Abstract
The Po Plain (Northern Italy) is one of the most urbanized areas in Europe. In such a territory, where ecosystem degradationreached critical levels and the agricultural matrix is prevailingly intensive, small fragments of hilly oak-hornbeam forestsstill persist. Examples of well preserved forests of the Po Plain are those of the Monte Netto Regional Park that representsirreplaceable refuges for both sedentary and migratory species. In this paper we present a preliminary list of Coleopterainhabiting the Park collected during 10 years of field surveys using several sampling techniques (hand netting, beatingtray, sight-collecting and collecting under bark; water nets; litter reducers, light traps; aerial sweet-bait trap; cross-vanepanel trap, pitfall traps, Malaise traps, window traps, and walking transects). Specific samplings were also made in treehollows and by car-netting. To date we have identified 834 species belonging to 531 genera and 71 families (severalspecimens and some families are still undetermined). Among all the species identified, 31 were non-native while 202were included in the Red List of Italian saproxylic beetles, 12 of which were in threatened category. The high beetlerichness and the presence of many endangered species recorded during this survey, emphasises the conservation valueof Monte Netto. Moreover, the discovery of species linked to old and stable forest systems, such as Osmoderma eremita,Oxylaemus cylindricus, Pycnomerus terebrans or Xylotrechus antilope suggests how, despite their small size and the factthat they are surrounded by agricultural land, the remaining forest patches of Monte Netto still possess a fair level ofnaturalness, especially in the internal areas of the larger plots. Future targeted research, also intended to cover other partsof Monte Netto, could increase our present knowledge; however, and at least in the number of families, we do not expecta substantial increase in species richness.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
