Strapwort Corrigiola litoralis is a critically endangered plant growing on the shore of Lower Ley. Slapton is the only place in the Britain where it grows because Britain is at the northern extent of its range.
Since 1978 we have recorded the total numbers of plants in August, showing a decreasing population. In 1991 English Nature initiated a 3 year Species Recovery Programme with the aims to:
- Establish four self sustaining populations.
- Re-establish Cattle Grazing.
- Control water levels in the lagoon.
In 2006 Whitley Wildlife Conservation Trust and FSC created a new reintroduction programme, collecting seeds from Slapton Ley, propagating plants at Paignton Zoo and translocation at Slapton Ley.
