Priority Zones<br />

Les zones prioritaires<br />
pour les paysages agro-sylvo-pastoraux méditerranéens<br />
Abstract<br />
The conservation of <strong>Mediterranea</strong>n protected<br />
agro sylvo pastoral landscapes very often has to<br />
reconcile conflicting forces related to socio-economic<br />
interests on the one hand and the needs<br />
of biodiversity protection on the other. These<br />
latter can be relevant in defining the environmental<br />
ranges and the biological constraints on<br />
which a sustainable use of protected landscapes<br />
should be developed. In this regard, the design<br />
of protected areas and their zoning play a pivotal<br />
role determining where and which activities<br />
should or should not be carried out. This<br />
paper considers two neighbouring parks in<br />
southern Italy, both characterized by large<br />
expanses of <strong>Mediterranea</strong>n steppe grasslands<br />
and inhabited by the largest Italian population<br />
of the lesser kestrel (Falco naumanni). In the<br />
study area, the lesser kestrels nest mainly in the<br />
historical centres of the towns surrounding the<br />
parks and feed in large open areas occupied<br />
mainly by cereal crops and steppe grasslands.<br />
Given the ecological role and the high conservation<br />
value of the lesser kestrel, the design of<br />
the two parks should encompass those areas<br />
needed to preserve the local population. In<br />
order to determine whether steppe variables<br />
(amount and types, at different distances from<br />
nest sites) were significant predictors of the<br />
colony sizes (dependent variables) of the lesser<br />
kestrel, a multiple linear regression analysis was<br />
conducted. The analysis showed colony size to<br />
be correlated significantly with the amount of<br />
steppe within a radius of 7.5 km of the nesting<br />
site. On the basis of these results, we identified<br />

and delimited in each park the so-called “Priority<br />
Zones”, that is the zones that should be the<br />
major focus of conservation efforts. We then<br />
compared the boundaries of these “Priority<br />
Zones” with those of the parks, as they were<br />
already defined, highlighting the implications<br />
for biodiversity conservation.<br />
Résumé<br />
La conservation des paysages agro-sylvopastoraux<br />
protégés en Méditerranée doit très<br />
souvent concilier, d’une part, les conflits relatifs<br />
aux intérêts socio-économiques et, d’autre part,<br />
les besoins de protection de la biodiversité. Ces<br />
derniers peuvent constituer des éléments pertinents<br />
dans la définition des mesures environnementales<br />
et des contraintes biologiques à partir<br />
desquelles un usage approprié des territoires<br />
protégés peut être développé.<br />
Dans ce cadre, les projets d’espaces naturels protégés<br />
et la détermination de leurs superficies<br />
jouent un rôle fondamental en déterminant où<br />
et quelles activités devraient ou ne devraient<br />
pas être effectuées. Ce travail considère deux<br />
parcs proches, dans l’Italie méridionale, tous les<br />
deux caractérisés par de grandes surfaces de<br />
steppes méditerranéennes et habitées par les<br />
