Location and habitat
The site is in the village of Clearwell, which is on the western edge of the Forest of Dean and in west Gloucestershire. The Old Bow and Old Ham Mines SSSI is close-by. Tudor Farm Bank is considered to be the biggest remaining grassland site of its type, and is near the western-most edge of the natural distribution. It lies on a small escarpment and is south-west facing. It is on Carboniferous limestones. The site is designated because of its calcarous grassland and the species it supports. These limestones surround the Forest of Dean. Neutral grassland areas are present at the bottom of the slope and to the west. There are limestone outcrops
Flora
The grassland species include sheep's fescue, quaking grass and glaucous sedge. Herbs include rock-rose, restharrow, Carline thistle, common milkwort and dwarf thistle, yellow-wort, fairy flax, wild thyme and large thyme (Thymus pulegioides). Thyme and common knapweed are plentiful, which is usual for this kind of grassland.
The neutral grassland areas support crested dog's-tail, common knapweed, red fescue, yellow oat-grass, meadow vetchling, common bird's-foot-trefoil, yarrow and ribwort.
Scrub has developed in an area of the site which supports a range of species such as hawthorn, blackthorn, bramble, dog's mercury, cuckoo-pint, hart's-tongue fern and primrose. The area supports a rarity being stinking hellebore.
Fauna
The habitat and flora encourages a good range of invertebrates and butterflies include large skipper, ringlet, marbled white and common blue. The yellow meadow ant thrives on this bank.
