Through its dimensions and value, the tree often remains the central element of the urban plant-life palette.

Its protection is one AREA's track record know-hows. Sheltering the trunk of a tree from dense urban areas is the role of the guard whereas the stakes help the tree in its first years of growth. As a pioneer, AREA imagined, as of its creation, a system associating both functions: the guard plus stake system was born. By directly fixing these systems on the grates, at the foot, the forces undergone by the tree are thus transmitted to the ground through the intermediary of the rigid guard/grate/frame/ground bond. The trunk being perfectly maintained, the roots develop better and quicker; and these amenities can be reused for other plantations.
