EXECUTIVE SUMMARY Nine Water Framework Directive fish surveillance monitoring stations were surveyed within the Loughs Agency jurisdiction in 2016. Six were within Northern Ireland and three in Ireland. 22% of sites surveyed were classified as high status, 22% as good status and 33% as moderate status, 22% poor. 0% of sites were classified as bad status.

22 33

High Good Moderate Poor Bad

Classification in 2016 was completed using the WFD compliant classification tool, Fish Classification Scheme 2 Ireland (FCS2 Ireland) with the option of a professional judgement over ride. No results were over ridden using professional judgement in 2016. An overview of the classification system is provided and a synopsis of the survey data presented.

Additional data and information has been presented in a series of excel spreadsheets and ESRI Arc GIS shape files. All data reported is stored within the Loughs Agency Geographical Information System (GIS) and is available upon request. Photographs of each site have been included and outline recommendations made for consideration as part of any programme of measures.

Additional indicative classifications have been derived for water bodies within the Foyle and Carlingford areas where certain criteria have been applied to semi quantitative Salmon Management Plan electrofishing data. These criteria have been developed by the Northern Ireland Water Framework Directive Fish Group and are outlined within this report.

A number of recommendations are made to ensure the continued success of Water Framework Directive river fish monitoring.

INTRODUCTION

This report has been prepared to disseminate results for Water Framework Directive fish monitoring within the Foyle and Carlingford areas as managed by the Loughs Agency. The Loughs Agency reports this information to the Northern Ireland Environment Agency and the Environmental Protection Agency in Ireland. The report provides classifications for water bodies with surveillance monitoring stations and for water bodies covered by routine semi quantitative Salmon Management Plan monitoring within the Loughs Agency jurisdictions of the Foyle and Carlingford areas for 2016. Additional information has been provided in electronic format.

WFD compliant fish surveys at surveillance stations are required under national and European law. Annex V of the WFD outlines that rivers are included within monitoring programmes and that the composition abundance and age structure of fish fauna are examined (Council of the European Communities, 2000).

A synopsis of targeted Water Framework Directive river fish sampling within the Foyle and Carlingford areas has been provided below for fieldwork conducted in 2016.

Other sites outside the Foyle and Carlingford areas have been monitored by the Agri Food and Biosciences Institute (AFBI) under contract to NIEA. Loughs Agency and AFBI have previously collaborated on a number of surveys to ensure continuity of sampling methods, no collaborative surveys were conducted in 2016.

BASIS FOR WATER FRAMEWORK DIRECTIVE FISH CLASSIFICATION

The Fish Classification Scheme 2 tool for Ireland (FCS2 Ireland) has been developed to classify fish fauna from high status to bad status to comply with Water Framework Directive requirements. FCS2 Ireland is a statistical model based on the Environment Agency (England) Fisheries Classification Scheme 2 (FCS2). FCS2 Ireland compares the observed abundance of fish of each species with a site specific prediction of the expected fish community under near undisturbed “reference conditions”. The predicted reference conditions are Page 12 of 98

estimated using models created for each part of the UK and Ireland (UKTAG, 2013).

FCS2 Ireland was used for the first time within the Loughs Agency jurisdiction in 2012 to classify fish in rivers. This methodology is WFD compliant and has replaced professional opinion as the main method of classification. A professional opinion over ride can still be employed if deemed appropriate. Fish classifications will be incorporated into final surface water classifications.

Data collection was conducted in the field during June, July, August and September 2016 and involved the use of a quantitative electrofishing methodologies and a semi quantitative methodology. Electrofishing is the preferred method for WFD surveillance monitoring of fish in rivers to obtain a representative sample of fish from each monitoring station. This method is compliant with the European Committee for Standardisation (CEN) standards for assessing fish stocks in wadeable rivers (CEN, 2003).

Quantitative electrofishing requires the netting off of a section of river using stop nets. Removal sampling is then conducted utilising electrofishing equipment with the numbers, age class and species of each fish being recorded for each pass. After an appropriate depletion has been achieved, which facilitates a density estimation to be made, all fish were returned alive to the river.

Additional habitat variables were recorded and the exact sampling locations were recorded using a Trimble Juno hand held GPS unit.

Professional judgement over ride can be utilised where classifications are deemed to be inaccurate due to the presence of barriers to migration downstream of the sampling stations. Consideration of this issue has not been incorporated into the FCS2 (Ireland) model at this time. Other scenarios for professional judgement over ride include significant deviation from expected classification and higher than normal water levels during survey.

This site is composed predominantly of grade 3 nursery habitat (45%) with grade 3 holding habitat (40%) and grade 3 spawning habitat (15%).

This site was surveyed upstream of the surveillance monitoring station which is located at Clady Bridge. The site surveyed is downstream of Liscooley Bridge and has been moved for operational reasons. It is approximately 7km upstream from Clady Bridge. The exact location is given in the spreadsheets supplied which provide grid references for upstream and downstream locations. With a change to the waterbody boundaries post 2016, the survey location may need to be reviewed.

The site is on the main stem of the River Finn. Additional biological information is available in the spreadsheets provided. The diversity of in-channel and riparian habitats are good.

Proposed Programme of Measures

Within the waterbody, potential programmes of measures could include improved riparian land management in the form of stock proof fencing and native buffer zone creation. Some improvement of in-channel substrate could be conducted by either loosening compacted gravels or by importing new substrate. Treatment of riparian invasive species is also required. At the waterbody level riparian invasive species particularly Himalayan balsam is a significant problem. Bank erosion as a result of trampling by cattle is also an issue within the waterbody. Channel maintenance, dredging and flood banks are also significant issues within the waterbody.

Proposed Programme of Measures

This water body generally has good channel structure. It is a high energy gravel river. Local impacts within this waterbody include the presence of Himalayan balsam. Water crowfoot (Ranunculus penicillatis spp) is present at this site and is one of the primary habitat features for the rivers designation as an Area of Special Scientific Interest (ASSI) and Special Area of Conservation (SAC). There is evidence of some bank protection works which has the potential to disconnect the river from its natural floodplain. The surrounding land use is silage production and grazing with some arable crop rotation. Potential programmes of measure could include riparian fencing set back from the left hand bank and control of invasive species.

This site is composed of grade 3 nursery habitat (65%), grade 3 spawning habitat (20%) and grade 3 holding habitat (15%). This site lies within a major maintained channel. There is some trampling by cattle on the left hand bank with Himalayan Balsam also present. Heavy aquatic weed growth is evident at this site. Due to the poor quality habitat present at this site recruiting fish may pass quickly through this area.

Results

Site F10626 was surveyed using a single pass quantitative electrofishing method.

From this data minimum density estimates have been calculated for all species and age classes present. No salmonids were recorded at this site. Significant impacts were noted including excessive drainage which has left the watercourse devoid of suitable salmonid habitat. Excessive weed and plant growth has choked the watercourse from the bridge upstream. The gradient of the channel Page 49 of 98

COPYRIGHT © LOUGHS AGENCY OF THE FOYLE CARLINGFORD AND IRISH LIGHTS COMMISSION 2017

has been altered to such a degree from drainage that there is little to no flow in lower water conditions.

This site has been left unclassified for channel habitat due to its recent extensive and intensive drainage below bed level. This site was previously of higher value with more natural channel structure throughout.

Impacts at the site included extensive and intensive drainage below bed levels resulting in low flow velocities and extensive in channel vegetation upstream of the dredged area. This manifests itself in a number of ways including featureless river habitat unsuitable for salmonid species and choking of the watercourse which would prevent salmonid migration. The site is also extensively tunnelled throughout.

Proposed Programme of Measures

Potential programmes of measures include the development of catchment initiatives to ensure water quality and habitat quality are maintained or improved. Bush and tree trimming is required to permit some dappled shade.

Page 50 of 98

COPYRIGHT © LOUGHS AGENCY OF THE FOYLE CARLINGFORD AND IRISH LIGHTS COMMISSION 2017

Extensive in channel habitat unit creation is also required to replace the lost salmonid habitat through the excessive drainage works.

This site is composed predominantly of grade 1 holding habitat (30%) with grade 3 spawning habitat (15%) and grade nursery habitat (5%). The remainder of the habitat is unclassified.

Additional biological information is available in the spreadsheets provided.

This water body has previously been improved. There is generally poor salmonid nursery habitat. There is a good riparian buffer zone, good elver habitat and optimal Lamprey habitat. The unclassified habitat forms a rather uniform featureless stretch holding few fish of any species.

This site is composed predominantly of grade 2 nursery habitat (60%) with grade 1 holding habitat (30%) and grade 3 spawning habitat (10%).

Additional biological information is available in the spreadsheets provided.

This water body forms an inflowing tributary to Lough Mourne which is an impounded lough used as a public water supply. A “V” notch weir is located immediately downstream from Lough Mourne which may impede migratory fish species from routinely moving between the Mournebeg River downstream and Lough Mourne. There is also and natural barrier at the upstream limit of the site which would prevent the upstream migration of salmonids.

Potential programmes of measures could include ensuring fish passage provision is appropriate at the outflow of Lough Mourne to the Mournebeg River. Plans to increase the size of Lough Mourne and to increase the size of the impoundment are being developed to secure a public water supply for a growing regional population with increased demands for water.

This site is composed predominantly of grade 3 nursery habitat (70%) with grade 2 holding habitat (15%) and grade 3 spawning habitat (15%).

Additional biological information is available in the spreadsheets provided.

This water body experiences high water temperatures periodically during summer due to poor riparian shading and the present of dark macrophytes on the bed of the river which absorb heat readily. There is no riparian fencing on either bank but there are at present no signs of trampling by livestock. There is a significant quantity of exposed bedrock on the channel bed which limits the productive capacity at this site. There is some tunnelling by trees downstream and there is some potential for establishing riparian trees throughout the water body.

This site is composed predominantly of grade 2 nursery habitat (40%) with grade 2 holding habitat (35%) and grade 3 spawning habitat (25%).

Additional biological information is available in the spreadsheets provided.

The sampling site is located upstream of the main settlement of Moville. The site has good in channel habitat diversity. Rhodendron ponticum is present on both banks and there is historic bank protection works. This waterbody has been modified in the past with the creation of weirs and other associated infrastructure upstream and downstream of this location. Atlantic salmon were recorded at this site in 2016 having previously been absent in the 2010 and 2013 surveys. Water quality, bank erosion, invasive riparian species and barriers to fish migration are all issues within this waterbody.

SEMI QUANTITATIVE/SALMON MANAGEMENT PLAN CLASSIFICATIONS

For classification in 2016 the NI WFD Fish Group continued to adopt the set of rules for deriving indicative fish classifications for waterbodies in which annual semi quantitative/salmon management plan electrofishing surveys are conducted. Within the Foyle and Carlingford areas approximately 500 sites are semi quantitatively surveyed annually. The ability to derive indicative classifications greatly facilitates the ability to highlight pressures within specific waterbodies and can assist with the development of programmes of measures.

The refined rules as of January 2013 are listed below.

1. Only use if there are a minimum of three sites per water body - suggest a minimum of the three largest rivers for which data is available – important to record the stations used.

2. Classify according to the dominant salmonid species within the water body where adequate historical data is available.

3. Classify if ≥ 66% of sites agree 4. Classify as Good or better, moderate or Poor or worse 5. Use the most recent years data Site In Agreement Red Burn N/A Stranagoppoge N/A Bredagh N/A Finn No Owenkillew No Cappagh Yes Cloghfin No Jerretspass N/A Newry N/A

CONCLUSION

From 2012 classification has been predominantly based on the FCS2 (Ireland) model. This has replaced the professional opinion classification method as the dominant classification method. A professional opinion over ride exists to correct classifications based on a paucity of information including the presence of barriers downstream to a monitored site. The professional opinion override was not utilised in 2016.

2016 marked the second year in the second monitoring period/cycle of the Water Framework Directive. In 2016 a number of sites were surveyed using a single pass electrofishing survey. When it was not possible to install stop nets due to excessive flow, depth and or width a single pass survey within a defined area was conducted. This approach was instead of the previously utilised multi method approach.

The FCS2 (Ireland) tool has passed the intercalibration process and has now been fully adopted for use across the island of Ireland. Further refinements may be made to the model in the future to incorporate issues such as full consideration of barriers downstream and acceptance of different types of survey data. During the second cycle of the WFD more emphasis will be placed on reasons for waterbody failures and the development of appropriate programmes of measures to address these. This approach will involve wider utilisation of existing fisheries data sets, additional empirical data collection and expert analysis of this information.

A degree of flexibility will need to be maintained in collecting and analysing fisheries data which can be utilised for WFD classification purposes. Early consultation on any potential developments to the FCS2 (Ireland) model should be encouraged through the relevant technical advisory group.
