How much does it cost to conserve good prairie? Conservation Practices Protection: Easements- 473,000 ac. = $723,600,000 to $892,750,000 Grasslands- Approximately 87,000 acres of grasslands and other uplands are protected on PINS and NWRs. A few thousand additional acres are protected on private preserves, conservation easements, state parks, and WMAs. Approximately 260,000 of grasslands and potential grasslands remain in the priority areas to be protected. Protecting 180,000 acres of grasslands will cost approximately $468,000,000 to $520,000,000.00. Estuarine marsh- Approximately 47,000 acres of estuarine are protected on PINS and NWRs. A few thousand additional acres are protected on private preserves, conservation easements, state parks, and WMAs. Approximately 95,000 of estuarine marsh and potential estuarine marsh remain in the priority areas to be protected. Protecting 95,000 acres of estuarine marsh will cost approximately $114,000,000 to $166,250,000.00. Palustrine marsh- Approximately 20,000 acres of palustrine marsh are protected on NWRs. A few thousand additional acres are protected on private preserves, conservation easements, state parks, and WMAs. Approximately 118,000 ac. of palustrine marsh and potential palustrine marsh remain in the priority areas to be protected. Protecting 118,000 acres of palustrine marsh will cost approximately $141,600,000 to $206,500,000.00. Management: Restoration and Enhancement- 186,871 to 269,347 ac. = $ 8,534,997 to $9,359,755/year.
