  1. Bird-Friendly BMP’s for Bottomland Forest in the Carolinas Birds and People on Common Ground

  2. Typical Hardwood Management Historically we’ve left as is… or done large harvests followed by natural regeneration

  3. Small Patch Clearcut 2-10 acres with <10% of entire bottomland in regenerative state Feathered edges necessary if thinning does not accompany clearing

  4. “String of Pearls”

  5. Spokes of a Wheel

  6. Example – Silver Bluff Audubon Center • 90 acre stand • Homogenous stand condition • 25 year old stand • Mature forest function– 95% canopy closure • Prescription • Regenerate 10% of stand using patch cut(s) • 15 year entry cycle • 135 year rotation

  7. Feathered edge of a small patch opening

  8. Brown-headed Cowbird Prolific! One female can Lay as many as 40 eggs a season In other birds nests! Nest parasites that grow larger And compete for adoptamom’s resources All things equal Thickets as far interior as possible

  9. Thicket example 1

  10. Thicket example 2

  11. Hardwoodthinning Ideally we want to thin down to 60-70% canopy closure Tree selection can be done to leave better species composition for economics or mast production

  12. 95% Canopy Closure

  13. 60% Canopy Closure

  14. 60% Canopy Closure

  15. Epicormic Branching Is a problem that can occur when too much sunlight is allowed into a stand. While epicormic branching can hinder log quality, we feel that a conservative thinning will close canopy quickly enough to avoid this concern.

  16. So how do we decide where? Often times it is best to mimic mother nature! Consider invasive species

  17. Tornado Damage

  18. Hurricane Damage

  19. Since we get to choose where we put our thickets, we can pick places that naturally grow the types of understory we want! Ideal Silver Bluff Location

  20. Ideal Four Holes Swamp Location Higher… less flooded areas Ironwood, Sweet Gum, Palmetto, Loblolly Pine, Water and Swamp Chestnut Oaks, Green Ash, American Elm, Hawthorne, Switch Cane, and Persimmon

  21. “Flippable” Ground Litter

  22. Bird survey Hooded Warbler

  23. Swainson’s Warbler 1989 post tornado this species was Prevalent on the S.B. Island and has since Moved on due to lack of habitat

  24. National Audubon is telling me to cut TREES??? And hunt DEER??? Brandon Heitkamp Resource Manager Silver Bluff Audubon Sanctuary 803-522-2299 Norman Brunswig Executive Director Audubon South Carolina 843-462-2150
