The Athens’ team is continuing its work to strengthen urban nature monitoring through an ongoing campaign for the city’s trees registry, inviting citizens and visitors to contribute valuable data via the Trees app.
As part of this campaign, The Trees App for Athens has been enhanced with advanced functionalities designed to evaluate and monitor aboveground biomass, carbon storage, and CO₂ sequestration in urban trees. These new functionalities are based on the research study of PhD candidate Magdalini Dapsopoulou, a forester working within the Municipality of Athens Greening Department.
The study, Dapsopoulou, M., & Zianis, D. (2025). Biomass Allometries for Urban Trees: A Case Study in Athens, Greece. Forests, 16(3), 466. https://doi.org/10.3390/f16030466 was conducted as part of the thesis, “Urban green, carbon storage and bioenergy production: The case of the Municipality of Athens”, carried out in the Department of Forestry and Natural Environment Management, School of Plant Sciences, Agricultural University of Athens.
The research developed a scientific method for estimating the biomass of urban trees using simple measurements such as tree height and trunk diameter. By integrating this model into digital urban forestry tools, Athens can better understand how trees contribute to carbon storage, climate resilience, and the overall environmental health of the city.
The integration of this scientific model into digital urban forestry tools directly supports the objectives of Urban ReLeaf by promoting transparent, data-driven urban governance and strengthening climate resilience planning.
Through this work, Athens demonstrates how local research and accessible environmental data can contribute to more sustainable urban planning approaches that may also support other European cities within the Urban ReLeaf framework.
