What is it about?

There is a observation that urban tree species in cities are becoming similar. We compared species composition of urban forests from 38 cities worldwide and found that the similarity declined moving from local to the global scale.

Why is it important?

Our study provide evidence to support the idea that species composition of urban trees is still distinctive at the national, continental, and global scale. Biotic homogenization is more a local and regional scale phenomenon.

Perspectives

We used urban forest data to answer a basic ecological question. This shows the strength of interdisciplinay study.
