The only fungus in the Habitats Directive is filed under plants

A nature law with no fungi in it

Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora was published in Official Journal L 206 of 22 July 1992, at page 7. Its annexes are what Natura 2000 and the EU species-protection regime rest on. Run a case-insensitive search across the text as consolidated to 14 July 2025 and the string “fung” returns zero hits, as does “myco”. The Polish language version of the same consolidation returns zero for “grzyb” and zero for “mikoryza”.

One fungal organism is listed regardless. In Annex V, under the sub-heading “(b) PLANTS”, between the red algae of the CORALLINACEAE and the mosses of the BRYOPHYTA, three lines read LICHENES, CLADONIACEAE and “Cladonia L. subgenus Cladina (Nyl.) Vain.”. Those are the reindeer lichens: the grey, finely and repeatedly branched cushions that carpet dry pine woodland and tundra. The genus name is written exactly once in the whole directive, on that single line — the only other string match is the syllable buried inside the family name CLADONIACEAE.

Why a lichen belongs in this sentence

The headline rests on a point better stated than assumed. A lichen is not a plant and not a kingdom of its own; it is a fungus living in symbiosis with an alga or a cyanobacterium, and the scientific name of a lichen is the name of its fungal partner. “Cladonia L.” therefore names an ascomycete of the order Lecanorales. It is not, however, a fungus in the everyday sense: a reindeer lichen has no cap and no stipe, and what a walker sees underfoot is a thallus woven from hyphae wrapped around algal cells.

The rank of Cladina itself remains unsettled. Some lichenologists treat the reindeer lichens as a genus in their own right, Cladina Nyl.; others, as the directive does, as a subgenus within Cladonia. Nothing here needs that argument resolved, because the annex lists an entire taxon rather than a species. Cladonia rangiferina, the best known reindeer lichen, is one of its members, but it is nowhere named in the statute.

What an Annex V listing actually does

Annex V is headed “ANIMAL AND PLANT SPECIES OF COMMUNITY INTEREST WHOSE TAKING IN THE WILD AND EXPLOITATION MAY BE SUBJECT TO MANAGEMENT MEASURES”. That is neither strict protection, which lives in Annex IV, nor a trigger for designating a site, which follows from Annexes I and II. The operative provision is Article 14(1), and it is conditional: Member States act only “If, in the light of the surveillance provided for in Article 11, Member States deem it necessary”. Article 14(2) then sets out the available tools — temporary or local prohibitions on taking specimens, rules on collecting periods and methods, licences or quotas, and regulation of sale and transport.

The annexes that bite hardest say nothing about fungi at all. The plant list of Annex II, covering species whose conservation requires the designation of Special Areas of Conservation, opens at PTERIDOPHYTA and runs on through gymnosperms, angiosperms and mosses. Annex IV, which covers species in need of strict protection, states in its own plant section that it contains every plant listed in Annex II(b) plus those named below — and what follows is ferns and flowering plants. Neither list holds a lichen or a fungus. The group headings LICHENES and ALGAE occur nowhere in the act except inside Annex V.

Where the finding stops

The easy misreading is that the EU protects reindeer lichen. It does not. Annex V lets a Member State bring the taking and exploitation of the taxon under management, and then only if its own surveillance shows cause. That is a different instrument from a prohibition, and nothing follows from it for anyone walking through a pine wood.

The mirror error is just as tempting: concluding that lichens play no part in Natura 2000. They do. Annex I, the list of habitat types whose conservation requires designating Special Areas of Conservation, includes 91T0, “Central European lichen Scots pine forests”. A habitat defined by its lichens genuinely produces protected sites — although what is then designated is a forest type, and no lichen is named in it. The precise claim is therefore narrower than it first sounds: no lichen and no fungus is listed as a species in Annex II or Annex IV, and exactly one such listing exists in Annex V.

Nor have the annexes lain untouched since 1992. They were reopened by Directive (EU) 2025/1237 of 17 June 2025, published on 24 June 2025 and in force from 14 July 2025. A long procedural road led there: the Standing Committee of the Bern Convention agreed on 6 December 2024 to move the wolf from Appendix II to Appendix III of that convention, the change took effect under the convention on 7 March 2025, and the directive then brought the Union’s own lists into line. It deleted Canis lupus from Annex IV(a) and replaced its Annex V(a) entry, with Member States required to transpose the change by 15 January 2027. The whole amendment fits in a single substantive article and concerns a single species: it was not a review of the annexes’ taxonomy, and no fungal or lichen taxon was added on the occasion. So the story is not an unread relic of 1992. European legislators opened these very lists fifteen months ago and left the fungi exactly where they were.

Finally, this is not “the only fungus in EU nature law”. The verified claim concerns the annexes of Directive 92/43/EEC and nothing wider. Fungi do appear elsewhere — in Regulation (EU) 2024/1991 on nature restoration, where they form part of the definition of an ecosystem, and in Directive (EU) 2025/2360 of 12 November 2025, the soil monitoring law, which counts fungi among soil micro-organisms and mentions mycorrhizal fungi. National statutes are a separate matter again: Poland protects fungi and lichens under its own instruments, quite independently of this directive.

Checking the annex yourself

The whole exercise takes a few minutes and needs nothing but a browser. The European Commission topic page leads to the text EUR-Lex carries in every official language of the Union; open the consolidated version and search it for “fung”, which returns nothing at all, then for “Cladonia”, which lands on one line of Annex V. One caveat travels with that page, printed at the top of every consolidation: the text “is meant purely as a documentation tool and has no legal effect”, and the authentic version is the one carried in the Official Journal.

The field equivalent is a dry sandy pine wood, where reindeer lichens form a pale mat, brittle enough in drought to break under a boot and soft again after rain. It is worth looking at that mat as the fungus it is — and worth accepting that neither a photograph nor a quick glance will reliably separate Cladonia rangiferina from its close relatives. That, as it happens, is the same caution the legislator showed, by listing an entire subgenus instead of committing to a single species name.
