  • This map was produced as part of the site selection process for the Greater Thames Estuary AoS. It aimed to characterise the habitat features of the AoS, and to identify the areas of Annex I habitat present.

  • Details the merged substrate maps produced within the proposed Skerries and Causeway Proposed Marine SAC.

  • Outputs produced as part of the Outer Thames Estuary Regional Environmental Characterisation on behalf of the Marine Aggregate Levy Sustainability Fund. Data available to download from www.thamesrecgis.org.uk

  • Aerial imagery and OS mapping was digitised to produce baseline maps of biotope boundaries. The maps were annotated in the field to identify biotopes and boundaries as well as significant features. In addition, intertidal sediment cores were taken at 16 stations (0.01m2 cores 3 replicates at each station) distributed throughout the Cumbria Coast rMCZ at the low, mid and high shore, in order to assess the benthic species present, along with an additional sample for Particle Size Analysis. Samples were sieved over a 0.5mm sieve. Sediment scrape samples were also taken at 4 stations at the midshore for Tributyl tin, heavy metal and organic contaminant analysis. The Phase II quantitative survey of intertidal rocky reefs comprised of 9 quadrat sites per transect with 3 replicate quadrats at each low, mid and upper shore zone or the main biotope present. Percentage cover of species present within each 0.25m2 quadrat was recorded. The methods used for data collection and processing followed protocols and standards for biotope mapping and sampling. MEDIN Data Guideline for sediment sampling by grab or core for benthos.

  • Hythe Bay rMCZ verification survey conducted by CEFAS and Environment Agency on behalf of DEFRA. The purpose of the study was to produce an updated habitat map to inform on the presence of Broad Scale Habitats, Habitat FOCI and estimate spatial extent within the rMCZ, as well as providing evidence of the presence of Species FOCI. The study comprised of acoustic data acquisition and interpretation followed by ground truthing. Ground truthing was conducted using a Hamon Grab.

  • THIS was was converted to EUNIS L3 by NE and forms the data NE provided to the JNCC as part of the MCZ project – Tranche 1. A MESH Confidence Score of 86 was assigned to the dataset based on the information given in the reports supporting the GIS.

  • A Natural England commissioned verification survey of intertidal rocky reef within the Torbay rMCZ. Phase I Biotope mapping was carried out across the rMCZ for broad scale habitats. Phase II survey comprised of a quantitative quadrat survey to provide information on the benthic infaunal assemblages, with percentage cover of species present within each quadrat being recorded. The data was used to produce a EUNIS Level 3 boradscale habitat map of the Torbay rMCZ.

  • A Natural England commissioned verification survey of both intertidal sediments and intertidal rocky reef within the Padstow Bay and Surrounds rMCZ. Phase I Biotope mapping was carried out across the rMCZ for broad scale habitats. Phase II infaunal sediment sampling was carried out to provide information on the benthic infaunal assemblages and particle size distribution of the study sites by means of core sampling. Sediment surface scrapes were obtained for heavy metals and organic contaminants analysis. Phase II quantitative survey of intertidal rocky reefs comprised of a quadrat survey with percentage cover of species present within each quadrat being recorded. The data was used to produce a EUNIS Level 3 boradscale habitat map of the Padstow Bay and Surrounds rMCZ.

  • A Natural England commissioned verification survey. Littoral biotope survey and condition assessment of the Lynher Estuary SSSI. The purpose of the study was to establish a physical and biological baseline dataset to facilitate an assessment of favourable condition status of littoral sediment habitats of the SSSI site, as well as identifying species and biotopes that are representative and/or notable within the Lynher Estuary, in particular the distribution and extent of saltmarsh. The study comprised of Phase I and Phase II surveys. Phase I comprised of groundtruthing aerial photography to establish the distribution and extent of intertidal biotopes, interest features and species. Followed by Phase II; detailed descriptions of biotopes present , flora and fauna species list and abundance, as well as sediment characteristics by means of box-core sampling. The data was used to produce a detailed biotope map of the Lynher Estuary.
