2010 NatureScot survey of Didemnum vexillum and other invasive species in South West Scotland

The first involved a series of rapid assessment survey events of those marinas and harbours thought to be most likely at risk from establishment (e.g. those in the Clyde). This was followed up by additional survey events of artificial and natural substrates in the vicinity of Largs Yacht Haven.

The results of this survey effort were to inform SNH’s policy for dealing with this species, as well as the wider UK policy for response. Twelve locations, including ten marinas and two harbours on the west coast of Scotland were surveyed for D. vexillum between 1 and 5 February 2010 following a similar method described in Ashton et al. (2006) and the method adopted by the Marine Biological Association UK in on-going surveys for this species in England (J. Bishop, pers. comm.).
