Rare Purple Emperor Butterfly Sees Comeback in Sussex
What Happened
On July 1, 2025, ecologists at Knepp recorded an unprecedented 283 Purple Emperor butterflies in a single day—the highest daily count ever there.
This marks the most notable peak yet in a species recovery trajectory that started when rewilding began in 2001.
What Is Good About It
Ecological restoration success: The resurgence confirms that restoring sallow scrub and oak woodland mosaics provides ideal conditions for this rare species to thrive.
Expanded biodiversity: Alongside Purple Emperors, other woodland species like nightingales, swifts, and additional butterfly varieties have flourished too.
Community-backed conservation: Knepp’s two-decade transformation highlights how long-term, process-led rewilding can revive entire ecosystems.
Why It Leads to Positivity
Nature’s recovery power: Demonstrates how giving land a chance to wildheal can rapidly restore endangered species.
Model for conservation: Provides a blueprint for global rewilding efforts, showing measurable benefits over time.
Inspires action: Tangible successes like this fuel public support for habitat restoration and ecological investment.
