Barcelona Biodiversity Atlas

A greener city, where everyone can enjoy contact with nature close to home, means achieving a better quality of life. Green urban spaces provide the city with core values, at the same time as enhancing biodiversity and resilience when dealing with emerging challenges such as climate change.

In this sense, the Barcelona Biodiversity Atlas is the tool that helps us to view a large amount of information on these spaces.

The Atlas is a set of maps revealing some of the most relevant data on Barcelona’s biodiversity: parks, gardens, plant species that live there, street trees and the birds nesting in the city. Biodiversity is the variety of living organisms and ecosystems, as well as their interactions. This is why this atlas allows us to identify and localise the species and spaces separately, and also makes it possible to display them together in certain cases. This way, we're able to know which trees there are in a certain park or which birds nest there.

The information this map collects is:

  • The trees lining the city's streets.

    The more than 200,000 trees on the streets are presented here. They can be selected one by one, thus identifying the type of species, the common and scientific name and their main features. A selection by species can also be made to find out how many there are, as well as by neighbourhood.

  • The flora and vegetation of green spaces.

    The city’s main parks and gardens, as well as the large green spaces, can be located on the map (highlighted in dark green). These areas hold a significant wealth of flowers, trees, plants and other vegetation. By clicking on each green space, you can find out which plant species are there and you can learn the name and main features of each species. You can also select them and see how they're distributed throughout the rest of the city’s spaces. You can identify the total number of species by neighbourhood, as well as select by species to find out where they can be found.

  • The city's nesting birds

    By selecting this layer, you can find out which birds nest in the city’s trees based on a study classifying them according to UTM (Universal Transverse Mercator) squares. You can see which species live in neighbourhoods, as well as select by species to find out where they can be found. The common and scientific name of each species is also explained, along with a general description of their features. We’ll be able to identify the species with the illustration accompanying it.
