The site was primarily arable farmland until 2009, when the Woodland Trust began planting over 600,000 trees.
It contains the 20-acre Langley Wood, which is an ancient woodland site dating back to at least 1600.
The forest project was supported by a major public fundraising appeal involving thousands of individual donors.
It hosts a dedicated memorial orchard featuring traditional fruit tree varieties.
The project includes the restoration of rare chalk grassland, a habitat essential for specific native flora and fauna.
Heartwood Forest was designed to connect with existing local woodlands to create a larger ecological corridor.
The site is largely managed through sustainable grazing to maintain meadow biodiversity.
Heartwood Forest is the largest continuous new native woodland in England, spanning 347 hectares near St Albans. Managed by the Woodland Trust, the site was converted from intensive arable farmland starting in 2009. It features a mix of broadleaf woodland, wildflower meadows, and ancient woodland remnants like Langley Wood. The forest includes three distinct waymarked walking trails of varying lengths. Significant efforts have been made to recreate rare habitats, including chalk grassland. The site is a key component of the Woodland Trust's effort to increase native tree cover. It is home to diverse wildlife, including tawny owls, kestrels, and multiple butterfly species. It serves as an accessible public space for recreation while focusing on long-term ecological restoration.

Wear waterproof footwear as the trails can become muddy, especially in the meadows during wetter seasons.
Check the Woodland Trust website for seasonal grazing maps to know which areas might have livestock present.
Bring binoculars if visiting during spring or early summer, as the birdlife and butterfly activity are high.
Attempting to walk the entire perimeter in one go without a map, as the site is much larger than it appears from the car park.
Keep dogs under control, especially in areas with grazing livestock; follow the 'leave no trace' principle.
