Reptiles

Slow-worms and their neighbours: what is protected, and how to avoid killing one with a strimmer or a fork.

None of these have a Great Britain Red List assessment we could verify. We say “not assessed” rather than inventing a category — it is not the same as saying a species is doing fine.

• Not assessed

  Slow-worm

  Anguis fragilis

  Not a snake. A legless lizard with eyelids that blink — and the most useful thing living in your compost heap.
