This poster is a dynamic portrayal of the biodiversity of Spring Creek Watershed in central Pennsylvania using colorful and technically accurate drawings of more than 20 species of animals and plants found in the watershed. The full color poster, 40 inches high by 26 inches wide, was drawn by artist Nils Obel of Camden, Maine, and conceived and produced by Robert P. Brooks, Director of the Penn State Cooperative Wetlands Center, for the citizens’ group, the Spring Creek Community. Copies of this poster are available for $10 each ($5 each for 10 or more), including shipping.
