Łódź Tree Map with a New Function – a project by the UniLodz Faculty of Geographical Sciences Under the Science Hub – UNIC Edition

A team led by Dr Patrycja Grzyś and dr hab. Paulina Tobiasz-Lis, Associate Professor at the Faculty of Geographical Sciences at the University of Lodz, has been implementing a project as part of the UniLodz Science Hub platform. Its goal is to strengthen the role of urban greenery in adapting to climate change and improve the health of residents of post-industrial cities. The project combines the expertise of the University of Lodz and University College Cork (School of Public Health) within the UNIC Alliance. The Socially Engaged Association, the creator and maintainer of the Łódź Tree Map is the local partner.

“Greenery as a Tool for Adaptation: Socially Rooted Innovations in UNIC Cities” Project

The main goal of the project is to design and implement a new functionality in the Łódź Tree Map application – a module enabling the estimation of the compensatory value of urban trees. Łódź Tree Map is a participatory digital platform launched in 2022, inspired by New York's NYC Street Tree Map. Over the past three years, volunteers have inventoried nearly 100,000 trees in Łódź, collecting data on their species, height, health status and growing conditions. The new module will allow for the determination of not only the replacement value of trees, but above all, their importance to the well-being and health of residents – a step towards a tool that will have a real impact on the management of green spaces in the city.

The project also includes comparative and educational activities in collaboration with University College Cork, School of Public Health. The Cork partners bring a public health perspective and the Healthy Cities concept to the project, which emphasises the link between access to urban greenery and the quality of life and health of local communities. Łódź and Cork are two cities with different cultural and institutional contexts, yet face similar challenges: how can greenery be protected and developed in an urbanized, post-industrial urban fabric? Joint meetings and exchanges of experiences between students and researchers from both universities will allow for a diverse perspective on these challenges.

The project fits into the broader context of the Socially Engaged Association, which has been engaging Łódź residents for years in active care for urban greenery and monitoring the condition of trees. Data collected by the Łódź Tree Map demonstrates the serious challenge posed by the condition of Łódź's greenery: nearly one in five surveyed street trees was assessed as being in average or poor condition and trees growing in concrete substrates fare significantly worse in health statistics than others. A new module within the application aims to help translate this knowledge into concrete arguments – both scientific and social – for better tree protection in the city.
