Barcelona Biodiversity Atlas

A greener and naturalised city, where everyone can enjoy contact with nature close to home, enables us to achieve 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.

The Barcelona Biodiversity Atlas is a tool that helps us to display a large amount of information on these spaces. It is a map of the city of Barcelona divided up into 73 neighbourhoods that enables searches of the city’s trees, green-space plants, birds, butterflies and vertebrate animals among others, independently or together.

We can find out the scientific and common name of each species, see a short description and in some cases photographs or illustrations. Besides delving deeply into each of these layers, we can also explore the inter-relationship between them all and discover the total number of species that there are in each neighbourhood if we keep them all active.

All the information found in this Atlas is available to city residents in downloadable format, so this knowledge can be shared and new applications made from it.

It includes the following information:

  • Trees

    It features the more than 200,000 trees belonging to 487 species that are found in the city’s streets and parks. They can be selected one by one. It also states which of these trees are listed as trees of local interest.

  • Plants

    It includes over 1,400 species that can be found in the city’s gardens, squares and green plots. There are shrubs, climbers, creepers and some herbaceous plants (except for grasses and seasonal plants).

  • Birds

    You can find out which birds have been observed in the city based on a study classifying them according to UTM (Universal Transverse Mercator) squares.

  • Butterflies

    46 species found in the city based on an inventory conducted in certain parks to a citizen-science project based on the work of volunteers and in collaboration with benchmark institutions.

  • Vertebrates

    More than 30 species of mammals, amphibians and reptiles which are inventoried in certain green spaces.

  • Fish

    Over 100 different species of fish which live along our coast. Each beach has a space where you can check which species can be found there..

  • Naturalised ponds

    Plant species, vertebrates and invertebrates living in the city's most important naturalised ponds. A naturalised pond is one that is managed through fauna and flora, as an alternative to chemical management (chlorination).

  • Plant communities

    A plant community is defined as a group of plants living together on the same site, under specific environmental conditions and organised in a precise way in space and time. Some of these plant communities are known as CORINE habitats.

  • Degree of plant cover

    The normalised difference vegetation index (NDVI) is used for determining the quantity, quality and development of vegetation and creates an image that shows the city’s plant cover as seen from the sky.

  • Meadows

    The urban meadows that we find in the city’s green spaces. The tapestry of vegetation is made up of grasses, legumes, composts, cruciferous vegetables, plantains etc. They all make up a habitat for pollinators, birds and other beneficial fauna.

  • Grasslands

    The grasslands that we find in the city’s green spaces. The plant community is made up of grasses and other ruderal species. They all make up a habitat for pollinators, birds and other beneficial fauna.

  • Vegetation in tree beds

    A series of 65 spontaneous plant species we can find in the city’s tree pits. With highly decorative or discrete flowers, these act as a habitat for pollinators, birds and other beneficial fauna.

  • Planters

    Over 270 plant species we can find in plant tubs in the city, mainly small trees, bushes, perennials and some annual plants.

  • Crustaceans

    Series of the 89 species of crustaceans recorded at Barcelona's beaches.

  • Molluscs

    The nearly 250 species of molluscs recorded at Barcelona's beaches.
