d. that are subject to severe wild fires to remove fuel load and stimulate new growth

Answer 1

The correct answer is D: that are subject to severe wild fires to remove fuel load and stimulate new growth. Certain forest regions have adapted to periodic wildfires, as the fires remove accumulated dead tree mass and stimulate the germination of seeds of certain plants. Some forest areas do not experience sufficient fires due to management by people, often to protect human assets such as forest plantations or buildings. Managed fires can be used as a substitute for wild fires to facilitate the natural processes that depend on wild fires.
