Map of all of Northern Ireland's lakes for which data was available to NIEA during 2013.

Lakes defined under Article 2(5) of the Water Framework Directive. Only lakes of >50Ha or those that are part of the intercalibration process are included.

The Water Framework Directive (WFD) required Northern Ireland to define both surface and groundwaters as a coherent set of hydrological units. These units would then be monitored and managed to prevent deterioration in water quality and aquatic ecosystems through the implementation a programme of measures to drive improvements. This map displays Northern Ireland lakes which are greater than 50ha, which are assessed under WFD legislation and have been reported to EU from 2016.

Ecological statuses of all lake waterbodies across Northern Ireland for the 2016-2021 Waterframework Directive cycle. Lake outlines available from OpenDataNI under the UK Open Government Licence. 2021 statuses provided by the DAERA NIEA Water Management Unit on 21/12/2023.

The European Diatom Database (EDDI) is a web-based information system designed to enhance the application of diatom analysis to problems of surface water acidification, eutrophication and climate change.

This dataset includes 54 relatively small, shallow lakes from Northern Ireland. All sites are lowland, alkaline and cover a wide range of phosphorus concentrations. Surface sediment samples were collected during April 1990 and May 1991 and diatoms were counted by John Anderson. A regional diatom-total phosphorus transfer function was developed from these data and details are given in Anderson et al. (1993) and Anderson & Rippey (1994). These sites also form part of a larger training set used to develop a NW European diatom-total phosphorus inference model (Bennion et al., 1996). Palaeolimnological studies have been undertaken at a number of these sites (e.g. Anderson, 1989, 1997; Anderson & Rippey, 1994; Anderson et al., 1993; Rippey et al., 1997).

This table provides the raw data from river monitoring sites including Water Framework Directive monitoring sites. It should be noted that, as the data set is in its raw state, it cannot be used to provide a status without processing. The data set does not show Limits of Detection or Limit of Quantitation which would require a value to be treated as a half value for WFD calculation. In addition both altitude and alkalinity affect status calculations for some parameters. The data set may contain results which are erroneous due to typos, sampling error or contamination, such data points are usually several orders or magnitude above expected values.This is the first in a series of water data sets being made available as Open Data.

The European Diatom Database (EDDI) is a web-based information system designed to enhance the application of diatom analysis to problems of surface water acidification, eutrophication and climate change.

The Northwest European dataset is an amalgamation of six smaller regional datasets from southeast England, the English Midlands, Wales, Northern Ireland, Denmark, and Sweden. The lakes are mostly lowland, shallow, small, slightly acid to alkaline waters with agricultural activity and/or forestry in the catchments. The combined dataset spans a long TP gradient from oligotrophic to hypertrophic waters. Surface sediment samples (0-1 cm) were collected from the deepest point of each lake over the period 1990-1993 and diatoms were counted by either Helen Bennion (southeast England, meres, Wales), John Anderson (Northern Ireland, Denmark, Sweden) or Tim Allott (Wales). A program of taxonomic harmonisation was undertaken to construct a unified database of diatom data. The full dataset consists of 164 lakes but this was reduced to a training set of 152 lakes following data screening. This training set was used to develop a WAPLS diatom-TP transfer function and component 2 gave the lowest prediction error (RMSEP=0.21 log10TP �g l-1, apparent r2=0.91). Further details of the training set and transfer function are given in Bennion et al., 1996) and the model has subsequently been applied to numerous diatom sequences to reconstruct lake nutrient histories (e.g. Bennion et al., 1996, 1999, 2000, 2001).

The Eel Monitoring Programme (EMP) at Inland Fisheries Ireland uses fyke net surveys to assess yellow eel populations in lakes, main channel rivers, canals, transitional waters and lagoons. For further information on the methodology used in the surveys please contact IFI, methodology includes the use of chains of 5 nets, along with repeating historical surveys with chains of 10 nets. This dataset contains data including year of sampling, waterbody name and type, catchment name and river basin district (RBD). The Erne catchment is monitored as part of the North West International River Basin District (NWIRBD) as an eel management unit under Irelands Eel Management Plan in collaboration with agencies in Northern Ireland.Catch data on yellow eels for surveys are presented, including, numbers of eels captured/measured and summarised length and weight results for summer fyke netting European Eel surveys (yellow eel life stage) along with length frequency breakdowns of catches. Net*Nights are calculated by multiplying the number of nets set by the number of night that the nets were allowed to fish.

CSNIreOT1 begins in 1992 and ends in 2016, Moriarty et al (2017) detail the survey's history. The Celtic Sea Northern Irish Quarter 1 Otter Trawl Groundfish Survey Monitoring and Assessment Data resource contains both biological and sampling information. There are two sampling areas a "Full" data set, this includes rectangles that have a poor temporal sampling record. The "SSA" or "Standard Survey Area" sampling area only contains rectangles that have consistent temporal sampling and meet the criteria set out in Moriarty et al, (2017). The "sampling information" contains all the technical information required to describe each individual haul. The "biological information" contains all of the biological information required to describe the species length and weight distributions in each haul. Biological information is further classified by "baseline" data. This data contains a mix of species, genus, and family classifications, with a tag to say if it required further assessment and "null" length values, with a tag to say a length frequency distribution needs to be assigned. The "k-NN" or "k" number of nearest neighbours data has reconciled all of the taxonomic data to the highest resolution possible, and assigned an appropriate length distribution to the sample in question. Product type: * This product is the Standard Survey Area - Standard Monitoring Programme this is the recommended product for all analyses. * This product is the knn/resolved product which is recommended for all analyses.

The Water Environment (Water Framework Directive) Regulations (Northern Ireland) 2017. The Water (Amendment) (Northern Ireland) (EU Exit) Regulations 2019 ensures that the Water Framework Directive (WFD) (as transposed) and the various supporting pieces of water legislation are implemented in Northern Ireland. The legislation defines 6 year cycles of monitoring and action to improve or maintain environmental water quality standards.Water bodies are the basic management units for monitoring, reporting and assessing compliance with the Water Environment Regulations' environmental objectives. For the 2nd cycle (2016-2021) 571 water bodies were identified in Northern Ireland, of these 496 are surface water bodies: including 450 rivers, 21 lakes, and 25 transitional and coastal waters (Marine); the remaining 75 are groundwater bodies.This layer displays the river waterbody boundaries based on surface water flow hydrological units. This is a 2016 2nd cycle revision of the earlier 2009 1st cycle hydrological unit split. Future revisions are not planned.

The Biologically Sensitive Area sets out the criteria and procedures for a system relating to the management of fishing effort in waters around Ireland that are considered biologically sensitive. A specific effort regime shall apply to the area enclosed by the coast of Ireland to the south of 53° 30' N and to the west of 07° 00' W and straight lines sequentially joining the following geographical coordinates: - a point on the coast of Ireland at latitude 53° 30; N, latitude 53° 30 N, longitude 12° 00 W, latitude 53° 00 N, longitude 12° 00 W, latitude 51° 00 N, longitude 11° 00 W, latitude 49° 30 N, longitude 11° 00 W and latitude 49° 30 N, longitude 07° 00 W. A point on the coast of Ireland at longitude 07° 00 W. An area to the South and West of Ireland has been identified as an area of high concentration of juvenile hake. This area has been made subject to special restrictions on the use of demersal gear. For the same conservation purpose it should also be subject to specific effort limitation requirements within the general system described above. A review of these requirements by December 2008 would allow the Council to reassess the situation. Council Regulation (EC) No 1954/2003 of 4 November 2003 on the management of the fishing effort relating to certain Community fishing areas and resources and modifying Regulation (EC) No 2847/93 and repealing Regulations (EC) No 685/95 and (EC) No 2027/95. The area covered by this designation includes the south coast of Ireland in the Celtic Sea from Waterford to Mizen Head and the south-west coast of Ireland in the North Atlantic Ocean from Mizen Head to Galway Bay. In 2003 the EU Commission established a Biologically Sensitive Area (BSA); off the south west of Ireland. Area designated via fisheries science research information. Area has been designated as a protected site for fishing effort monitoring. The Biologically Sensitive Area has been created by the European Council directive. Area 100% designated a protected site for biological sensitivity. .hidden { display: none }

Information on forest pest outbreaks, their management and surveillance activity for both Northern Ireland and the Republic of Ireland are documented in a series of forestry annual governmental reports (written by the Northern Ireland Forestry Service, Coillte, The Department of Agriculture, Food and the Marine and the Republic of Ireland Forestry and Wildlife Service). We collated 102 of these annual reports covering the period 1970 - 2020 (51 reports for each of Northern Ireland and the Republic of Ireland). The information on forestry pests available in these reports was digitised via a data extraction protocol and a dataset of the results of this are recorded in the ODonnell_et_al_2024.csv file.

The readme file README_ODonnell_et_al_2024.txt is intended to explain the ODonnell_et_al_2024.csv file, and all of the information contained within.
