A measurable and significant percentage of global forests is formally protected under various conservation frameworks, as supported by numerous empirical studies evaluating protected areas.
The claim is specific, empirical, and contestable, passing Step 0. The retrieved papers consistently discuss existing protected areas and global targets (such as conserving 30% of land) and measure forest cover within protected zones. There are no papers refuting the existence of protected forested lands. Therefore, the verdict is SUPPORTED.
