Habitat point records from 1990 NRA Swale Estuary survey

The 1990 Rivers Survey includes a quality classification of estuaries to provide a simple assessment of estuarine quality based on dissolved oxygen, aesthetic criteria, and simple biological observations. In an attempt to satisfy the requirements for the biological part of the classification, the sampling was carried out by the NRA Southern Region and samples passed on to Southampton University for infaunal and sediment analysis. Two 0.1m2 surface area grab samples were taken from each sublittoral site, and sieved through a 1mm screen. Two 50mm diameter cores were taken at each littoral site, and sieved through a 0.5mm screen. Each sample was preserved in 5-8% saline formaldehyde solution. Duplicate samples were taken for particle size and chemical analysis.

Habitat point records from 1991 NRA North Yorkshire and Humberside littoral rock survey

Biological surveys of seven rocky shores along Yorkshire's coastline were carried out in the spring and summer of 1991. Most of the shores had conservation value and were designated under the various categories Heritage Coast, SSSI and North York Moors National Park. Public access to all the sites was relatively easy. The topography of the shores was varied, although the presence of a wave cut platform was a fairly consistent feature. A large number of species were recorded during the surveys, including some which are considered to be rare or of a south western distribution. However the biological communities were fairly homogenous throughout the sites, differing largely in the extent and degree of algal cover and the density of Littorina littorea populations. The species richness of the sites appeared to correlate well with the complexity of the shore, wave exposure and turbidity. Some of the sites appeared to be mildly affected by raw sewage discharges, but none were as degraded as the rocky shores between Scalby Ness and Jackson's Bay since the construction of the Scarborough's short sea outfalls.

Habitat point records from 1981 Brathay Exploration Group Foula littoral survey

The intertidal flora and fauna of the rocky shores of the eastern coastline of Foula, Shetland Isles, were surveyed during July/August 1981. Ten primary shores were studied in detail : Da Rigs, North Boulder Beach, Ruscar, Head O'Da Taing, Trolli Geo, Head O'Da Baa, Dog Geo, Da Doon Banks, Surpeidle and Fisheads. Cover/abundance values were estimated fro the seaweeds and sedentary fauna present on the belt transects. Maps showing the accessibility, exposure and vulnerability to oil spillages were prepared for the island. Dogwhelk populations were sampled on each primary shore, length/aperture ratios calculated and related to wave exposure on each shore. The tidal range for the island is about 2m. Transects were set up from the low water mark to the top of the shore. Stations were located at 0.2m intervals up the shore. At each vertical station the abundance of the species present was recorded in a 5m * 0.2m quadrat. Shore profiles were also measured.

Habitat point records from 1982 Leicester Polytechnic Shetland Oil Terminal approaches survey

Thirty permanent transects established in 1978 and 1979, were surveyed. Individual stations were permanently marked at 25cm vertical intervals. Abundance scales from the report have been adapted from those in the report, to correspond to the MNCR abundance scale. The sites have been studied in 1978 (R650), 1979 (R282), 1980 (R1073), and 1982 (R530). Permanent transects have been set up to ensure precise relocation of the sites. The relative heights of the top stations of the transects in Whaal Firth were estimated by placing an observer at the top of each transect simultaneously. The position of the water line was noted, in relation to the nearest marked station at a predetermined time. It was assumed that tidal differences in the Firth were negligible to fix the top of each transect at an arbitrary reference level. The general survey methods used are based on those adopted by the Oil Pollution Control Unit (OPRU). The abundance scales and exposure rating scales are described in the 1979 report (R282), as are the sites and stations.

Habitat point records from 1990 SWT Orwell Estuary littoral survey

Data from this survey appears to be suspect. Angulus tenuis records are uncertain since they are recorded here for muddy sediments, but they are normally found in sand. Possible that they could be Abra tenuis (same abbrev). Suspect sites from this survey were excluded from 1994 data analysis for the SE estuaries. (TH 8.3.94)

Habitat point records from 1987 AWA Breydon Water littoral survey

The survey was carried out as an extension intensive surveys of the River Yare earlier in 1987. Also, public concern over the inadequacy of sewage disposal facilities in the Yarmouth area. At present, thirty outfalls discharge crude sewage into the lower River Bure, causing some organic enrichment to the lower River Bure. The survey was carried out in the first week in June 1987. Eight sites were sampled with a cylindrical corer (15cms diam by 20cms deep). Three replicates were taken from the mid horizontal distance point between high and low tides. Cores were taken soon after low water on each occassion. A sub sample from each sample was taken for sediment analysis, the remainder was sieved through a 500 micron sieve. The survey suggests sewage enrichment of the lower estuary increases the productivity but does not adversely affect the species diversity. It was also postulated that much of the mercury discharged through the Norwich sewage works during the previous twenty years has accumulated in the sediments of Breydon Water. The estuary was found to support a healthy, but undiverse invertebrate fauna. The lack of diversity was thought to be due to the homogeneity of the sediment types and the lack of extremes of salinity within Breydon Water. Breydon Water satisfied the biological, chemical, and aesthetic criteria for a class A estuary under the UK Estuarine Classification Scheme. Breydon Water is important as an over-wintering ground for waders, wildfowl and gulls.

Habitat point records from 1985 AWA River Stour littoral survey

The survey was done as a pilot study for the future monitoring of the area in a three year rolling programme. A comparison was made with an earlier survey by the Institute of Terrestrial Ecology (Kay and Knights 1975), for any changes in the benthic ecology. Sampling was undertaken from a boat in August 1985, with the exception of sites 1-5, 40 and 41 which were accessed by foot from the shore. Samples were taken with a corer of 6.5cm internal diameter, 15cm deep and a surface area of 33.2cm. Three replicates were taken at each site resulting in an area of 99.5cmsq. Each sample was put through a 0.5mm seive. The survey concluded that the condition of the macroinvertebrate benthos compares favourably with that of other estuaries in the area, and classes the river as `clean`. The study recomended monitoring of the apparent shift from a mollusc dominated community to a polychaete dominated community. No data was recorded from sites 20 and 23 in the survey report.
