The river corridor, within the Central Flyway of North America, provides habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane (Grus americana) , the piping plover (Charadrius melodus)

. The broad shallow waters of the Platte near its confluence with the Missouri River constitute an important habitat for at least one endangered species of fish: the pallid sturgeon (Scaphirhynchus albus)

The agreement seeks to develop a recovery implementation program to improve and conserve habitat for the four listed species and seeks to enable existing and new water uses in the basin to proceed without additional regulatory actions related to the species. In 2003, DOI, with input from the Governance Committee of the state-federal partnership, asked the National Research Council to evaluate the scientific validity of the instream flow recommendations, habitat requirements for the species, and connections among the physical systems of the river related to the habitat as specified by the U.S.

Ecological changes in the central Platte River also have had habitat implications for other species, such as neotropical migrant birds that have been favored by expansion of riparian woodlands. Whooping cranes, federally listed in 1967 under the Endangered Species Preservation Act, are the rarest species of crane in the world (Figure 1-3)

. By the 1980s, the range for the interior least tern in the central Platte River had shrunk to include only a portion of the Platte River Valley between Kearney and Grand Island, and the bird was a rare migrant and an infrequent nester.

An example of the complications is the relicensing of hydroelectric projects by the Federal Energy Regulatory Commission.

The settlement of the negotiations included permission for the projects to continue and support for a recovery effort that encompassed areas downstream along the Platte River. During the 1990s, recovery efforts included work by the Whooping Crane Trust and the National Audubon Society to modify habitat in the river corridor.

In early 2003, the Research Council formed the BOX 1-1 Statement of Task A multidisciplinary committee will be established to evaluate habitat needs of four federally listed species: the whooping crane, Northern Great Plains breeding pop ulation of the piping plover, interior least tern of the central Platte River, and pallid sturgeon of the lower Platte River (below the mouth of the Elkhorn river)

RECOVERY: Not defined in the Endangered Species Act. Defined in regulations issued by USFWS to mean improvement in the status of listed species to the point at which they would no longer qualify as endangered or threatened.

an advanced computer model, SEDVEG, to evaluate the interactions among hydrology, river hydraulics, sediment transport, and vegetation for the Platte River -- the model is being developed by USFWS but has not yet been completed or tested; (3) an evaluation of the models and data used by USFWS to set flow recommendations for whooping cranes that is being developed, but has not yet been completed, by USGS; and

Chapter 8 summarizes the committee's conclusions and recommendations and presents succinct answers to the specific questions outlined by the Governance Committee. In the 1870s, John Wesley Powell correctly predicted the high degree of variability of water resource supplies along and west of the 100th meridian, but he could not foresee the changes that have occurred in general climate, land use, and land cover and in the fundamental physical and biological characteristics of the Platte River in the vicinity of the meridian.
