Abstract

the vegetation of the Po Plain has long been modified by natural and human factors. the present plant landscape is almost entirely anthropogenic. Many hydro-hygrophilous species, quite common until a few decades ago, are now very rare and in danger of extinction, so conservation programmes are necessary for their protection and maintenance. it is known that the former vegetation can be reconstructed thanks to palynological data, but assessing the real presence of a given species is not always possible. this work aims to understand whether palynology can give information about the presence and identification of hydro-hygrophilous species, supporting the classical flora analyses commonly conducted on herbarium data. in some cases, these species are well characterized from a morphopalynological and phytogeographical viewpoint: the plant occurrence may be suggested even by pollen findings in surface-samples. discovering the presence of some of these species by pollen morphotypes offers a real opportunity to gear the reintroduction/reinforcing programmes, but ecological analysis will obviously be essential to ascertain the real suitability of the chosen sites, according to the ecological requirements of the species. our analysis refers to wetlands of the southern Po plain within the Modena Province, where detailed palynological data about present and historical local flora were available.
