**Slow Worm / Kopparorm / Slow Worm**

## FAQs

- **What role does coarse woody debris (CWD) play in the boreal habitat of the slow worm?**: The slow worm is a semi-fossorial lizard highly dependent on structural complexity in the forest. Deadwood in various stages of decay provides a moist, temperature-buffered microclimate and is rich in detritivores like slugs and earthworms, its primary prey.
- **How does modern forestry in Scandinavia affect Anguis fragilis populations?**: Clearcutting, the removal of deadwood, and the conversion of mixed forests into monocultures (Pinus sylvestris or Picea abies) destroy essential microhabitats. The lack of structurally diverse forest edges and woodland key habitats reduces prey density and increases predation risk.
