NREPA meaning in Governmental ?

The Northern Rocky Mountains ecosystem in the United States is known by ecologists, biologists, and naturalists as one of the last areas of the contiguous United States that is relatively undeveloped enough and large enough to support a functioning ecosystem. The Northern Rockies Ecosystem Protection Act is designed to protect this ecosystem and the many threatened and endangered species such as grizzly bears (threatened), bull trout (threatened), sockeye salmon (endangered only in Snake River Evolutionary Significant Unit, secure elsewhere), and Canadian lynx (threatened only in lower U.S. 48 states, secure elsewhere), while creating jobs that restore old roads and clear cuts. The Alliance for the Wild Rockies based in Helena, Montana has been campaigning for the legislation for two decades with the help of numerous Congresspersons, celebrities, and grassroots groups such as the Sierra Club and the Wilderness Society. The legislation has been introduced and discussed in Congress five times since 1993, most recently in November 2011 with 34 co-sponsors by December 2012.
