The Clean Water Act (CWA) includes as one of its goals restoration and maintenance of the chemical, physical, and biological integrity of the Nation's waters. The CWA established various programs to accomplish that goal. Among the programs is a requirement for states to establish water quality standards that will allow protection of the designated uses assigned to each water body. Once those standards are set, state agencies must sample the water bodies to determine if water quality requirements are being met. For those water bodies that are not achieving the desired water quality, the state agencies are expected to develop total maximum daily loads (TMDLs) that outline the maximum amount of each pollutant that can be discharged to the water body and still maintain acceptable water quality. The total load is then allocated to the existing point and nonpoint sources, with some allocation held in reserve as a margin of safety. Many states have already developed and implemented TMDLs for individual water bodies or regional areas. New and revised TMDLs are anticipated, however, as federal and state regulators continue their examination of water quality across the United States and the need for new or revised standards. This report was funded …

The subantarctic forests of South America are the world’s southernmost forested ecosystems. The birds have sung in these austral forests for millions of years; the Yahgan and Mapuche peoples have handed down their bird stories from generation to generation for hundreds of years. In Multi-ethnic Bird Guide of the Subantarctic Forests of South America, Ricardo Rozzi and his collaborators present a unique combination of bird guide and cultural ethnography. The bird songs, names and stories recorded on the CDs of the guide book includes entries on fifty bird species of southern Chile and Argentina, among them the Magellanic Woodpecker, Rufous-Legged Owl, Ringed Kingfisher, Buff-Necked Ibis, Giant Hummingbird, and Andean Condor. Each bird is named in Yahgan, Mapudungun, Spanish, English, and scientific nomenclature. As a whole, the recordings of this guide book express the voices of multiple species and indigenous, rural and urban cultures, whose lives are interwoven in the temperate forest region of South America.
