Estimating the Cost of Wetland Restoration in the Prairie Pothole Region R. L. Bernknopf, C. D. Shapiro, D. R. Soller, W. S. Moy U. S. GEOLOGICAL SURVEY 922 National Center Reston, Virginia 22092 Abstract Decisions on wetlands preservation, creation, and restoration need to address a number of economic and social factors to ensure an optimal use of resources. Economic literature includes models for examining the benefits and costs associated with preservation of wetlands in the prairie wetlands pothole region. this analysis broadens an existing economic model for prairie wetlands to include restoration costs. A statistical model was developed to estimate wetland restoration costs in portion of the prairie pothole region using information that can be derived from existing regional geologic and topographic maps. The hypothesis tested is that physical science attributes influence the cost of wetland restoration. The results from the statistical model support the hypothesis that two physical science variables, average slope and soil permeability, influence wetland restoration costs in the prairie pothole region. Introduction During the next decade, many complex land-use decisions will be made in order to implement the President's stated goal of "no net loss" of wetlands. Decision-makers will have to consider physical and economic factors in deciding which wetland areas should be maintained, and which geographic areas are the best candidates for either wetland restoration or creation. Federal, State, and local government agencies such as the U.S. Fish and Wildlife Service (FWS), the U.S. Army Corps of Engineers (COE), and the Agricultural Stabilization and Conservation Service (ASCS) restore wetlands from active and idle farmland and ranchland. In the past, significant amounts of wetland areas were drained by farmers and ranchers in order to create additional cropland. President Bush stated on June 1, 1992, that during the past four years, the national has "... restored or protected more than one-half million acres a year of important wetlands." (Bush, 1992). Gathering the data necessary to undertake a site-by-site analysis of wetland restoration or creation costs is both time consuming and expensive. The model developed in this paper takes an alternative approach to estimating the cost of wetland restoration. Cost estimates of wetland restoration in a part of the prairie pothole region in northeastern South Dakota are estimated statistically using existing regional earth science information. This technique is designed to assist decision- makers examine many candidate areas simultaneously in order to choose where to 25
