WUPAs were delimited based on the definition "rural areas situated at least 30 km.
Data were processed using ArcView 3.X and its extensions: (1) clipping all data by WUPAs using the Spatial Analyst for comparisons with the national results; (2) computing total area, overall or by categories (biogeographical or ecological regions, land cover and use and its changes, natural protected sites); (3) for climate and elevation data, the X-Tools extension was used to dissolve all limits between the squares or parts of them within each administrative unit, while computing average values; and (4) each land cover and use change was attributed to certain transitional dynamic, using the classification by Petrisor (2012), but adding several items.
WUPAs seem to have a random distribution, but relatively uniform over the national territory; they cover the central area to a lesser extent.
Again, the position of WUPAs in mountain areas or wetlands explains their predominant coverage with forests (and semi-natural areas), wetlands and water bodies, with shares exceeding the national averages.
Again, some of the most important national results, presented by Petrisor (2012), do not seem to be equally important for the WUPAs. For instance, the two antagonist phenomena affecting agriculture (abandonment and development) and urbanization have lower shares, explained by the lower shares of agricultural and urban areas.
The climate of WUPAs differs from the Romanian one, benefitting upon lower temperatures, but has lower precipitations.
Within the WUPAs, the overlapping percentage is larger: 180.87%.
