Metadata: 2015 Scottish Natural Heritage (SNH) Loch Paible, North Uist sediment flats site condition monitoring and biotope mapping survey
Abstract:
The purpose of this study was to carry out site condition monitoring (SCM) of the mudflat feature within Loch Paible and biotope mapping of the sedimentary flats. SCM was inaugurated at this site in 2004, which provided a baseline for the current study. The principle aims were to: (1) identify any deterioration in the condition of the mudflat feature; and (2) to form a judgement on its current condition. The approach taken to achieve this aim was to resurvey two representative, relocatable transects established in 2004.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The Site Condition Monitoring (SCM) methodology of this survey followed that employed in the 2004 baseline survey. Two representative, relocatable transects established in 2004 were re-surveyed with a total of 6 stations, representing perceived different habitat zones. Transects were relocated using dGPS. Zone boundaries from 2004 were also relocated and marked, as were any perceived changes in these boundaries. The vertical height of stations and zone boundaries was determined relative to the permanent transect marker at the head of the transect using a surveyorâ??s level. As the transect markers had been leveled to the water's edge in 2004, all heights could be expressed in relation to chart datum. The surveyorâ??s level was also employed to measure the horizontal distances of stations and boundaries from the transect marker. Still photos were taken at many of these sites and video footage at a few. Biotope mapping of the sediment flats was also carried out by supplementing the SCM data by walking over the area recording the nature of the substratum and conspicuous biota observed in the form of target notes at fixed positions. Note: Although the notified sediment flat feature for the Balranald Bog and Loch nam Feithean SSSI is mudflats, a mudflat biotope graded into a sandflat biotope along one of the transects and so both habitat types were considered to fall within the remit of this 2015 survey work. At each station, eight cores of 10.3 cm diameter and 15 cm depth were taken for analysis of the infauna, along with a single core of 3.4 cm diameter and 20 cm depth for particle size analysis (PSA). The eight infaunal cores were pooled in a single bucket and sieved on site using a 1 mm mesh. These samples were preserved in 5% buffered formalin in seawater until analysis. The PSA samples were transferred from the core to labelled bottles and kept in these until analysis. At one station on each transect four replicate samples for infaunal analysis were taken, the stations being the same as those similarly selected for the baseline survey in 2004. Each sample consisted of eight pooled cores, as above. At each station a record was made of any surficial biota by photographing five replicate, randomly placed 0.25 m2 quadrats, and by 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 any infauna which might not have been effectively sampled by the cores (e.g. larger bivalves and polychaetes), and estimates of their density made using the SACFOR semi-quantitative scale. Specimens from this dig-over were noted and some retained for confirmation of identity. The macrobenthos from the core samples was sorted, identified and counted by Fugro EMU Ltd. (Edinburgh). All other faunalk samples were processed by Colin Moore. |
