Trees awe us with their strength, majesty, and longevity; they offer shade and respite; they give us food, something to climb, places to hide; they literally give us clean air to breathe. A new addition to the lively Audubon lineup, this calendar celebrates the diversity and splendor of the world's trees. Each month's beautifully photographed image is a testament to the power of nature and a reminder of the important of preservation.
