Influence of Mycorrhizal Inoculation on Ponderosa Pine Seedlings Outplanted on Wildfire Sites in Northeast Oregon and Washington

Hot-planted, 4-month-old container ponderosa pine (Pinus ponderosa Lawson & C. Lawson) seedlings were planted on five sites affected by wildfire in northeast Oregon and Washington. Seedlings were planted with or without mycorrhizal treatments. Survival exceeded 90 percent regardless of site or treatment after two growing seasons. Mycorrhizal inoculation at the nursery or in the field before outplanting did not improve seedling survival or growth. Only one test site, likely the most severely burned site, averaged better seedling growth with mycorrhizal inoculation compared with the noninoculated control treatment. Height and stem diameter growth differed among sites, likely due to differences in vegetation management strategies and subsequent competing vegetation levels. This paper was presented at the Joint annual meeting of the Western Forestry and Conservation Nursery Association and the Pacific Northwest Reforestation Council (Corvallis, OR, October 11–12, 2017).
