| Size of Areas of Defined Use (E2) |

|
Each type of land use creates its own habitats with adapted animal and plant communities. If the use of the landscape changes, so does the composition of these life communities.
For the purposes of E2, the Swiss countryside is classified into 13 types that reflect land use and surface characteristics. If a particular type of use increases or decreases, this has consequences—either positive or negative—for the flora and fauna concerned. Thus, such changes can only be interpreted in conjunction with other BDM indicators (in particular Z7/Z8/Z9).

Interpretation example
According to area statistics for the period 1979 to 1985, the built-up zones of Switzerland covered 118,105 hectares. This figure had risen by 16.5% by the time of the second survey (1992 to 1997). The entire built-up area grew by 13.3% over the same period.
Comments
• The appendix shows how the area-statistics categories are assigned to each of 13 types of land use.
• The data record does not allow for any distinction between farmland and land left to pasture in the long term. In the case of long-term pasture land, Alpine farming areas are not included; these are assigned to the category denominated “shrub and foliage vegetation, cleared woodland”. Farmland in Switzerland covered an area of 404,604 hectares in 1985. This area had grown by 3.9% by 1996. By 2002, the amount of land being farmed was less than it had been in 1996.
• Almost two thirds of land surface consists of woodland and areas largely left to nature.
• Built-up areas have grown by about 13%.
• The area dedicated to fruit farms, vineyards and market gardens of long standing has shrunk by over 14%, due above all to the loss of mature fruit trees.
• While marginal areas of scrub and brush land are shrinking, those of thick woodland are growing.

| Significance for biodiversity |
| |
| Each of the 13 areas of defined use harbors specific communities of typical animal and plant species. Putting an area to different use changes the number and the combination of species living there. Providing information about the uses areas are put to, the E2 indicator also reports on habitat changes. However, it is not possible to directly deduce an increase or decrease in biodiversity from changes in areas of defined use. Such conclusions can only be drawn taking other BDM indicators into account as well. |
