable ecosystem services that farmers can directly utilize. My results show that native conservation cover can successfully suppress orchard weeds, align with important pest management timeframes, facilitate hazelnut pickup during wet harvest years, reduce chemical and mechanical inputs, and while not having a significant effect on soil moisture, significantly reducing soil temperature during summer months. This study demonstrates the feasibility and compatibility for native conservation cover to be used in commercial hazelnut systems, and the capacity at which native conservation cover directly benefits the farmer and agroecosystem alike.
