This beautiful mountain plant, that once clung to the cliff edges in Eryri (Snowdonia) has successfully returned to the wild in Wales after becoming extinct in 1962. 

The trial reintroduction of Rosy Saxifrage Saxifraga rosacea, led by us, marks a special moment for nature recovery. The plants, which have been maintained in cultivation, have direct lineage to the 1962 specimens. 

It is now flowering at a location close to where it was last recorded in the wild – and there are plans in place to boost its numbers now the first trial has taken place.  

Why did it become extinct? 

The species was first recorded in Wales in 1796 by J.W.Griffith (Clark, 1900) and there are up to five records from the 19th century. In the 20th century, there are three records, all in Eryri. 

But, it is thought that Rosy Saxifrage slipped into extinction in Wales, primarily as a result of plant enthusiasts over collecting the species, particularly in the Victorian era. Atmospheric pollution is also considered to have played a role. Rosy Saxifrage is not a great competitor with stronger growing plants, so it was impacted by the nutrient enrichment of its favoured mountain habitat. 

The successful reintroduction has been led by our botanist Robbie Blackhall-Miles, Project Officer for the Tlysau Mynydd Eryri (Mountain Jewels of Eryri) conservation partnership project that aims to secure the futures of some of our rarest alpine plants and invertebrates in Wales. 

The outplanting took place on land cared for by the National Trust and in future months botanists will conduct surveys to establish places where it will be best to reintroduce the species fully to the wild.
