St Kilda's sea caves in good condition

31 December 2018

St Kilda’s special reefs and sea caves are in good condition, a new report concludes.

The findings of a wide-reaching survey carried out in 2015 by a team of divers have now been published by NatureScot.

Almost 90 years after St Kilda’s last 36 residents were evacuated to the mainland, the islands remain vitally important for the wildlife they support.  

The World Heritage Site hosts huge seabird populations, including the world’s second largest colony of North Atlantic gannets, and the waters around St Kilda are part of Scotland’s Marine Protected Areas (MPA) network, designated a Special Area of Conservation (SAC) for their reefs and sea caves, which attract a wealth of spectacular sea life.

Crucial to the management of the MPA network, as with protected areas on land, is monitoring.

The purpose of the St Kilda survey was to judge the current condition of the site and to establish a baseline against which future assessments of its special features could be made.

Weather conditions severely interrupted the team’s plans but they managed to survey four caves at St Kilda, returning with valuable data and a collection of stunning photographs, which can be viewed and downloaded here (please credit NatureScot).

The full report on the survey, which found that the cave and reef features were in good condition, can be read here.
