Today is the International Day of Biodiversity. To make people more aware of the subject, UG staff member Douwe-Jan Schrale created an audio tour. This 25-minute tour – which starts at the jetty next to the Duisenberg pond – will take you across the Zernike campus, past five different pillars. There, the signs tell you more about the past, present, and future of nature at Zernike. UKrant went for a walk with Schrale.
