Agricultural Water Security and Instream Flows for Endangered Species
研究加州索诺玛县濒危鲑鱼物种列入保护名单后， landowners 的土地利用和用水决策变化，发现葡萄园开发与水库建设减少，但夏季地下水或直接引水增加可能损害幼鱼生存所需的夏季流量。
We analyze the potential effects of listing threatened salmonid species on landowner behavior using parcel‐level data from Sonoma County, California. We estimate a bivariate probit model, representing the landowner's joint decision on land use and water management during the period 1973–2006, both before and after listing. Our results indicate that after listing, vineyard development with on‐site reservoirs became significantly less likely, particularly in upland watersheds with seasonal streams. This interseasonal shift from stored surface water in winter toward groundwater or direct diversion in summer may lead to negative unintended consequences on summer flows needed for juvenile fish survivorship.
