 Site Description The Exmoor IPA is a patchwork of habitats. Exmoor heath is a representative of wet upland heathland, and supports rare vascular plants whilst Exmoor cliffs support a vast diversity of vascular plants. This IPA also contains one of the largest and most extensive old sessile oak woodlands in the UK. The IPA is is largely owned and protected by Exmoor National Park Authority and has been managed for over 100 years.

 Botanical Significance Noted for bryophyte and habitat interest
