The images for the 2009 Trees of Boston Calendar were all taken in the Arnold Arboretum, part of Boston's Emerald Necklace. Home to thousands of species of flora from around the world, the park is Erik's photo destination of choice.
The photographer thanks the Arnold Arboretum of Harvard University for the use of its collection. Five percent of net proceeds will be donated to the Friends of the Arboretum.
