Following last year’s theme of Root & Rise, we are left with the question: what makes a forest truly strong, resilient, and nourished?​ 

The answer lies beneath our feet, in mycelium.

​

Mycelium is an underground root-like network of entangled threads of fungi. It creates vast connections between plants and trees serving as a shared resource for nutrients, supporting growth as well as being a magnificent communication highway, sending signals and protecting one another. Our 2026 theme embodies this ethos – supporting connection between ourselves, those around us and nature, expanding from local action to global solidarity. A reminder that fundamentally, we are all nature. Mycelium teaches us that ecosystems flourish through collaboration, shared resources, and mutual care. Our communities can do the same. Facing climate challenges alone can feel overwhelming. But when we recognise how deeply intertwined we are, we also recognise our shared strength. Through collective action we can exchange ideas, re-energise, and cultivate meaningful change. Whether you’re beginning your sustainability journey or deeply rooted in climate work, join us to build a hopeful and connected community - forming our own vibrant, intertwined network.

Intertwined, we are stronger. Intertwined, we thrive.
