Who responsibly for turning 150 million acres of government-owned timberland into forest reserve?

The responsibility for turning 150 million acres of government-owned timberland into forest reserves primarily lies with the U.S. government, particularly through actions taken during the early 20th century under the leadership of President Theodore Roosevelt. Roosevelt established the U.S. Forest Service and signed the Antiquities Act, which facilitated the creation of national forests and reserves to protect these lands from deforestation and degradation. His administration's conservation efforts marked a significant shift toward preserving Natural Resources for future generations.
