There are few experiences related to the study of the natural forests and grasslands belonging to the so-called Espinal in Santa Fe, Argentina. The present study was carried out in Sa Pereira (31° 34' S, 61° 22' W, Argentina), in an approximately 100 ha relict of Prosopis. Its objective was to make a quantitative and qualitative description of the current vegetation. A systematic stratified sampling was carried out on sixteen 10 m per 100 m plots. The variables recorded were: tree species, diameter at breast height, tree height and stem height. The health status, stem straightness, sociological position and crown vitality of every individual were also determined. The results showed predominance of Prosopis alba (46 %), Acacia caven (19 %), Celtis tala (18 %) and Geoffroea decorticans (15 %). Exotic species such as Morus nigra, Melia azedarach and Ligustrum lucidum were also observed. The average basal area of ​​the forest was 12 m2/ha; its sanitary state was regular but its structure irregular. Significant differences as to average diameter at breast height, average tree height and stem height were observed in the plots. The predominant shrubs were Acacia praecox and Grabowskia duplicata; occurring from semi-enclosed shrubland sections to parts without shrubs.
