Portions of the property are open to the public during posted hours only. Established on abandoned agricultural land, the 716-acre Kellogg Experimental Forest is known worldwide for research on tree breeding and genetics, planting techniques, and plantation establishment and management. Much of the research that developed the Spartan spruce, a hybrid that combines the color and drought resistance of a blue spruce and the softer needles and rapid growth rate of the white spruce, was done at the Kellogg Forest. Over 157 tree species from around North America and the world can be found at Kellogg Forest. Currently, research is being conducted that focuses on regeneration of native hardwood species and the many variables that hinder this process. The forest is open to the public to recreate during posted hours only. Some areas of the forest have limited or restricted public access. This is related to visitor safety, security, and protecting the integrity of research. Please respect signage and the privilege to recreate on such a unique landscape.
