Ancient Farming Method Revives Rare Valley Lichens
2 Jan
Summary
- Rare lichens discovered thriving in Watendlath valley.
- Traditional tree pollarding practices support lichen growth.
- Temperate rainforest habitats are crucial for lichen survival.
A recent lichen survey in Watendlath, located in Cumbria's Borrowdale Valley, has revealed a vibrant ecosystem of rare lichens, with some species previously unrecorded in the area. This ecological success is largely credited to the continuation of traditional farming methods, particularly tree pollarding.
Carried out by the National Trust in collaboration with the British Lichen Society, the study emphasized how pollarding, a practice dating back to the 17th century, has significantly enhanced tree stability. This stability, in turn, has created an ideal environment for lichens to flourish.
The findings underscore the vital role of these historic agricultural techniques, alongside the preservation of the temperate rainforest habitats found in the valley's ancient woodlands, in sustaining the delicate lichen populations.
