Handbooks for monitoring species and habitats of Community interest (Council Directive
92/43/EEC) in Italy: animal species
The Habitats Directive requires Member States to implement surveillance of the conservation status
of habitats and species of Community Interest. The aim of this handbook is to outline the methodological
instruments for implementing a monitoring program of the Italian animal species, as required by art. 17,
with particular reference to data collection at site level.
The European guidelines require the assessments to be carried out by compiling information on
specific parameters at biogeographical scale. For each animal species, four parameters have to be
considered and combined to obtain an overall assessment of conservation status for each
biogeographical region at national level: "Range" (based on actual distribution), "Population", “Habitat
for the species” and "Future Prospects". Monitoring programs need to collect data dealing with the first
three parameters at a local level.
In this handbook, a monitoring form is presented for each animal taxon (species, subspecies or
species group) of Community interest occurring in Italian terrestrial and inland water environments.
Altogether, the volume contains 151 forms, referring to 215 terrestrial and inland water animal taxa.
Further species, which will be reported in the IV National Report under a common name due to
difficulties in recognizing them in the field or their doubtful status, are mentioned and discussed as well.
Monitoring methods have been defined with the support of five national Scientific Societies, and
reviewed by personnel of the Italian Regions and Autonomous Provinces. The monitoring forms thus
report the most effective available techniques and provide an operational guidance for data collection
and monitoring scheduling with the aim of standardizing data collection efforts across Italy. A
standardized basis of information is indeed important for assembling data at national level and producing
comparable assessments on the conservation status and future prospects of each animal taxon

No full textFor their rapid and alarming decline, the Italian populations of the Italian spadefoot toad (Pelobates fus-cus insubricus) are of high conservation importance. In this study we examined habitat use by the spadefoot toads
in north-west Italy, where one of the largest remaining populations lives. We used compositional analysis and logis-tic regression models to elaborate land-use and soil composition in order to determine the habitat preferences of the spadefoot toads. We found that the two main variables predicting the occurrence of spadefoot toads in the study area were the percentages of sandy-loam soil texture and the presence of Entisols. Our results showed that spadefoot toads preferred soils that keep soft and malleable structure: Entisols with sand texture, where sand represents the major component, and mature soils, with a high degree of pedogenesis and a relatively high natural fertility and humidity. Conversely, Pelobates fuscusavoids Inceptisols, probably too hard to be dug by the species. This study demonstrates that, at least in the Italian range, the choice of areas in which to reintroduce P. fuscus, or where re-create favourable habitats for it, must take into account the soil types, which, in intensely cultivated areas, seems to be decisive for the possibility of survival of the species in the medium and long time
