NegBinMallardData.txt - Contains input data for the negative binomial regression results reported in the paper. Used as input to the Limdep file NegBinMallardRegression.lim. The file is comma delimited and contains 53 columns and 2714 rows. The columns correspond to the variables listed below, and each row corresponds to an observation, i.e., a unique route stop-year combination. -- TABLE: Please see in attached file. -- To make sure the file was downloaded properly, compare the column sums to the following figures: -- TABLE: Please see in attached file. -- BBSLand.csv - Contains the amount of each land use type near all BBS route-stops in the Central Valley of California. The file is comma delimited and contains 10 columns and 819 rows. The columns correspond to the variables listed below, and each row corresponds to an individual route-stop in the Central Valley of California. -- TABLE: Please see in attached file. -- To make sure the file was downloaded properly, compare the column sums to the following figures: -- TABLE: Please see in attached file. -- betasFIXEDC.csv - Contains 500 draws from the multivariate normal sampling distribution of beta, including only the most important land use variables (orchards, orchards^2, wetlands, wetlands^2, rice, rice^2, and wetlands*rice), as estimated using the data in NegBinMallardData.txt and the Limdep file NegBinMallardRegression.lim. The results presented in the paper can be reproduced using this file. betasFIXEDP.csv - Contains 500 draws from the multivariate normal sampling distribution of beta, including all land use variables, as estimated using the data in NegBinMallardData.txt and the Limdep file NegBinMallardRegression.lim. The results presented in the paper can be reproduced using this file. NegBinBeta.csv - Contains the estimated values for beta that result from using the data in NegBinMallardData.txt and the Limdep file NegBinMallardRegression.lim. NegBinCovBeta.csv - Contains the estimated variance-covariance matrix for the sampling distribution of beta that results from using the data in NegBinMallardData.txt and the Limdep file NegBinMallardRegression.lim. ObsCounts.csv - Contains the observed counts of mallards at all BBS route-stops in the Central Valley of California between 1997-2001. NegBinMallardRegression.lim - The Limdep file used to execute the negative binomial count regression model. BBSmax.m - The main Matlab file used to execute the optimization model and comparison scenarios. All remaining *.m files are subroutines of BBSmax.m. <b>Instructions</b> To reproduce the results presented in the paper, follow these steps: 1. Save all files in a single directory. <br> 2. In the "NegBinMallardRegression.lim," "BBSmax.m," and "WriteBBSmaxOut.m" files, replace all occurrences of [directory] with the name of the directory in which you saved the files. <br> 3. Execute the "NegBinMallardRegression.lim" file using Limdep version 7.0. Note: This step is only needed if you want to verify the regression results reported in the paper, or to try alternative versions of the regression model. <br> 4. Execute the "BBSmax.m" file using Matlab version 6.5. This will produce the following output file: BBSmaxOut.txt - will contain the main results from the model. The summary results, which are reported in the paper in Table 4, are at the top of the file. Secondary results are given in four columns below the summary results. The four columns contain: (1) "rs," the route-stop number, (2) "conag," the amount of land that could be converted from agriculture to wetlands at the route-stop, (2) "rSTAR," the optimal amount of restoration to undertake at the route stop, and (4) "muSTAR," the average number of mallards expected to be counted at the route stop if the optimal amount of restoration is completed there. <br>

<b>复现指南</b>
如需复现本文报告的研究结果，请按以下步骤操作：
1. 将所有文件保存至同一目录。
2. 在`NegBinMallardRegression.lim`、`BBSmax.m`与`WriteBBSmaxOut.m`文件中，将所有`[directory]`替换为你保存文件的目录名称。
3. 使用Limdep 7.0版本执行`NegBinMallardRegression.lim`文件。注：仅当你需要验证本文报告的回归结果，或尝试构建回归模型的变体版本时，才需要执行此步骤。
4. 使用Matlab 6.5版本执行`BBSmax.m`文件，将生成如下输出文件：
- BBSmaxOut.txt：包含模型的核心结果。本文表4中报告的汇总结果位于文件顶部，汇总结果下方附带四列次要结果：
1. `rs`：样线-停歇点编号
2. `conag`：该样线-停歇点处可从农用地转换为湿地的土地面积
3. `rSTAR`：该样线-停歇点处最优的生态修复规模
4. `muSTAR`：若完成该最优规模的生态修复，该样线-停歇点处预期观测到的绿头鸭平均数量
