Özet

Outdoor recreation is an important issue for people living in areas where they face problems caused by harsh climatic features like the city of Erzurum. The aim of this study was to determine the favourable features of tree species, which can grow in the city, for human bioclimatic comfort conditions. For this aim, measurements of climatic elements (temperature, humidity, and wind) were carried out under different tree canopies in the Ataturk University Ata Botanic Garden in July and August 2008. For the calculation of bioclimatic conditions, one of the most widely used indices, THI (Thermo hygrometric Index) was used based solely on the data of clear and calm days during the measurement period. From the results of the study, it was found that the canopy of Scotch pine trees can provide the most comfortable environment by increasing human thermal condition by 5.1 %, followed by Silver birch trees by 3.8 % which increased human thermal condition when compared to open space while mixed canopy did not give the respective results. Some suggestions about the use of plant materials in recreational areas are presented.
