U.S. Old-Growth Forest Protection Uncertain Without Clear Definitions

The state of old-growth and mature forests in the U.S. remains uncertain due to disagreements on definitions, with no national inventory or framework currently in place. These forests, crucial for ecosystems and carbon storage, make up only 6% and 32% of total U.S. forests respectively. Recent efforts, such as the reinstatement of roadless protections in the Tongass National Forest, aim to safeguard these vital habitats.

Scientists from The Wilderness Society have stepped in to address the issue. Mary Byrd Davis and David N. Wear developed a categorization system based on biomass to define old-growth forests, marking a significant stride towards standardization. Their work has led to the creation of a national inventory of old forests in the United States.

The Joe Biden administration has taken initial steps to protect these forests, but experts agree that more work is needed. Protecting old-growth and mature forests is vital for mitigating climate change, supporting local communities, and preserving wildlife. Logging-free forests are particularly crucial for threatened species.

With only a small fraction of U.S. forests classified as old-growth, determining their current state and standardizing definitions are crucial next steps. The reinstatement of roadless protections in the Tongass National Forest serves as a positive example of how these forests can be safeguarded. The Biden administration's efforts, along with ongoing scientific research, are paving the way for consistent conservation policies that benefit both the environment and communities.
