Landmark High Court Victory Protects Ceibwr Bay and Its Wildlife

By Renee Karunungan

 

On 5 September 2025, the High Court delivered a landmark judgment: planning permission for the proposed Moylgrove Adventure Hub—a development comprising coasteering, kayaking, and other outdoor activities near Ceibwr Bay—has been quashed. Justice Eyre ruled that Pembrokeshire Coast National Park Authority’s decision in October 2024 was unlawful, citing serious failures in safeguarding protected species and habitats.

Ceibwr Bay is one of Pembrokeshire’s most environmentally sensitive sites. It falls within the Cardigan Bay, Pembrokeshire Marine, and West Wales Marine Special Areas of Conservation (SACs), and forms part of the Aberarth–Carreg Wylan Site of Special Scientific Interest (SSSI). The area hosts pupping grey seals, seabirds like razorbills, guillemots, fulmars, choughs, kestrels, and even otters—none of whose habitats could be compromised by increased recreational disturbance.

Wild Justice, supported by local residents, launched this judicial review after raising concerns that the planning authority had not provided adequate environmental information and that mitigation measures—such as an Access Management Plan—were insufficient or inadequately assessed. Justice Eyre accepted that the planning permission was improperly granted, demanding a fresh application backed by robust assessment if development is to proceed.

 

 ELF’s Role

This judicial win follows ELF’s earlier involvement in the pre-litigation stage; ELF was particularly delighted when this case was picked up by WJ. 

As early as July 2024, ELF received community concerns about growing disturbances to nesting seabirds and protected wildlife at Ceibwr Bay through the increase in marine recreation over the past 10 years. We flagged immediately the lack of meaningful restrictions in the nature reserve, the urgent requirement for a Habitats Regulations Assessment (HRA) to support the planning application for the proposed marine recreational hub and supporting local residents in objecting to the proposal. 

Why This Matters

• Reinforces Habitat Law Protections: The High Court’s ruling underscores that SACs and recreational SSSIs cannot be treated like ordinary countryside—legal processes must be rigorous, and environmental safety must be the priority. 
• Precedent for National Planning: This decision strengthens the case for stricter habitat assessments in adventure tourism and coastal development across the UK. 
• Validation for Community Campaigns: It demonstrates how local voices, supported by expert legal advocacy, can successfully hold planning authorities to account.

 

What’s Next?

Pembrokeshire Coast National Park Authority may choose to appeal, but if not, the developer must submit a new planning application—one that must meet stringent environmental standards.

For communities and regulators alike, this moment highlights that biodiversity protection must come first, especially when it features critically designated sites.
