|Lowland Calcareous Grassland|
What are they?
They are found on shallow, well-draining lime-rich soils (soil pH above 7), generally overlying limestone or chalk in the warmer, drier areas of England.
How they are traditionally managed
They are typically managed as components of pastoral or mixed farming systems, supporting sheep, cattle or sometimes horses; a few examples are cut for hay.
Distribution in Bedfordshire
Chalk grasslands are largely found on the steep slopes of the Chiltern Hills in the south of the county. There are some small pockets in north Bedfordshire.
Distribution in Cambridgeshire
This habitat is found in a band that goes from the southeastern boundary of the county below the river Rhee and continues diagonally up, south of Cambridge, to eventually surround the outskirts of Newmarket.
Distribution in Northamptonshire
This habitat is found in association with the bands of calcareous grassland in the far northeast and southwest of the County. There are also areas where ironstone quarries have exposed the limestone below and a calcareous flora has then developed. Good examples include the Wildlife Trust reserves of Old Sulehay, Twywell Hills and Dales and Collyweston Quarries.
Species associated with them
The soils are infertile encouraging an intricate mixture of plants and animals. A careful search may reveal as many as 40 plants species in a square metre.
Just by spending a few minutes looking at your grassland, you will notice that it is composed of grasses and herbs of different shapes, sizes and colours. The presence of these species will give you an indication of the type of grassland you have.
- Flora associations
Quaking-grass, clustered bellflower, wild thyme, a range of orchids and the nationally rare pasqueflower and great pignut.
