Minimo areale e diversità floristica in un'area a pascolo della Sardegna settentrionale

This paper takes into consideration the problem of minimal sample area, as a preliminary phase for ecological vegetation studies about Sardinian pastures. This study points out the relationship between surface and relevés representativity, from the quantitative and qualitative point of view. Minimal sample area analysis and the subsequent comparison of the phytosociological relevés highlight that, for a correct application of this evalutation method, it is necessary to choose suitable area extentions for different vegetational formations in order to reduce operator subjectivity.
