How it fits into North Yorkshire wildlife

Earthworms are part of the unseen engine beneath North Yorkshire fields, gardens, pastures and woodland floors, improving soil structure wherever the ground stays alive and undisturbed.

How it interacts with the wider landscape

They recycle leaf litter into fertile soil and feed birds, hedgehogs, badgers and many other species, linking underground health to the wider food web.

Seasonal rhythm

They are most active near the surface in cool, damp conditions, especially through autumn, winter and spring.

Where to look and what to notice

Look for worm casts after rain, crumbly healthy soil and birds feeding where worm activity is high.
