Abstract

In the  experimental forest Aelmoeseneie at Gontrode (Belgium), a 12 year old  artificial plantation of grey alder has been analysed on growth, structure  and shape characteristics.     In the plot some ten tree cells and tree pairs were examined in particular.  The tree cells consisted of one central tree, which was surrounded by six  other ones. The tree pairs were the dominant tree and the most dominated tree  in these cells.    In the first place height, diameter, basal area and leaf mass were determined.  Then, the vertical and horizontal structures were analysed, with special  attention being paid as well to the social differentiation in the tree cells  as to the crown areas. Finally, several tree shape characteristics were  determined.     The alder grew very well. The internal competition and differentiation had  already started. The position of the dominant trees, however, is not  stabilised yet.     The treatment of the thicket, in continuity with the thinning, will be  necessary in the next future.
