A 26 ha privately owned wooded gorge, 7km East of Lancaster. It is designated a SSSI as one of the best valleys in Lancashire for it’s bryophyte communities, including some approaching their extreme south-east range limit in Britain. There is a rich ground flora with scattered, mainly young deciduous trees but also some veterans and standing deadwood. Some deadwood is also left in-situ. There are large patches of Wild Garlic and the Ramsons, Hoverfly Portevinia maculata has been recorded in numbers but little invertebrate work has been done in the valley.
