The Habitats Directive (more formally known as Council Directive 92/43/EEC on the Conservation of natural habitats and of wild fauna and flora) is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised.

The Habitats Directive required national governments to specify areas that are expected to be ensuring the conservation of flora and fauna species. This led to the setting up of a network of protected areas across the EU, along with 'Special Areas of Conservation', which together with the existing Special Protection Areas, became the so-called Natura 2000 network established to protect species and habitats.

This directive is one of the main pillars of the European Union's system of wildlife and nature conservation, another being the Birds Directive. The Habitats Directive, together with the Birds Directive, are also called the "nature directives".

The Habitats Directive consists of 24 articles of legislation to which all member states must comply. Article 17 of the directive sets the terms and standards for reporting on both the habitats and species listed in the annexes by the individual EU member countries. It stipulates a report from each member country on the state of nature every six years. The first preliminary reports were due in 2001 (but only published in 2004), the first actual assessments were due in 2007 (published 2009), the second in 2013 (published 2015), and the third set of assessment reports were due in 2019 (published 2020). The assessments of conservation status differ markedly from those of the IUCN Red List. The aim in the case of the EU conservation status is to assess the distance from a defined favourable situation, as opposed to the distance from extinction. There are three classes of conservation status: favourable (FV), unfavourable-inadequate (U1) and unfavourable-bad (U2).

The annexes of the directive outline the protected habitats and species: Annex I covers habitats, Annex II species requiring designation of Special Areas of Conservation, Annex IV species in need of strict protection, and Annex V species in which member countries may decide for themselves how to manage the population.

History

From 1988 to 1992, the policy was given importance at the national level by policy experts, scientists and ecologists; later on in the 1990s this spawned further political, social and administrative discussions among the relevant countries.

Due to differences in nature conservation traditions, national problems have arisen in the implementation of the directive. Since member states in the south and east of Europe participated less in nature policies, these states experienced problems with the EU provisions. In Germany, Austria, Italy and Belgium, the observation of conflicts between various government layers have caused prolonged delays in the management of nature policies. On the other hand, in member states such as the United Kingdom and Sweden, positive outcomes have developed due to stakeholder involvement, pro-active authorities, agencies responsible for implementation and public participation.

According to one 2014 report there are increasing incompatibilities with the Natura 2000 policy on economic development.Suvi Borgström, Frederik H.

Annex I Annex I lists the specific habitats which have been designated as the a Special Area of Conservation, to which a common EU-wide legislation applies. Certain habitats among those are furthermore designated as "priority habitat types". Habitats in the EU are given codes. An area or habitat can combine two habitats, and be designated as for example code 35.2 × 64.1 - Open grassland with Corynephorus and Agrostis (35.2), in combination with continental dunes (64.1). Example Annex I habitats are:

Open sea and tidal areas Sea cliffs and shingle or stony beaches Atlantic and continental salt marshes and salt meadows Mediterranean and thermo-Atlantic salt marshes and salt meadows Salt and gypsum continental steppes Dunes Sea dunes of the Mediterranean coast Continental dunes, old and decalcified Standing and running freshwater Sections of water courses with natural or semi-natural dynamics (minor, average and major beds) where the water quality shows no significant deterioration Matorral Mediterranean arborescent matorral Thermo-Mediterranean and pre-steppe brush Phrygana Grasslands Natural grasslands Semi-natural dry grasslands and scrubland facies Sclerophyllous grazed forests (dehesas) Semi-natural tall-herb humid meadows Mesophile grasslands Bogs, mires and fens Sphagnum acid bogs Calcareous fens Rocky areas and caves Scree, chasmophytic vegetation on rocky slopes Other rocky habitats Forests - Only (sub-)natural Forests of temperate Europe Mediterranean deciduous forests Mediterranean sclerophyllous forests Alpine and subalpine coniferous forests Mediterranean mountainous coniferous forests The full list of habitats is distributed over 9 main categories.
