In summer 2001, UT's Department of Ornamental Horticulture & Landscape Design (OHLD) and the plant personnel of the Department of Plant & Soil Sciences (PSS) joined to form a new department, named the Department of Plant Sciences & Landscape Systems (PSLS) on an interim basis. The PSS soils personnel joined the Department of Agricultural & Biosystems Engineering (ABE), which changed its name to Department of Biosystems Engineering and Environmental Science (BEES). Merger announcement, May 15, 2001. As of July 1, 2003, the new and official name of the department became Department of Plant Sciences. Our curricula, research and extension programs remain intact. Please contact us if you any questions about the reorganization or questions about any of our programs. Thanks for visiting!
