In 1987, a lawsuit was filed against the Solo Timber Sale by the Sierra Club to stop logging the groves. The judgement made for that lawsuit was that the groves would be restored to their natural state. The 1990 Mediated Settlement Agreement (MSA) to the Sustainable land management plan extended the grove boundaries and prohibited timber harvesting within the groves. In 1992, President Bush visited the large sequoias and boosted the terms by completely protecting them from harvesting, mining, and development.
