• very high assets: average > 1.5 standard<br />

deviations: score = 15<br />

The input data are classified according to their<br />

inherent differences, without a subjective rating<br />

of 'good' or 'bad'. For example, areas in northern<br />

Scandinavia with a low proportion of farmland also<br />

score low with regard to HNV farmland, but this<br />

does not mean that these areas have few natural<br />

assets.<br />

Maps 10.2 and 10.3 present the natural and<br />

environmental assets for the EU‐27, and mountain<br />

massifs within these countries, respectively. Even<br />

in Map 10.2 it can be seen that mountain massifs<br />

generally stand out; but it should also be noted<br />

that there are significant areas with high levels of<br />

natural and environmental assets in other parts of<br />

the EU‐27, including much of Sweden, Finland and<br />

Estonia.<br />

Table 10.5 permits a comparison of the relative<br />

proportions of natural and environmental assets<br />

across the massifs, though considering only the parts<br />

within EU Member States. As can be seen in column 2<br />

(data for class 0), large areas in the Nordic mountains<br />

(Norway) and the Balkans/South-east Europe are<br />

not considered and are not discussed further below;<br />

no results are shown for Turkey. The massifs that<br />

have very high assets (class 5) over particularly high<br />

proportions of their area are those of the British<br />

Isles (59 %), western Mediterranean islands (25 %)<br />

and Iberian mountains (22 %). Many more massifs<br />

have high assets (class 4) over particularly high<br />

proportions of their area: Pyrenees (44 %), Iberian<br />

mountains (31 %), Alps (29 %), French/Swiss middle<br />
