The present paper provides new floristic data concerning the locality “Colle Pardo” (Municipality of Ariccia, of Rome, Latium, Central Italy) which is included in the Castelli Romani Regional Park. The floristic surveys were carried out from 2012 to 2014, and allowed to record 377 taxa, of which 77 are to be considerd as new for Regional Park, 2 taxa are new records for the Flora of Lazio. Biological and chorological spectra and a discussioned about the importance in terms of public conservation area were also given.

The checklist is based on the floristic reports and literature from 1947 to today, and on diversity-richness surveys conducted from 2011 to 2013 in the framework of the Europe-an project LIFE09 NAT/IT/000118 Ri.Co.Pr.I. "Restoration and conservation of arid grasslands of central-southern Italy". The research led to identification of 864 species and subspecies of vascular plants in an area of 270 km2, of which 828 native and 36 alien. Italian endemic taxa are 54 and 105 taxa are protected at various levels. These data provide a preliminary framework for future research and confirm the plant diversity of the Natura 2000 sites and the areas recognised for protec-tion as “Important Plant Areas (IPAs)” by the Italian Ministry of the Environment and Pro-tection of the Territory and the Sea.

Although precise measurement of the degree of danger represented by active ingredients is difficult, it is possible to identify a degree of toxicity (P) on the basis of the symptoms provoked. Applying this classification to the spontaneous plants of Rome, we find 12 taxa capable of causing coma and/or death, 98 with marked toxicity, 67 with moderate toxicity and 53 with low toxicity (total of 230 taxa). Taking the 230 taxa, we then calculate a Risk Index (R = P %), where R is the probability of an event capable of harming people. Calculating the index for all the taxa, we find that only two of the 12 highest-toxicity (P=4) plants show a high degree of risk. However a number of less toxic (P=3), but more widespread plants, also show high risk. The same classification and risk calculation can be conducted for ornamental plants, cultivated in gardens or apartments.
