To provide suitable alternative grazing arrangements on National Forest System land to persons that hold a grazing permit adversely affected by the standards and guidelines contained in the Record of Decision of the Sierra Nevada Forest Plan Amendment and pertaining to the Willow Flycatcher and the Yosemite Toad.

Directs the Secretary of Agriculture to provide alternative grazing arrangements on National Forest System land to a person with a System grazing permit if such permittee's grazing privileges will be limited by implementation of the guidelines for the willow flycatcher and the Yosemite Toad (contained in the Record of Decision of the Sierra Nevada Forest Plan Amendment). States that such guidelines shall not apply in 2003 for grazing activities for which the Secretary is unable to provide alternative arrangements in specified allotments on the Humboldt-Toiyabe, Lassen, Plumas, Tahoe, Stanislaus, and Sierra National Forests.

Authorizes the Secretary to provide certain environmental exclusions for such alternative grazing arrangements without first administratively establishing an applicable category of excluded actions.
