Silvoor Biological Sanctuary is a 2.5-acre tract of land donated in 1978 to the University by Dr. Robert A. Hefner. Dr. Hefner and his wife, Ilo, spent many years converting this former town dump into a beautiful sanctuary

In 1980, Mr. and Mrs. Stuart Fitton donated a portion of their land, which was part of the Sanctuary, to Miami with the understanding that it remain a part of Silvoor Biological Sanctuary. The sanctuary houses an extensive wildflower garden with over 60 species on showy display seen during the scheduled wildflower walks or casual walks each spring.
