Costs of restoring and preserving wetlands vary across the United States

Map showing county-level estimates of the cost per acre of restoring and preserving a new wetland

USDA’s costs of restoring and preserving new wetlands across the contiguous United States range from about $170 to $6,100 per acre, with some of the lowest costs in western North Dakota and eastern Montana and the highest in major corn-producing areas and western Washington and Oregon. To analyze conservation program expenditures, ERS researchers generated county-level estimates of wetland costs for each of the major wetland regions as designated by USDA’s Natural Resources Conservation Service (outlined in black in the map), using primarily NRCS Wetland Reserve Program contract data. Variations in costs are driven by differences in land values and the complexity of restoring hydrology and wetland ecosystems. Information about how the costs of restoring and preserving wetlands vary spatially (together with the relative benefits) can inform wetland targeting policies within States/regions and across the U.S. This map is found in the ERS report, Targeting Investments to Cost Effectively Restore and Protect Wetland Ecosystems: Some Economic Insights, ERR-183, February 2015.
