Answer: The answer is an old growth forest
Explanation: Old growth forests are also known as Virgin forests because these forests have been in existence for a long period of time (usually hundreds of years) without any disturbance. The disturbance could be in the form of human activity like logging or natural activities like wildfire and windstorm.
These forests usually have distinct ecological features like large trees and multilayered canopies. They are habitat for many rare plant and animal species like the northern spotted owl, marbled murrelet and fisher.
