It was found that approx imately 50% of individuals have exotic origin, although the number of exotic and native species is equivalent. The number of individuals is higher in the corridors between buildings used for longer time and shorter in parking areas. It is suggested that the administrative sector of the Campus contact experts on the subject to implant a system of planning and management of green areas in order to enhance their use for conservation and environmental education without loss of landscaping
