Approximately what percentage of old growth forest has been cut down in the United States?

The assertion that approximately 95-98% of old growth forest has been cut down in the United States is supported by historical logging practices combined with significant land-use changes since the 19th century. Old growth forests are characterized by their age, size, and biodiversity, typically featuring trees that are hundreds of years old, as well as unique ecosystems that evolved over long periods.

The vast majority of these forests have been heavily logged for timber, agriculture, and urban development, leading to tremendous losses. The few remnants that remain are often fragmented and under threat from environmental changes and human activities. The high percentage reflects the rapid rate at which these forests were cleared, particularly during the industrial era, and the ongoing challenges in conservation and restoration efforts.

Understanding the dramatic depletion of old growth forests emphasizes the importance of sustainable forest management practices, conservation efforts, and the need for policies that protect these vital ecosystems. This context is crucial for recognizing the significance of old growth forests and the challenges they face today.
