Hatfield Forest National Nature Reserve

Hatfield Forest National Nature Reserve, located in Essex, England, spans 403.2 hectares and is designated as a Site of Special Scientific Interest and a Nature Conservation Review site. Owned and managed by the National Trust, it is the only remaining intact Royal Hunting Forest, dating back to the Norman kings. The reserve features a rich tapestry of habitats, including coppice woods, grasslands, and fen, providing a unique glimpse into medieval forest life. Wildlife enthusiasts can look forward to a variety of butterfly species, particularly in July when Meadow Browns, Marbled Whites, and Large Whites are most active, often peaking around 1:00 AM. Other notable species include the Gatekeeper and Silver-washed Fritillary, also best observed in July. For those interested in spring sightings, the Orange-tip butterfly can be spotted in May, while the Dark-edged Bee-fly appears in April, making these months ideal for a visit.
