The funding for this project came from a European Maritime Fisheries Fund (EMFF) grant ENG_2578 to Natural England. The Marine Biological Association of the UK (Bishop Group) was contracted to carry out the survey, alongside Natural England staff. The presence/absence and an estimate of abundance was noted for a target list of 55 alien species and 57 native species. A Rapid Assessment Survey (RAS) methodology was used in the marinas/harbours and a similar adapted methodology on the intertidal shores. This method focuses primarily on fouling organisms which live attached to solid substrates. The majority of species were determined on site. Others by subsequent microscopy examination.

Shores: Method -Surveys undertaken at low Spring tides (usually below 0.8 m at Southampton). An area of low and mid-shore was allocated between the 3 surveyors. Each surveyor spent 1 hour searching the allocated area, by examining tidepools, underhangs, kelp holdfasts, artificial substrates etc. and turning boulders and cobbles. A further 15 minutes was spent on the upper shore examining boulders and the strandline. Marina/harbours: Method - Rapid Assessment Survey (RAS) - At each marina the available floating pontoons were allocated between the 3 surveyors. Each surveyor spent 1 hour searching their allocated area, examining and scraping pontoon sides, and examining any other substrates accessible from the surface e.g. ropes, buoys, fenders, kelps etc. Temperature and salinity were recorded at surface and at 2m depth at each marina. Secchi depth was also recorded to measure turbidity in the water column. All sites: For the 55 target alien species and 57 target native species presence/absence were noted and abundance estimated (using an abbreviated and adapted SACFORN scale where A=SA, F=CF, R=OR, N=N). The majority of species were determined on site. Any other potential alien species, unidentified specimens, those requiring microscopical examination for species confirmation, and specimens to substantiate significant findings were relaxed, preserved and examined later in the laboratory. The specimens were relaxed using menthol crystals and preserved in 70% IDA (Industrial Denatured Alcohol) in the field. Lab ID may involve dissection for confirmation of ID. This method focuses primarily on fouling organisms which live attached to solid substrates. Coordinates WGS 84 lat/long from camera GPS and Google Earth Pro aerial images.
