Based on the spatial scale, authors distinguish several levels of biodiversity: α diversity (for an ecosystem), ß diversity (for ecosystems within a complex), γ diversity (for a regional complex of ecosystems), and δ diversity (for a macro-regional complex of ecosystems). Taking into account this “diversity of diversities”, the paper recommends a hierarchy of methods that could be used to assess the impact of urban and spatial plans on biodiversity. Based upon the classification of the Nomenclature of Territorial Units for Statistics (NUTS), anthropogenic impact could be measured for urban plans (NUTS V) and county plans (NUTS III) by looking at changes in land use, e.g., using CORINE data. At regional (NUTS II) and national (NUTS I) levels, diversity can be assessed within the biogeographical regions, and the impact on it by the decrease of the areas covered by less represented or vulnerable classes, such as the Black Sea and alpine regions.
