Metadata: 2014 Scottish Natural Heritage (SNH) Loch Moidart, Lochaber Site Check survey of intertidal sediment flats
Abstract:
The main purpose of this study was to carry out a Site Check survey (rapid assessment technique - brief form of site condition monitoring) of the intertidal sediment flats of Loch Moidart and Shiel Woods SAC, following the inauguration of site condition monitoring in 2003, to facilitate assessment of the condition of the sediment flat habitats. Site Check of the sediment flats involved checking the presence and sequence of biotopes along the five transects surveyed in 2003. This involved recording data at the 16 relocatable stations along each transect. The sediment type and depth of the anaerobic layer was recorded and the habitat photographed using stills and video cameras. Biota was assessed by digging over areas of sediment and recording abundance recorded on the SACFOR scale. A subsidiary aim of the survey work was to produce a biotope map of the sediment flats. This involved supplementing the Site Check data by walking over the area recording the nature of the substratum and conspicuous biota observed.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Data collection for the Site Check survey took place at a series of relocatable stations along transects, surveyed in 2003, that reflected the biological and environmental diversity of the intertidal sediment flats in the SAC. The 5 transects (MA to ME), which included a total of 16 sample stations, were laid out perpendicular to the shore and to low water channels at the seaward end. Each station lay within a perceived habitat zone identified from the physical appearance and biological surface features. The positions of both stations and zone boundaries were recorded. At each station, a record of any surfical biota was made by photographing five replicate randomly placed 0.25 m2 quadrats and noting incidental visual records. In addition, approximately 1 m2 of sediment was dug-over using a spade, to a depth of about 30 cm to check for the presence of conspicuous infauna and estimates of their density made using the SACFOR scale. Smaller infauna was similarly recorded but sampled by sieving, using a 1 mm mesh, an area of sediment of c. 250 cm2. All transects and stations had their positions fixed by hand-held differential GPS using WGS84 datum. For biotope mapping of the sediment flats a wireframe map (of putative habitat polygons) with aerial imagery was available in the field on a series of laminated sheets. It was also uploaded to a large-screen, sunlight-readable, differential GPS receiver (Garmin Montana 600). One team of 2 - 3 recorders surveyed the area, largely within three hours either side of low water springs by walking each of the polygons where possible, employing target notes at fixed locations to record the characteristics of the habitat. Where appropriate, descriptions of habitats between target point positions were also recorded, with the surveyors' track continuously recorded by a GPS data logger. Field data collected to aid subsequent biotope identification included physical habitat characteristics, biotic surface features and the infauna revealed by digging over an area of c. 1 m2, with retention of specimens where necessary for laboratory identification. In many cases it was also felt necessary to supplement dig-over material by sieving sediment from an area of c. 250 cm2 using a 1 mm mesh. Field observations were supplemented by still and video photography. The wireframe laminates were used for sketching the distribution of perceived habitats in the field and to aid investigation of conspicuous features on the aerial imagery. In general, biotope ascription to areas was deferred until the results of infaunal analysis were available and, in view of the limited information available at individual target sites, biotopes were assigned to areas, rather than individual sites. The biotope mapping GIS project employed the OSGB 1936 coordinate system and British National Grid projection. |
