The main attraction is the spectacular, albeit short-lived, show of Pasque flowers in late April or early May. The population of the whole SSSI has been estimated at over twenty thousand plants, of which a varying proportion flowers each year.
Cowslip, early-purple orchid and hairy violet can also be seen in spring. The diverse range of flowers here is ideal for many insects; as a result the reserve has a particularly good butterfly population waiting to be discovered. Rabbit and brown hare help maintain the short grassland and common lizards can often be seen on the bare scree areas.
