Sea buckthorn removal at Murlough
A five-year project is currently taking place to remove much of the invasive sea buckthorn at Murlough. Partially funded by NIEA, the team is on track to remove 4 hectares of it over the next few years.
What is sea buckthorn?
The sea buckthorn plant is known for its brightly coloured berries, giving early winter a splash of bright orange.
Used both medicinally and cosmetically, the berries are edible and regarded as a superfood due to their rich nutritional content.
A non-native plant
Not native to Ireland, the plant was introduced to Murlough by the Downshire family in the 1890s to help stabilise the dunes. Its fast-growing root system holds the dunes in place and is often used for anti-desertification purposes. It grows voraciously, spreading quickly even in poor soil. It grows especially well in coastal environments like Murlough.
Tough and armed with thorns
Although it has served its intended purpose, as a non-native plant it hinders the natural ebb and flow of the sand. During storms it can lead to large swathes of the dune being washed away, leaving behind a sheer cliff rather than a smooth slope. It grows in a tough, thorny thicket and prevents any native plants from surviving underneath.
Sea buckthorn creates shade
The only plant which survives the shady conditions at Murlough is sycamore, which in turn grows quickly and shades out the sea buckthorn. Sycamore woodland now stands where once had been sand dune.
Work in progress
The five-year project is now heading into its third year. Partially funded by NIEA and with lots of hard work by the team, vast amounts of the plant have already been cleared. The work takes place mostly during the winter before the birds' nesting season, and any regrowth is carefully monitored throughout the year.
Returning the natural habitat
The project has opened up new sections of the beach and the hope is that it will encourage the natural ‘yellow dune’ to flourish and the return of our special native habitat to these areas.
The dune system at Murlough is estimated at being up to 6,000 years old. Discover the history of the dunes, and how Murlough came to be Ireland’s first national nature reserve.
