What is the main idea of wildfires are not all bad?

Many are also used to prevent forest fires. Even before human involvement, natural, low-intensity wildfires occurred every few years to burn up fuel, plant debris, and dead trees, making way for young, healthy trees and vegetation to thrive. That new growth in turn supports forest wildlife. Forest managers are now replicating this natural strategy when appropriate, starting manageable, slow-burning fires to make room for new life that will help keep the forest healthy in the long term. All fire is risky. To minimize that risk as much as possible, controlled burns must be well-considered, well-planned, and ignited and maintained by trained professionals. The bottom line? Fire can be a tool for conservation, but only when used the right way.
