| The Sawtooth National Recreation
Area in central Idaho was created in 1972 from National Forest lands, and
remains the largest NRA in the National Forest System. It was created “to
assure the preservation and protection of the natural, scenic, historic,
pastoral, and fish and wildlife values and to provide for the enhancement
of the recreation values associated therewith” (PL 92-400). Grazing of
permitted livestock on public lands continues in accordance with the management
objective of “providing for consumptive uses of resources including . .
. grazing . . . so long as these uses do not substantially impair the recreational
and associated values for which this recreation area was established.” |

The Smiley Creek Sheep Allotment
is located at the headwaters of the Salmon River, in the southern end of
the Sawtooth NRA, within the Sawtooth Valley. The allotment includes 41,435
acres (16,768 hectares) of broad glacial trough and outwash valleys, bisected
by parallel mountain ridges. It encompasses all or part of the Vat, Cabin,
Alturas, Beaver, Smiley, and Frenchman Creek watersheds.
Vegetation is made up of
conifer trees (primarily Pinus contorta) on slopes and ridges, sage/grass/forbs
in the open valley bottoms, and willow lining the streams. Elevations within
the allotment range from 6,500 to more than 10,000 feet (1,980 to more
than 3,050 meters). Perennially flowing streams are the norm within the
allotment, although the summer of 2001 continued an unusually dry climatic
period.
In 2001, the livestock permittee
of the Smiley Creek Allotment was authorized to graze 870 ewes with lambs
between June 7 and August 28. Lambs were removed and shipped on August
28, at which time the remaining band was supplemented with another 530
ewes, for a total of 1,400 sheep. These sheep continued to graze the allotment
until trailing began on October 12.
