Which law restricts the harvest of native plants and allows only licensed nurseries to sell them?

The correct answer relates to the Preservation of Native Flora, a crucial law aimed at protecting Florida's native plant species from overharvesting and illegal trade. This legislation recognizes the ecological importance of native plants and establishes regulations to ensure their sustainability. By restricting the harvest of these plants to licensed nurseries, the law helps to preserve biodiversity, maintain the integrity of natural ecosystems, and promote responsible horticultural practices.

Licensed nurseries are typically required to adhere to specific guidelines that ensure ethical sourcing and cultivation of native plants. This structured approach not only safeguards native species but also supports the local economy by promoting responsible horticulture. The other options do not specifically pertain to the regulation of native plant harvesting and distribution, making the Preservation of Native Flora the most relevant choice in this context.
