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.
