Norwegian stoneflies II 215 of Finnmark, northern Norway and can in this sense be compared with the inner areas of Rogaland (area 1). The main differences are in latitude, vegetation belts and in the fact that the oceanity factor is much lower. Area description Ten streams and 2 lakes were investigated in the area. The central parts consist largely of sandstone and greenstone, while the peripheral parts consist of little altered Eocambrian sediments. Drift material is present, especially in the stream valleys. The climate has a pronounced continental character. Precipitation generally lies between 400 and 600 mm a year, although the southern parts can have below 400 mm. The June isotherm is similar to the inner fjords of area 1 (western Norway). The July temperature is lower and can be compared to the western coastal areas or the mountain areas of southern Norway. In the Alta area there are deep valleys which converge on the fjord at Alta. In the southern and eastern parts of the area, mountains between 800 and 700 m a.s.l. are common, while in the western parts the landscape is generally higher, with mountains of 1100 m a.s.l. and above. Around the village of Alta and the lower parts of the valleys there are pine woods, mixed with willow, alder and other deciduous trees. Above this, in the Sub-Alpine belt, there is largely birch and willow. Stream descriptions The main river in this area is the River Alta. In addition, there are numerous small and large streams. In places there is a dense fringe of deciduous trees along the streams which consists mainly of willow, alder and birch. In the Sub-Alpine belt willow dominates alongside the streams and may be very dense and high in the lower sections. Higher up the bushes are lower, but growth may still be dense. In the Alpine belts the willow gradually disappears (Figs. 9, 10). Calcium hardness was measured both during 1968 and 1972 in several places, and values varied between 0.9 and 2.7 mg Ca++/l. Values of pH lay generally between Fig. 9. Stream by Leirbotnvann in the Sub-Alpine belt. Fig. 10. Stream in Stokkedalen in the Low-Alpine belt. 6.0 and 6.8, although somewhat lower in the higher areas. Stonefly fauna In this area 18 species of stoneflies were taken (Table VIII). Of the five species which are restricted to northern Norway, only two were represented, N emoura arctica and Nemoura sahlbergi. The dominant carnivore was Arcynopteryx compacta, which occurred in lakes, lake outlets, and in streams. Diura bicaudata was also common and was taken in streams, lakes and lake outlets. Diura nanseni was taken in streams and lake outlets and all three species were taken together in the outlet of a lake (Fig. 10). The most common herbivores were Capnia atra, Leuctra hippopus, and Nemoura cinerea. In this area 16 species were taken in streams, 7 in lake outlets, and 5 in lakes.
