Scientists from the University of Exeter are examining the genetic connectivity of pink sea fans collected from Alderney's south-west coast.
Dr Mel Broadhurst from the Alderney Wildlife Trust says by spring 2025 we will know the origins of Alderney's colourful coral.
"Research such as this allows us to identify how closely our seas are connected.
The scientists will be able to see how oceanographic processes, like tidal currents and winds, help those populations sustain, in terms of their genetic similarity between the UK or Europe."
Last month, visiting scientists scuba-dived at Braye Rock, Grois Rock and Les Noires Pute to gather small samples of the warty looking soft corals.
Dr Broadhurst says unfortunately the International Union for Conservation of Nature classifies this species as ‘vulnerable’ at a global level.
"We see it as a really important species.
It actually acts as a habit, it sustains tiny little creatures such as an endemic sea anemone and sea slug - they will only live on those sea fans.
Pink sea fans are particularly under-recorded across Alderney, so gaining new information on this important marine species is paramount."
