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.
