As part of the BIDELIN project, the first German-Czech student course "Green and Blue for the City - Capturing, Evaluating and Optimising Urban Ecosystem Services" was launched at the end of September 2017. During the following winter semester, students from both countries (Jan Evangelista Purkyně University in Ústí nad Labem, Anhalt University of Applied Science in Bernburg) will collect data of urban green spaces in Liberec and evaluate their value regarding ecosystem services (ESS). On the one hand, this work will contribute to the ongoing establishment of a catalogue of green spaces in Liberec, including the development of a tree cadastre. That will be a basis for developing targeted maintenance for urban green spaces in Liberec. On the other hand, this work provides useful information for assessing the value of green spaces (ESS) in Liberec within the BIDELIN project.
