A scaffolding has been installed on the field site, allowing access to the sun crown (3.50 m) and the shade crown (0.80 m) within the experimental plot. The scaffolding is arranged in a cross of 20 m long and 20 m wide and is made of aluminium.  20 persons are allowed at a time. Care has been taken to install the structure non-invasively, with a minimum of branches cut, and the foundations merely placed on the ground.

The initial state of the experimental plot was characterised in relation to species distribution, litter layer thickness and apparent soil qualities.
