Freshwater macroinvertebrates are used as an indicator of water quality and Lake flow requirements due to the relative immobility and abundance. This dataset is made up of the species abundance values from the freshwater lake macroinvertebrates surveys conducted across Wales by Natural Resources Wales and former Environment Agency Wales. These surveys are conducted as part of on-going monitoring of river water quality for legislative requirements and to meet business drivers.

A Shoreline Management Plan (SMP) is a large-scale assessment of the risks associated with coastal processes and helps reduce these risks to people and the developed, historic and natural environments. Coastal processes include tidal patterns, wave height, wave direction and the movement of beach and seabed materials. The SMPs set the strategic policy direction for coastal management and identify the most sustainable approaches to managing the risks to the coast in the short term (Epoch 1 0-20 years), medium term (Epoch 2 20-50 years) and long term (Epoch 3 50-100 years). A set of preferred policies are identified which are assigned to 'policy units' for each SMP epoch. A 'policy unit' (PU) is a length of shoreline where a separate shoreline management policy applies. PU's are defined by coastal areas that have similar characteristics in terms of coastal processes and assets at risk, that can be managed efficiently. Four policy options are available for SMPs: - Hold the Line (HTL): an aspiration to build or maintain artificial defences so that the current position of the shoreline remains. This can involve maintaining or changing the standard of protection. - Advance the Line (ATL): by building new defences on the seaward side of the original defences. This is rarely used and is limited to policy units where there is significant land reclamation is considered. There are no policy units in Wales assigned ATL. - Managed Realignment (MR): by allowing the shoreline to move backwards or forwards naturally but managing the process to direct it in certain areas. - No Active Intervention (NAI): where there is no planned investment in coastal defences or operations, regardless of whether or not an artificial defence has existed previously. The coastal management approach for a certain section of coast may change from the status quo where a policy may no longer be practical or acceptable over 100 years. Therefore, a combination of policies may be proposed over the length of the SMP. The dataset identifies which of the second-generation Shoreline Management Plans are applicable to a particular stretch of the Welsh coastline and the policies assigned to policy units related to that particular area. This dataset is a polyline, spatial data layer for the Welsh coast only.Download the data through this link: https://datamap.gov.wales/layers/geonode:nrw_shoreline_management_plan_policies

This data collates all the Phytoplankton samples collected within Wales from 2007 onwards by Natural Resources Wales and former Environment Agency Wales that are held within NRWs KiEco Database. This methodology is based on the principle that additional nutrients (especially nitrogen) can alter the amount of phytoplankton in transitional and coastal waters. Persistent and high counts of phytoplankton taxa are also seen as a measure of disturbance in the phytoplankton community. These surveys are conducted as part of on-going monitoring for legislative requirements and to meet organisational drivers. In addition, sites may be sampled for investigative work, or on an ad hoc basis.

This data collates all the benthic invertebrate samples collected within Wales from 1988 onwards by Natural Resources Wales and former Environment Agency Wales under the Water Framework Directive (WFD) and Clean Seas Environment Monitoring Program (CSEMP) sampling programs. The dataset contains the presence, and abundance, of benthic invertebrate species at specific marine monitoring points held within the KiECO database.

For many of our marine survey techniques we record an NGR at the site because this acts as a central/representative location around which we collect lots of samples. An NGR is then also recorded against each of the samples to give a more accurate sampling location.

This is a beta version of the first open planning data map for London. It contains 16 data sets grouped under the headings of 'Good Growth' and 'Constraints'. You are encouraged to explore the map and give us your ideas about how it can be improved. We are also keen to receive suggestions for what information to add next. Please send your feedback to planningdata@london.gov.uk For more information about planning, please see www.london.gov.uk/what-we-do/planning
