“…Areas with the habitat type 3160 are widespread in Europe but very unequally distributed. The habitat type comprises chiefly bog pool communities which are common within peatlands throughout north‐western Europe where cool temperatures and high precipitation favour the formation of blanket bogs (Rodwell 1991, Gray et al 2022). In contrast, the area of this habitat type in Mediterranean EU countries is very small and in Portugal, Spain and Italy actually restricted to the sections of the Atlantic or Alpine biogeographic regions, respectively.…”

Nutrient-poor waters with small Utricularia species have been unknown in most of southern Europe and the Balkans. All the more notable are occurrences of Utricularia ochroleuca and Utricularia minor in north Greece. The records presented in this paper extend the known southeast European distribution boundaries of both species southward, and constitute U. ochroleuca a new species to Greece and southern Europe. U. ochroleuca was found in small peaty pools and seepage sites with base-poor water within subalpine fens and headwaters, U. minor in very shallow base-containing waters of spring brooks in upper montane ophiolite environments. The plant species composition of the Utricularia vegetation and its habitats are described. The pertinent vegetation types -Utricularietum ochroleucae and Scorpidio-Utricularietum, respectively, as well as their higher-ranking syntaxa -are new to Greece and the Balkans. The vegetation with U. ochroleuca forms part of the Annex I habitat type 3160 of the EU Habitats Directive, which is also new to Greece. Nature conservation status and management conditions of the detected plant communities and habitats with Utricularia in northern Greece are discussed.

“…Ireland's working application of the Interpretation Manual of EU Habitats describes both lake habitat types based on a combination of expected water chemistry conditions, occurrence of typical macrophytes species and geology (O'Connor, 2015). However, the information used to develop this classification was limited to those included in national water and vegetation reports, thus failing to provide a complete and detailed characterisation of the two lake habitats which eventually relied heavily on expert opinion (Gray et al, 2022;O'Connor, 2015). Lake habitat 3110 were identified as nutrient and base poor lakes (low phosphorous, nitrogen and alkalinity) with weakly acidic waters (pH > 5.5) and an isoetid type of vegetation growing on the underlying granite or sandstone bottoms.…”

“…The European Red List of Habitats highlights the presence of Amphipoda, Mysida and Gastropoda as well as Ephemeroptera, Plecoptera and Trichoptera for lake habitat 3110 (EEA, 2016a). In contrast, invertebrates are considered particularly important for dystrophic lake habitat 3160, with these lakes potentially hosting multiple rare species, therefore, invertebrates could support their monitoring especially since this lake habitat has low macrophyte diversity (Cappelli, 2024;EC, 2013;Gray et al, 2022;O'Connor, 2015). Previous knowledge of macroinvertebrate assemblages in dystrophic lakes and ponds reveals them to be dominated by Diptera (Chironomidae), Trichoptera, and predaceous insects such as Coleoptera, Hemiptera and Odonata (Beadle et al, 2015;Desrochers and van Duinen, 2006;EEA, 2016b;Ozoliņš et al, 2021, Pakulnicka andKruk, 2023).…”

“…This is due to several pressures such as agriculture, forestry, and peat erosion, as well as poor land management practices. Incomplete characterisation and limited data are also hindering the implementation of accurate monitoring methods and assessment tools which determine the conservation condition of these lake habitats (Gray et al, 2022;NPWS, 2019;O'Connor, 2015).…”

“Oligotrophic waters containing very few minerals of sandy plains” (habitat code 3110) and “Natural dystrophic lakes and ponds” (habitat code 3160) are two protected lake habitats under Annex I of the European Union Habitats Directive. Despite this level of protection, their conservation condition is considered unfavourable in most European biogeographic regions. The available classifications rely heavily on water chemistry and phytosociology while leaving other biological taxa under described. This study tested the use of Coleoptera and Odonata communities as a monitoring tool to characterise and distinguish both lake habitat types. Samples were collected from 24 sites in western Ireland over two seasons (spring and summer) using standard sweep netting methods. Despite a considerable level of overlap in assemblages found, communities were shaped by lake habitat type, sampling region and season. Overall, lake habitat 3110 hosted a higher diversity of taxa in summer dominated by dragonflies associated with larger, warmer waters, while lake habitat 3160 reflected higher Coleoptera diversity in spring typical of small, turbid, stagnant waterbodies. This research highlights the potential use of aquatic invertebrates as an important monitoring tool for these protected lake habitats. Findings of this work deepen current knowledge about these habitats and fill gaps in their classification, hence improving conservation condition assessment methods for Member States when reporting under the Habitats Directive.
