Provides for annual land use fee adjustments.

Reduces the land-use fee, but not below a minimum amount to be determined by the Secretary, for: (1) use by persons with disabilities and at-risk children; and (2) youth programs through organized social, citizenship, character-building, or faith-based activities oriented to outdoor recreation.
