Abstract :

Background and Objectives:Calculation of biodiversity indices of urban birds in Tehran in order to better understand the environmental conditions and improve or modify seems necessary. The aim of this study was to calculate the indicators of richness, biodiversity and bird uniformity in Tehran as a case study in the parks of the city, Mellat, Jamshidia and Ghaem.Methods: In this study, the birds were recorded by point counting and the indices were calculated using Ecological Methodology software.Finding: A total of 3723 birds were observed in 40 species of 8 orders and 19 families. 75% of all recorded species belonged to Passeriformes and among them the number of House Sparrows. Although the Ghaem park had the largest area among studied parks, had the least species richness and diversity and was the most abundance. The Shar park the oldest Tehran urban park located in the densely populated of the city, with the highest richness and species diversity and the lowest abundance, compared to the other parks.Discussion and Conclusion: The birds registered in the studied parks were mostly owned by the Passeriformes and half of them were native to Tehran. The area of the above boats does not necessarily mean that the birds are more diverse. According to the findings gathered in Park-e- Shahr located in the city center, We found out despite the presence of dense texture, the suitable space existed, attraction and capturing the birds were observed. The results of this research can provide an opportunity to study the factors affecting urban biodiversity indices and help environmental researchers, managers and urban planners to design a suitable green space to protect biodiversity and attract birds as one of the health habitat indicators and improve citizen’s quality of life.
