Hemlock-Northern Hardwood Forest
This group opened in 1973, and is also known as the Pennsylvania Hardwood Forest Group, and today is labeled as the Tionesta Scenic and Research Area. The plants were created by Elizabeth Niedringhaus and her team of volunteers, and the background was painted by Daniel Riccobon. It was sponsored by the Pittsburgh Garden Center and over one hundred of its affiliated garden clubs, and an anonymous donor sponsored the background. By this time, Dorothy Pearth had taken over as Associate Curator, although Henry participated in the planning for this diorama as Curator Emeritus. The group is based on an expedition to the Tionesta Tract that took place in 1972, and was again part of Jennings’ original vision, as a special example of a climax forest.
