Bird-Friendly BMP’s for Bottomland Forest in the Carolinas Birds and People on Common Ground
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 state Feathered 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
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
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
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
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
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
Bird survey Hooded Warbler
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
