Stoepplantjes: the hidden garden in the cracks under our feet

My main research subjects are urban flora and citizen science. I am working on a citizen science project called 'Stoepplantjes' where we map out where and what different pavement plants grow in cities and towns, together with citizens. With this data I'd like to eventually see if we can advice municipalities on how to improve urban nature and biodiversity in their villages and cities. Additionally, we want to see if participants of the Stoepplantjes project will develop more attention for urban flora.

To touch or not to touch… the plastic soup of Leiden

From diaries and condoms to COVID-19 self-tests and fish hooks, Liselotte Rambonnet researches the litter floating in the canals of Leiden together with amazing volunteers during weekly Plastic Spotter clean-ups. Liselotte will tell you everything about their clean-up adventures from their most expensive find to the current sources of local pollution they are tackling. This activistic biologist successfully forced the city of Leiden to switch from single-use cups to reusable deposit cups with her initiative Canal Cups.
