Field experiments with trees require quite large and homogeneous areas. For the present study large amounts of freshwater of relatively constant quality were needed to produce artificial rain. Since groundwater is much more constant in composition than surface water, areas with easy access to groundwater are also desirable. Two areas (A and B) in south Norway were found suitable for the experiments (Fig. 2.1). Area A is located in Akershus county (11°06′ E.Gr. 60°16′ N) about 45 km north of Oslo at an elevation of 200m. Area B is located close to the small town Åmli in the county of Aust-Agder (8°30′ E.Gr. 58°48′ N) at an elevation of 155m. Three experiments (A-1, A-2, and A-3) were established in area A, and two experiments (B-1 and B-2) in area B.
