The green barrier derives from the afforestation plan for Hoia-Baciu Natural Area, and it serves multiple structural purposes. The northern and north-eastern flanks demarcate the undesired uphill progression of the Industrial Zone Cluj West. The southern and south-eastern flanks produce a necessary enclosure to the meadows at the top of the hill. For the Ethnographic Parc, the barrier cancels out the visual juxtaposition with a discording urban vicinity. For small forest animals, the barrier links Tăietura Turcului to a continuous 8,50 km corridor all the way to Saloș and Bogoșir Forests, at its west end.

Local, coniferous species of the largest size were chosen to ensure a rich, dark green curtain during winter, when people visit the area for sleighing in Hoia and for Christmas traditions at the Ethnographic Parc. Conifers are a familiar sight at the Ethnographic Park, being planted next to many traditional homesteads to depict their native mountain landscape from Apuseni and Rodnei areas.
