The Department of Agriculture, Environment and Rural Affairs' (DAERA's) management of Northern Ireland’s protected sites for nature is being investigated.

The Office for Environmental Protection (OEP) launched the probe to determine DAERA’s compliance with its obligations.

The OEP will pay close attention to pressures imposed on these protected sites, particularly nutrient pollution, and whether they are being addressed by DAERA through adequately designed support.

Previous investigations

A previous investigation was carried out by OEP into DAERA's implementation of laws in these areas.

The findings were published in April 2025 where it called for urgent action to be taken in the protection and restoration of the sites.

DAERA's response towards the report was described as "positive".

However, questions are now being raised on whether actions to address the highlighted issues are being implemented.

The OEP will also ensure that DAERA is complying with its obligations to designate, manage and monitor protected sites, as well as adapting protected sites so that they will be able to achieve conservation objectives.

The investigation

The OEP will be looking into the management of Special Areas of Conservation (SACs), which are protected by the EU.

In Northern Ireland, this includes areas such as Lough Melvin; the Cuilcagh mountains; and the Magheraveely Marl Loughs.

It will also be investigating Areas of Special Scientific Interest (ASSIs), including sites such as Lough Neagh; the Antrim Hills; and Belfast Lough.

Should the investigation be found non-compliant with environmental law the OEP will ensure that effective measure are put in place to ensure effective management for SACs.

Further steps are being taken to further the conservation in ASSIs and reduce pressures, with plans in place for further designations of both categories of site, according to the OEP.

Chief regulatory officer for the OEP, Helen Venn said: “Protected sites for nature include places of historic and cultural significance, and they are also one of the most important tools for restoring nature.

“Our investigation will look into whether this is due to serious failures to comply with the environmental laws in place to ensure that such sites achieve good condition.”  

DAERA

In response to the announcement of the investigation, Minister for Agriculture, Environment and Rural Affairs Andrew Muir said:

"Our protected sites are vital in supporting both nature recovery and climate resilience and recognise the need for robust protections.

"I share the priority that the Office for Environmental Protection places on them.

“I and my officials will co-operate fully with the OEP as it undertakes a formal investigation into DAERA’s implementation of protected sites law.”
