European UnionI want to challenge a development that will destroy local wildlife habitat. Does EU law help?
Yes, EU law provides strong protections for wildlife habitats through the Habitats Directive and Birds Directive, which require Member States to protect designated sites and assess development impacts.
What the Law Says
EU law establishes binding obligations for Member States to protect wildlife habitats, especially through two cornerstone directives: the Habitats Directive and the Birds Directive. These laws create the Natura 2000 network and require rigorous environmental assessments before approving potentially harmful developments.
The Habitats Directive (Council Directive 92/43/EEC) requires EU countries to maintain or restore natural habitats and wild species at a 'favourable conservation status'. It mandates the designation of Special Areas of Conservation (SACs) and strict protection for species listed in its Annexes.
The Birds Directive (Directive 2009/147/EC) protects all naturally occurring wild bird species in the EU and their habitats — including breeding, feeding, and resting sites — and requires designation of Special Protection Areas (SPAs). Together, SACs and SPAs form the Natura 2000 network.
Under the Environmental Impact Assessment (EIA) Directive (2011/92/EU, as amended), projects likely to have significant effects on protected sites must undergo mandatory assessment — including alternatives, mitigation, and public consultation. Article 6(3) of the Habitats Directive is especially critical: it prohibits authorisation of plans or projects that would adversely affect the integrity of a Natura 2000 site unless there are no alternative solutions and imperative reasons of overriding public interest.
Statutory TextAny plan or project not directly connected with or necessary to the management of the site but likely to have a significant effect thereon, either individually or in combination with other plans or projects, shall be subject to appropriate assessment of its implications for the site in view of the site’s conservation objectives.
— Habitats Directive 92/43/EEC, Art. 6(3)
Statutory TextMember States shall take the requisite measures to maintain the population of all species of naturally occurring birds in the wild state at a level which corresponds in particular to ecological, scientific and cultural requirements, while taking account of economic and recreational requirements.
— Birds Directive 2009/147/EC, Art. 2
Statutory TextProjects listed in Annex I shall be made subject to an assessment with regard to their effects on the environment prior to consent.
— EIA Directive 2011/92/EU, Art. 3(1)
What Courts Have Said
The Court of Justice of the European Union (CJEU) has repeatedly reinforced the strict interpretation of Article 6(3) of the Habitats Directive, making it a powerful tool for challenging damaging developments.
Ireland failed to assess the impact of a road project on a Natura 2000 site; the Court held that even indirect effects must be evaluated and that failure to carry out an appropriate assessment breaches EU law.
The Court ruled that 'appropriate assessment' must be based on 'complete, precise and definitive findings and conclusions capable of removing all reasonable scientific doubt' about the project’s impact on site integrity.
What to Do
Check if the development site overlaps with a Natura 2000 site (search via the European Environment Agency’s Natura 2000 viewer)
Request the full Appropriate Assessment report from the national authority — it must be publicly available and scientifically robust
File a formal objection during the public consultation period (minimum 30 days under EIA Directive)
If approval proceeds without proper assessment, lodge a complaint with the European Commission via the Infringement Complaint Portal
Consider legal action in national courts — cite CJEU rulings like Waddenzee and Commission v Ireland to challenge procedural flaws
