Tongass National Forest –Seventeen million acres in SE Alaska. Americas largest National Forest. This region is projected to become warmer over the next century. The trees will grow more vigorously but fungi that cause rot will also thrive, there is likely to be an increase in wind throw, and fire risk. Despite decades of clear-cutting its best old-growth habitat, the majority of the forest is considered one of the most intact expanses of temperate rainforest remaining in the world and is home to endangered and rare flora and fauna. It provides habitat for all five species of Pacific Salmon, humpback and orca whales and some of the largest concentration of brown bears and bald eagles in the US. The forest safeguards wildlife found nowhere else on the planet. The giant old-growth trees some of which are 800+ years old are also a warehouse of carbon, helping regulate the planet’s climate.
