What happened: A recent survey found 264 pairs of Dartford warblers on RSPB reserves in 2025, marking a 44% increase over five years. This bird species nearly disappeared from England in the 1960s.
Why it matters:
- The rise indicates successful conservation efforts for a once critically endangered bird.
- Heathland ecosystems benefit from the return of this native species.
MNN Take: The Dartford warbler's recovery shows how targeted habitat protection and management can help restore vulnerable wildlife populations over time.
