Although no major laws were passed on the issue of conservation during Theodore Roosevelt's presidency, his support of conservation is seen as a very important aspect of his presidency. He supported conservation mainly by acting more vigorously to enforce laws that were already on the books. For example, he appointed Gifford Pinchot to be the head of the Division of Forestry in the Department of Agriculture. Pinchot worked hard to prevent excessive logging on public lands. Roosevelt also added large areas to the list of protected places. He added 50 federal wildlife refuges and approved 5 new national parks. He also used an existing law to set aside 172 million acres of forest as places that could not be logged.
