Production & Evaluation of Mid to Low Elevation Locally-grown Trees to Replace Imported Christmas Trees

The next phase of our Christmas tree efforts with include “Production & Evaluation of Mid-to-Low Elevation Locally-grown Trees”.  This project will demonstrate that conifer species can be grown at mid-to-low elevations and identify the species and cultivars that produce acceptable Christmas trees – in pots and in the ground.  Outplantings at different elevations will be done with collaborators.  This project will complement HFIA’s higher elevation Douglas fir plantings to help expand a fledgling local Christmas tree industry by identifying a variety of species to replace imported trees at different elevations.  Leyland Cypress (xCupressocyparis leylandii), Norfolk or Cooke Island Pine (Araucaria sp.), Monterey Pine (Pinus radiata) and Cypress species (Cupressus spp) are potential species.  Our goal is that this effort leads to reduced imported container stock; reduced alien species introductions; and reduced workload of State Agricultural inspectors.  Funders for this phase include State of Hawai‘i Department of Agriculture (HDOA), US Department of Agriculture (USDA)-Agricultural Marketing Service, and County of Hawaii Department of Research & Development.
