2000
• ~30,000 Volunteer Hours
since 2000
• ~38,200 SCORE Bags
• ~25,500 bushels of shell

• 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
