Both City and East campuses include academic and research facilities, libraries, recreation centers, and residential buildings. They both feature various support buildings for power and networking, as well as in-ground infrastructure supporting advanced computing, power distribution, and energy-efficient heating and cooling from central plants. Both campuses are heavily landscaped, with the grounds functioning as a research mission of the university; they are administered as the UNL Botanical Garden and Arboretum, which handles major plantings including Cather Garden on City Campus and Maxwell Arboretum on East Campus.
