We’re joined by Professor Nigel Willby and Patrick Cook, an ecologist and PhD student, from the University of Stirling, to explore the species group at the base of any food chain: plants 🌱

Nigel and Patrick help us unpack:

🌿 What long-term research from Bamff reveals about how beaver activity boosts plant diversity, including a 46% increase in species richness and dramatic rises in habitat “messiness”.

🌿 How beavers create dynamic, ever-changing landscapes through felling, browsing, digging and even dredging hidden seed banks.

🌿 The pollinator plants that thrive in beaver wetlands, from water mint to creeping thistle.

🌿 How the risk of beaver activity compares to human influence on the spread of invasive and non-native plant species.

We also look at the willow–beaver “partnership”, the curious items tucked into beaver dams and Patrick’s research, which found nutrient-rich, decaying plant materials in beaver canals create a 119% increase in hoverflies.
