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

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

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

Hardwood thinning
Ideally we want to thin down to 60-70% canopy closureTree selection can be done to leave better species composition for economics or mast production

95% Canopy Closure

60% Canopy Closure

60% Canopy Closure

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.

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

Hurricane Damage

Ideal Silver Bluff Location
Since we get to choose where we put our thickets, we can pick places that naturally grow the types of understory we want!
![Page 22: Bird-Friendly BMP’s for Bottomland Forest in the Carolinas Birds and People on Common Ground.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649c885503460f9494159c/html5/thumbnails/22.jpg)
Ideal Four Holes Swamp Location
Ironwood, Sweet Gum, Palmetto, Loblolly Pine, Water and Swamp Chestnut Oaks, Green Ash, American Elm, Hawthorne, Switch Cane, and Persimmon
Higher… less flooded areas
