Figur 4

Fgure 4. The development of a 25-year-old plantation of h-asp (Ekebo-mix). The plantation is located on farmland, clay loam, just outside Uppsala and is 1 ha in size. It was planted with a design of 3 x 3 m and today it stands 690 stems per ha. For details, see Figure 3. The trees are now 32-34 m in height and the plantation is particularly worth seeing (Christersson 2011).
