Otters on the Lez: Understanding Biodiversity in the City

Otters are quietly returning to the Lez. The presence of this species speaks volumes about the condition of the Lez and biodiversity in the city. By combining signs of presence, camera traps, and environmental DNA, this lecture explores their habits, their movements, and what the species’ return reveals about the river’s evolution. An accessible way to discover the nature that flows through Montpellier every day, behind the scenes of a heavily trafficked river.
