Nice timing for a meeting.
They kept the forest natural with the natural result.
Actually, what they kept was an unnatural forest.
Fires are a natural part of a forest environment. This has always been true, but it has become more so thanks to the Indians. They used fire in many areas to clear land or suppress the growth of unwanted plants. They have been engaged in this re-engineering of the environment for thousands of years now. The plant species that grow there now have been bred to survive periodic fires. However, for the past century, we've been fighting what generations of Indians engineered into the forest. We put out fires as quickly as we can. The result is an overabundance of dead trees and dry undergrowth; "fuel" as firefighters call it. What the enviralists are trying to preserve as "natural" isn't natural at all and is only about 100 years old.
