Özet

As a backbone of urban landscapes, urban green areas contain not only dozens of plant species, but also they are habitats for various species of birds, mammals, reptiles, amphibians and insects. The biodiversity of urban green areas influences numerous ecosystem services that are crucial to the well-being of urban dwellers. Quantifying biodiversity is an important step in understanding the relationship between biodiversity and ecosystem services. The most common measurement is species richness. In many studies changes in species richness have closely been tied to ecosystem functions. This study is intended to assess the biodiversity of Ege University Rectorship Garden located in a densely urbanized landscape of the Bornova district of the city of Izmir, Turkey. The garden is very rich in terms of floral diversity including old growth trees that provide valuable habitats for a wide variety of urban wildlife. Plant, avian and insect diversity of the garden were observed for five months between January and June of 2016. As a result 131 plants (tree and shrub), 25 birds, 24 insects, 2 amphibians, 2 slugs and 6 mushrooms species were observed and recorded. The Simpson’s index was used to analyze the biodiversity of the garden. The index results showed that the biodiversity of plants, birds and insects are high, while amphibians and slugs are low. On the other hand the biodiversity of mushrooms was in between.
