Ancient Woodland.
Woodland continuously present since 1600 — an irreplaceable habitat. NPPF gives it strong protection: loss or deterioration should be refused unless there are wholly exceptional reasons and a suitable mitigation strategy.
- Schemes that retain a generous buffer
- No direct loss or canopy/root harm
- Positive woodland management & access
- Biodiversity net gain alongside protection
- Development close to the woodland edge
- Drainage / hydrology changes nearby
- Increased recreational pressure
- Lighting affecting the habitat
- Any direct loss of ancient woodland
- Loss of ancient or veteran trees
- Deterioration of the habitat
- Fragmentation of woodland
Ancient woodland is land that has been continuously wooded since at least 1600. It is recognised as an irreplaceable habitat: NPPF states development resulting in its loss or deterioration should be refused unless there are wholly exceptional reasons and a suitable compensation strategy exists. Ancient and veteran trees are protected on the same basis.
Standing advice from Natural England and the Forestry Commission recommends a buffer (typically at least 15m) between development and ancient woodland to avoid harm from root damage, canopy works, drainage and recreation pressure. As an irreplaceable habitat, compensation is rarely sufficient — avoidance is the expectation.
Ancient woodland is the strongest ecological constraint short of a statutory site: as an irreplaceable habitat, the realistic strategy is complete avoidance with a generous buffer, not mitigation.
Refusals and dismissed appeals cluster where schemes pressed too close to the edge. Hold the buffer, follow standing advice, and the rest of the scheme is judged on its own merits.
How schemes actually fare inside this designation — approval rates, appeal survival, which authorities apply it hardest — needs the designation joined to the decision record. That join isn’t built, so those figures aren’t published here. We won’t estimate them.
The Atlas maps the ancient woodland inventory against INSPIRE parcels. Check whether your site abuts irreplaceable habitat before fixing a layout.
