Wetlands: An Overview of Issues

[摘要] This report discusses policy topics that involve wetlands. The U.S. Fish and Wildlife Service released its most recent periodic survey of changes in wetland acreage nationwide in March 2006. Covering 1998 to 2004, it concluded that during this time period there was a small net gain in overall wetland acres for the first time that this survey has been conducted. Others caution, however, that much of this gain was in ponds, rather than natural wetlands.
