Cities need to become greener, more biodiverse, and climate-resilient. However, many organisms that are vital for the functioning of urban green spaces and the wellbeing of urban citizens remain largely unknown.

This hidden biodiversity—including bacteria, fungi, soil animals, algae, mosses, lichens, and pavement plants—is being researched and brought to the attention of urban residents through the HiddenBiodiversity project.

Research on lichens and lryophytes

At the Hortus botanicus Leiden, our research specifically focuses on two fascinating, yet often overlooked groups: lichens and bryophytes (mosses). We explore patterns in their distribution and examine overall biodiversity. Additionally, we investigate how these species respond to and adapt within the urban environment, with a particular focus on the urban heat island effect.

By uncovering and highlighting this hidden biodiversity, we aim to raise awareness about its significance and the critical role it plays in maintaining the ecological balance and enhancing the urban environment.
