The implementation phase of the present study was conducted in 3 stages. In the first stage, the plant material used in the open green spaces in the urban center of Trabzon province was analyzed and plant inventory was investigated in these spaces to determine the species, characteristics and intended use of the plants. Thus, it was determined that 129 plant taxa were used in Trabzon public open green spaces. Forty-two taxa were indigenous to Turkey and 87 were exotic. It was identified that 34 were in the gymnosperm plant group and 95 were in angiosperm plant group. It was identified that 21 taxa were highly prevalent (5) in urban open green areas, 24 taxa were very prevalent (4), 35 taxa were moderately prevalent (3), 22 taxa were less prevalent (2), and 27 taxa were not prevalent (1). In the second stage, the objectives of planting and planting designs were investigated. It was determined that the plants were used for both aesthetic and functional purposes in these areas, but their aesthetic use was more common. In the third stage, the occupant satisfaction levels for the planting designs in these urban open green spaces were determined using a survey conducted with the occupants.
