Fla. Stat. § 378.031

It is the intent of the Legislature to provide an economic incentive to encourage the reclamation of the maximum number of acres of eligible nonmandatory lands in the most timely and efficient manner or the donation or purchase of nonmandatory lands, especially those lands for which reclamation activities will result in significant improvements to surface water bodies of regional importance in those areas of the state where phosphate mining has been permitted. The Legislature recognizes that certain lands mined or disturbed prior to July 1, 1975, have been naturally reclaimed.
