The management referencing concept is part of the silvicultural
management strategy applied in the municipal
forests of Lübeck and Göttingen (Fähser 1995;
1998) while the management demonstration concept is
being used in German State Forests (Böckmann &
Hüsing 1999). Nöllenheidt (2000) presented a study in
which different plot designs were compared. Based on
the comparison, he proposed a design where the management
demonstration plot represents the core area
within a management demonstration forest (Fig. 2). All
the diameters, heights and position coordinates of all
trees within the plots were measured.
