SCORE ProgramSouth Carolina Oyster Restoration and Enhancement program

• Began in 2000

• ~10,000 Volunteers since

2000

• ~30,000 Volunteer Hours

since 2000

• ~38,200 SCORE Bags

• ~25,500 bushels of shell

• ~573 tons of Shell

• 10 yrs. = ~1.2 acre of oyster

habitat

• Developed a successful

model of volunteer-based

oyster restoration

• Create fish habitat• 1 acre of oyster reef

• Large scale plantings of shell aggregate• Seeded shell (spat collection bags from docks)

• Protect 1-2 acres of salt marsh

• Engage dock-owners with volunteer opportunities• 800 volunteer hours

• Outreach/educational opportunities• Spat collection bag creation• Bag deployment

• Build on Bears Bluff’s reputation of community engagement in the area

• Public outreach events• Wadmalaw Island Land Planning Committee Mtg.• Johns Island Council Mtg.• Seabrook Island Natural History Group

• Word of mouth• “Bumpsy”

Volunteer Opportunities• Shell recycling• Make bags to hang from docks

• Community bagging events• Hang bags from docks• Deploy seeded shell to shoreline

Spat Collection Bags• ~8ft. Long• 8 “bubbles”/bag

• ~0.75m2/bag coverage of shoreline

• ~12 shell/bubble• Maximizes surface area of individual shells for

collection of spat
