Greena Moor is 1 mile (1.5 km) south of the village of Week St Mary. From the A39, 5 miles (7.5 km) south of Bude, take the turning for Week St Mary. In Week St Mary turn right towards Week Green, then fork right. Access to the reserve is via a signed gate on a track off to the left, 0.75 mile (900 m) along this road.
Follow pathways across the fields. In the woodland a path is marked. The culm grassland is uneven under foot and can be very wet and muddy. Stout footwear is recommended.
Characteristic wildlife of this reserve
Culm grassland develops on poorly drained acid soils which stay wet even in the driest weather because of the rock structure below. The rock structure is made up of a mixture of shales, slates and sandstones laid down about 300 million years ago. Culm grassland is characterised by plants which have adapted to the dampness.
Meadow thistle and whorled caraway are two key species associated with the purple moor-grass and rushes that dominate this place. The meadow thistle is an elegant plant growing to almost three feet in height and with only the softest of prickles. In Cornwall, it is restricted almost entirely to the culm grasslands. Whorled caraway is a medium-height perennial with white, dome-shaped flowerheads. Its oblong leaves are finely divided with segments arranged in rings around the main leaf midrib.
A low mound on the stream's slopes may be the remains of a Bronze Age barrow. There are many barrows around this area.
The site is jointly owned and managed with Plantlife, the UK’s only membership organisation dedicated solely to the conservation of wild plants in their natural habitat.
The reserve was purchased in 1995 with grants from the National Heritage Memorial Fund and Esmée Fairbairn Charitable Trust.
