Measuring ecosystem novelty seems to be a difficult but necessary challenge. In this chapter the degree of novelty or compositional differences in grasslands reestablishing in ex-arable lands is described. In order to describe degree of novelty in the Inland Pampa old fields, this chapter concentrates only on biotic axes; environmental axes could follow a similar treatment. The main objective of the analysis was to describe the degree of floristic and functional group novelty in old-field successional systems of the Inland Pampa. This comparison was made at community scale, using a historical database and a regional community census. Floristic composition differed between remnant grasslands and old-field communities. While old-field grasslands did not differ in ordination position between mid-successional and later stages, the positions of remnant grasslands on the ordination axes did not overlap at all. This contribution clearly shows that novelty assessment is dependent upon whether species or functional compositions are used.
