However, to be pragmatic and realistic, the 15% target is in fact unattainable within 2020, so any initiative that would increase the restoration activity is a contribution. One challenge is that a specific nature type may be defined in different ways, so the same type of nature ends up in different categories in the different countries. Data on wetlands in Table 4.3 is a good example, as it is perhaps not likely that wetland in good conditions in Norway (1.1% in level 1) is so much worse than in Finland (73% in level 1). This illustrates that the present datasets and definitions are unsuitable for a comparison between countries directly, but can be useful for helping countries realize the need for improved statistics and elaborating existing data.
