From the sharp spires of spruce and fir atop Otter Cliffs to the gnarled birches of Cadillac Mountain and the jack pines of Schoodic Point, the trees of Acadia define the park’s landscape. Among the oldest and healthiest forests in the eastern United States, these woodlands support diverse wildlife, protect lakes and streams, and store carbon while bridging northern boreal and southern temperate ecosystems. Through history, scientific research, and stunning photography, this book invites readers to explore Acadia’s forests across all four seasons and discover the beauty and importance of preserving these remarkable trees for the future.
