NATURAL Resources Wales has contributed to new research that reveals Milford Haven’s unique seabed habitat.

Maerl beds are slow-growing accumulations of red algae that form complex underwater structures. These habitats play a vital role in marine ecosystems, providing shelter for a wide range of species and acting as significant stores of blue carbon - helping to mitigate climate change by capturing and storing carbon dioxide.

The new research reveals the distinct and ecologically important nature of the maerl beds in Milford Haven. The findings shed new light on how these fragile habitats can be better protected for the future.

Led by the University of Exeter, the study used Whole Genome Sequencing (WGS) to analyse maerl samples from Pembrokeshire to Cornwall.

The study found that the Milford Haven bed is genetically distinct from other populations, highlighting its uniqueness and the importance of site-specific conservation measures.

The authors of the research hope that using the data on genetic diversity could potentially identify those populations at greatest risk from environmental change and human activities.
