Urban Greenery, Climate Change, and Biodiversity in Barcelona

This project aims to evaluate the adaptability of two new tree species (Zelkova serrata and Pistacia chinensis) to the conditions of Barcelona and their potential to provide essential ecosystem services, with the goal of promoting their planting to enhance the resilience of urban greenery to future climatic conditions.

 

The new climatic reality driven by global warming means that urban trees will face increasingly adverse conditions, potentially compromising their ability to provide essential environmental services (such as shade or recreational spaces) and even their survival. This reality will require a reassessment of tree species selection, as well as planting and maintenance methods in urban environments. All these changes should be based on decisions supported by scientific knowledge and experimental data that validate their applicability.

The project is the result of an agreement between the Fondazione Capellino, the Barcelona City Council, and CREAF as part of the actions under Barcelona’s Nature Plan. Twenty-five specimens of each of these species will be planted in four city gardens and in the municipal nursery. Specialized sensors will be installed on these specimens to provide detailed data on their condition throughout the four years of the project. These sensors will continuously monitor trunk diameter growth, ambient temperature and humidity, air quality, and soil moisture. The collected data will be analyzed to assess the adaptability of the studied species to various urban conditions and determine their suitability for future planting in Barcelona's parks and gardens.
