England’s 330-acre wheat farm turned wild; 5,290 butterflies counted in 2 years

Halnaker Hill Farm in West Sussex has experienced a remarkable surge in butterfly populations thanks to dedicated habitat restoration initiatives. In the spring of 2026, surveys noted 5,290 butterflies representing 28 different species, including some that are quite rare. This ecological project has fostered a rich variety of habitats that not only attract butterflies but also support bird life and other insects.
