2.7. Macrohabitat Glossary
This glossary includes repeatedly reference to numbered CORINE “habitat” categories. For
explanation, see the entry under “corine”.
(gen.): abbreviation for in general; referring to a general category also treated as two or more subcategories
in this database
aapa mire, wetlands: boreal string-mire complexes, with attenuated ridges alternating with linear
pools, or flarks, the outer (marginal) ridges usually dominated by Pinus sylvestris, Alnus, Betula,
Calluna and Empetrum, the flarks by Eriophorum, Menyanthes, Utricularia, Rhynchospora etc. The
central parts of the complexes are characterised by minerotrophic fen vegetation, in which poor
Sphagnum fens are most common, but brown moss fens can be frequent in some regions. The category
includes the sloping fens typical of eastern Finland and parts of Lappland. Habitats Directive, Natura
2000 code: 7310.
Abies (gen.), coniferous forests: forests dominated by firs (Abies spp.) with stands of overmature,
mature and young (saplings/scrub) trees.
CORINE 42.1: FIR FOREST; conifer forests dominated by firs (Abies spp.)
Abies/Larix/Picea, conifer plantations: plantations of fir, larch or spruce: CORINE 83.3111:
EUROPEAN FIR, SPRUCE, LARCH PLANTATIONS
acid fen, fen: CORINE 54.4: ACIDIC FENS; Caricetalia fuscae, Caricion fuscae. Topogenous or
soligenous valley, basin or spring mire systems fed by waters poor in bases. As in the rich fens, the
water level is at or near the surface of the substratum and peat formation is infra-aquatic. The mire
communities themselves, dominated by small sedges and brown mosses or Sphagnum, belong to the
Caricetalia fuscae, but, in large fen systems, they are accompanied by acidocline wet grasslands
(Molinietalia caeruleae), large sedge beds (Magnocaricion) and reed or related communities
(Phragmition). Sphagnum hummocks (51.11) from locally and transition mires (54.5) or aquatic (22.3),
amphibian (22.2) and spring (54.1) communities colonise small depressions. Thus, codes from all the
above categories may need to be used in conjunction to completely describe the fen. The general
category in any case includes, as understood here, beside strict mire communities, their transitions to
humid grasslands; and groupings phytosociologically affiliated with Molinia associations, but rich in
species of the Caricion fuscae, provided they are integrated in a fen system. Acidic fen communities
also occur on small surfaces or within mosaics in other ecosystems, in particular in typical humid
grasslands (37), humid woodlands and thickets (44), decalcified dune slacks (16.3) and spring systems
(54.1). Their presence can be indicated by codes from this unit used in conjunction with the relevant
main codes. Characteristic species of acidic mire communities are Carex canescens, C. echinata, C.
nigra, Eriophorum angustifolium, E. scheuchzeri, Scirpus cespitosus, Juncus filiformis, Agrostis
canina, Viola palustris, Cardamine pratensis, Ranunculus flammula and the mosses Calliergeon
sarmentosum, C. stramineum, C. cuspidatum, Drepanocladus exannulatus, D. fluitans, Sphagnum
recurvum, S. auritum, S. cuspidatum, S. subsecundum, S. apiculatum, S. papillosum, S. russowii.
acidophilous, alpine unimproved grassland: acidophilous unimproved alpine/subalpine grassland,
developed over crystalline rocks and other lime-deficient substrates: CORINE 36.31, 36.32, 36.34.
CORINE 36.31: MAT-GRASS SWARDS AND RELATED COMMUNITIES; closed grasslands of
deep, acid soils of the Alps, Pyrenees, northern Apennines, Jura and higher Hercynian ranges,
developed mostly and abundantly in the subalpine level, dominated or co-dominated by Nardus
stricta, Festuca eskia, F.nigrescens, F.rubra, Alopecurus gerardii, Bellardiochloa (Poa) violacea,
Carex sempervirens, Anthoxanthemum odoratum.
CORINE 36.32: ORO-CALEDONIAN GRASSLANDS; boreo-alpine formations of the higher
summits of Scotland, Cumbria, northern England and northern Wales with Juncus trifidus,Carex
bigelowii, mosses and lichens.
CORINE 36.34: CROOKED-SEDGE SWARDS AND RELATED COMMUNITIES;
Caricion curvulae,Festucion sapinae. Mostly closed Carex curvula, Festuca spp., Oreochloa spp. or
Juncus trifidus grasslands on siliceous soils of the alpine level of the Alps and the Pyrenees, with very
local outposts in the great Hercynian ranges and the Cantabrian Range. Androsace obtusifolia,
A.carnea ssp.laggeri, Campanula barbata, Juncus jacquinii, J.trifidus, Silene exscapa, Gentiana
alpina, Achillea erba-rotta, Euphrasia minima, Luzula lutea, L.spicata, L.hispanica, Lychnis alpina,
