Protecting Assynt’s Oyster Plant

29th July 2026

Andy Summers, Ranger describes the efforts he and local volunteers have taken recently to help save this species.

Oyster plant is one of Scotland’s northern coastal specialists, a species more at home on the cold shores of the North Atlantic and Arctic than further south. It is one of the species being supported through the Species on the Edge programme, which works to help some of Scotland’s rarest and most threatened wildlife.

Although there are other colonies along Scotland’s north and east coasts, the Clachtoll population is small and vulnerable. Sheep and rabbits find the fleshy leaves very tasty and can quickly eat the plants before they have a chance to flower and produce seed.

To help give the plants a better chance of survival, the High Life Highland Countryside Ranger Service have teamed up with Assynt Conservation Volunteers to build protective cages around the colony. Made from simple timber frames covered with wire mesh and secured among the beach stones, these structures are designed to keep sheep and rabbits away while allowing sunlight, rain and sea air to reach the plants. The cages blend into the rocky shoreline and provide just enough protection for the oyster plants to grow, flower and, hopefully, set seed.

The oyster plant is specially adapted to life on the coast, thriving on mobile shingle where few other plants can survive. Like many coastal species, it faces challenges from grazing, storms and changes to its habitat. Protecting small populations such as this helps preserve the unique wildlife that makes Assynt’s coastline so special.

We look forward to seeing this year’s plants flower and hope that, with a little help, this rare colony will continue to thrive for many years to come.
