Most of the landscaped areas are around the Eix Nord and Eix Central roads, and these are also high-traffic areas, as they connect various faculties. There are also ornamental plants in small areas around the campus, on the roundabouts, on pathways and in the car parks.
With regard to trees, it is striking that 50% (4,795 trees) of all the trees in the landscaped areas belong to only five species: the poplar (Populus nigra), the stone pine (Pinus pinea), the cypress (Cupressus sempervirens), the hackberry (Celtis australis) and the cherry laurel (Prunus laurocerasus). There are 74 different species of trees on campus at this time.
In recent years, measures have been taken to reduce water use in landscaped areas and more species have been planted that are native or well-adapted to the area. Some striking examples of this are to be found on three roundabouts on the Eix Nord road, various gardens with aromatic plants that have low water requirements, and new trees, such as carobs (Ceratonia siliqua), sweet gums and tulip trees (Liriodendron tulipifera).
