-Priority areas for biodiversity conservation in the province of Novara, Italy. A multidisciplinary approach.This research has identified the Priority Areas for Biodiversity Conservation for the Province of Novara, Piedmont Region, Italy, as a baseline for planning the Provincial Ecological Network. 26 expert naturalists participated in this operation by sharing their personal knowledge about the territory of the province of Novara for the following six themes: (a) Flora and vegetation, (b) Invertebrates, (c) Amphibians and Reptiles, (d) Birds, (e) Mammals, (f) Aquatic Ecosystems and Fishes. Experts were asked to identify the most representative focal themes for their topic and assign a naturalistic value to different portions of the provincial territory at the top for the theme. The methodology adopted, based on gathering direct information from top experts in the area, has been integrated, for some little explored portions of the territory, with GIS modeling based on land use and human pressure databases. This allowed mapping of the most important areas for biodiversity conservation. The gap analysis of Priority Areas with Protected Areas (Regional Parks, Nature Reserves, Natura 2000 sites such as Special Areas of Conservation and Special Protection Areas) allowed us to evaluate the effectiveness of these latter areas for the conservation of biodiversity. Priority Areas were actually located almost totally but not exclusively in Protected Areas. However, the Protected Areas system of the Novara province did not take into account significant portions of territory with high-value biodiversity that, thanks to this research, are now identified. Key-words:Italy, Piedmont, Novara, biodiversity, protected areas, gap analysis, conservation priority.Riassunto -Con questa ricerca sono state individuate le Aree prioritarie per la conservazione della biodiversità della provincia di Novara quale operazione di partenza al fine di disegnare, in una fase successiva, la Rete Ecologica Provinciale su basi naturalistiche. A questa operazione hanno partecipato 26 naturalisti esperti, ossia dotati di competenze personali pregresse e di adeguata conoscenza del territorio della provincia di Novara, per i seguenti 6 temi focali: (a) Flora e vegetazione, (b) Invertebrati, (c) Anfibi e Rettili, (d) Uccelli, (e) Mammiferi, (f) Ecosistemi acquatici e pesci. Agli esperti è stato chiesto di individuare i temi focali più rappresentativi per la loro disciplina e di assegnare in modo comparativo un valore naturalistico di aree diverse del territorio provinciale. La metodologia adottata, basata sull'ottenimento delle informazioni dirette da parte dei maggiori esperti presenti sul territorio, è stata integrata per porzioni del territorio poco esplorato con un'analisi in ambiente GIS sulla base di database dell'uso del suolo e delle pressioni antropiche. Questo ha permesso di cartografare le aree più importanti per la conservazione della biodiversità. La gap analysis delle Aree prioritarie con le Aree protette e con altre categorie di t...
