Ten years ago the water-crowfoot was on the brink of extinction. But thanks to farmers and conservationists working together, it's now thriving on the West Wales coast.
The small, clover-like plant needs wild and marshy conditions to survive.
Mynydd Cilan is a heath to the south of Abersoch where it can now be found in abundance.
Farmer Emlyn Williams had sheep and horses grazing on the heath, and is pleased the crowfoot plant is doing well.
