4 Additional environmental information 4.1.2 Background As basis for this section there is a separate report in Swedish called ”Applikation av Biotopmetoden 2005, Bilaga till Vattenfall AB Nordens certifierade miljövarudeklaration EPD för el från Vattenfalls vattenkraft i Norden” which can be ordered from Vattenfall. The 14 selected hydropower stations occupy an area of in total 74 850 hectares, predominantly river-, lake, and annual reservoirs, which amount to 70 320 hectares. This reservoir area constitutes 38 % of Vattenfall’s total reservoir area and the 14 stations generate 31 % of Vattenfall’s hydro electricity. This means that selected hydropower stations have more reservoir area than Vattenfall average.

It is important to note that studies of individual power stations do not provide a comprehensive picture of ecological effects in a river. It would be misleading to relate biotope changes to the electricity generated at a single power station. This would be to the disadvantage of stations with annual reservoirs, and to the advantage of stations with no or short-term reservoirs. Therefore, ecological effects for entire catchments should be quantified from a representative selection of power stations. Norra Norrland is represented by stations in the river Lule älv. Mellannorrland is represented by stations in the rivers Ume älv, Ångermanälven, and Indalsälven. Södra Norrland and Västsverige are represented by stations in the rivers Dalälven and Göta älv respectively. 4.1.3 Results The land use and quality levels used at the various stations are specified in the table below.

Several stations have posed a problem because pre-exploitation data is missing due to lack of aerial photographs and inventories, particularly for stations built in the 1950´ies and earlier. The large proportion of quality level C2 reflects this. Note that biotope impact is overestimated when characterisation keys are applied in quality level C.
