This project is focused on producing a series of Conceptual Ecological Models (CEMs) for the marine habitat ‘Shallow Sublittoral Mixed Sediments’.
The aim of this report is to determine whether the inshore areas of Belfast Lough, or a part thereof, meet the UK SPA Selection Guidelines in respect of the numbers of inshore waterbirds outside the breeding season (Stroud et al 2001).
JNCC and Marine Scotland Science (MSS) undertook an offshore seabed survey of East of Gannet and Montrose Fields and Norwegian Boundary Sediment Plain Scottish Nature Conservation Marine Protected Areas (NCMPAs) on the Marine Research Vessel Scotia (survey code 1515S) from 19 October 2015 to 2 November 2015.
This report is designed to be a resource to help site managers make decisions on whether and how to treat Vaccinium myrtillus on their land if infected with one of three Phytophthora species. It takes the form a framework containing lists of relevant issues that should be considered in the decision-making process. Current thinking around these issues and their relevance to Phytophthora management is summarised to contribute towards making the most effective decisions for the circumstances.
Solan Bank Reef SCI is located approximately 50km north of Cape Wrath on the Scottish mainland. The site represents the Annex I reef sub-types ‘bedrock’ and ‘stony’ reef (JNCC 2012).
The aim of this report is to provide Natural England and Natural Resources Wales with the evidence needed to form its advice to Government on possible additional features or updates for the SPA classified in Liverpool Bay/Bae Lerpwl. The report presents the numbers of wintering aggregations of inshore waterbirds and indicates if species exceed their respective population thresholds under the UK SPA Selection Guidelines within the area of search.
This report collates five winter seasons of aerial survey data (2003/04, 2004/05, 2005/06, 2006/07, 2007/08) were analysed using distance sampling methods. The means of the highest counts from each winter (mean of peak) were used to define the size of the population of each species in the Outer Thames Estuary, as is standard practice deriving from the Ramsar convention. The numbers of little gull and great cormorant were assessed against the UK SPA selection guideline thresholds (Stroud et al 2001).
This report presents population estimates for waterbirds in the Greater Wash area of search during the winter period October to March, inclusive, based on aerial survey data collected during the period 2002 to 2008. The numbers of these species are assessed against the population thresholds advised in the UK SPA selection guidelines. Musgrove et al (2013) was used for UK population estimates and biogeographic population estimates were from Wetlands International, WPE5 (2015). Where species populations meet these thresholds in the area of search important aggregations are identified with a view to delineation of a possible SPA boundary.
This report describes the findings of a desk study carried out by British Geological Survey (BGS) for the Joint Nature Conservation Committee (JNCC) covering the Braemar Pockmarks SCI area. The Braemar Pockmarks SCI is located in the UK Northern North Sea in the vicinity of the Braemar field (UKCS Block 16/3). This site was submitted to the European Commission on 31st August 2008, under the EC Habitats Directive: 1180 Submarine structure made by leaking gases, and was approved as a Site of Community Importance (SCI) by the European Commission.
This report is the product of a desk study by the British Geological Survey (BGS) for the Joint Nature Conservation Committee (JNCC). The scope of the desk study included a comparison of the JNCC 2012 multibeam/sidescan dataset from the Scanner and Braemar pockmarks areas in the northern North Sea with similar historic datasets noting morphological change. Also within scope were a record of gas seepage and Methane-Derived Authigenic Carbonate (MDAC) observations and an examination of sedimentation rates and evidence of anthropogenic causes of sedimentation.
