Deep in the ancient forests of the Pacific Northwest live some of the oldest and largest trees in the world. For centuries, Douglas firs and cedars have towered above the forest floor. But these majestic trees are only part of the rich areas known as old-growth forests. They are home to hundreds of plant and animal species.

Old-growth forests used to extend across the Pacific Northwest, but these precious habitats are quickly disappearing. In some cases, logging has destroyed the forest animals’ habitats.
