Any method for identifying priority conservation areas should take into account the effect of the surface area on species richness. We examined the importance of the plant species-area relationship in a set of 79 areas with a Mediterranean-type climate of the southwestern Mediterranean Basin. The results confirm that the plant species-area curve for Mediterranean grasslands and woodlands in this region fits a power function model. Examination of species per area ratios for these areas suggests also that it is better to have several reserves of medium size (less than 100,000 ha) than only one large reserve to support the highest number of plant species at the least cost of protection
