  1. Simulating Regeneration Dynamics in Upland Oak Stands USDA Forest Service Southern Research Station Dr. David Loftis

  2. Regen for Excel is a simulation model that using rankings of expected postharvest performance to predict species composition of dominant and codominant trees twenty years following complete overstory removal USDA Forest Service Southern Research Station Dr. David Loftis

  3. USDA Forest Service Southern Research Station Dr. David Loftis

  4. Scenario 1: Midstory Present, No Yellow-Poplar Seed Source Density of Advance Seedling Reproduction by Species and Height Class (ft) prior to complete overstory removal

  5. Scenario 1: Midstory Present, No Yellow-Poplar Seed Source Species composition of dominant/codominant canopy trees twenty years following overwood removal

  6. Scenario 2: Midstory Present, Yellow-Poplar Seed Source Present Species composition of dominant/codominant canopy trees twenty years following overwood removal

  7. Scenario 3: No Midstory Present, Yellow-Poplar Seed Source Present Density of Advance Seedling Reproduction by Species and Height Class (ft) prior to complete overstory removal

  8. Scenario 3: No Midstory Present, Yellow-Poplar Seed Source Present Species composition of dominant/codominant canopy trees twenty years following overwood removal

  9. Scenario 4: Shade tolerant understory and midstory trees removed, Yellow-Poplar Seed Source Present Density of Advance Seedling Reproduction by Species and Height Class (ft) prior to complete overstory removal

  10. Scenario 4: Shade tolerant understory and midstory trees removed, Yellow-Poplar Seed Source Present Species composition of dominant/codominant canopy trees twenty years following overwood removal

  11. Simulating Regeneration Dynamics in Upland Oak Stands • Simulations underscore: • Importance of having competitive advance oak reproduction present prior to final overstory removal • Role of silvicultural treatments in controlling competing vegetation and enhancing the competitive position of oak reproduction USDA Forest Service Southern Research Station Dr. David Loftis
