4.3.2 EUNIS habitat classification The European Nature Information System (EUNIS) habitat classification51 is also a pan-European system, which was developed between 1996 and 2001 by the European Environment Agency (EEA) (EUNIS 2002). The starting point was the Palaearctic Habitat classification, extended from the CORINE habitat classification which was developed for use by the European Community in the pilot CORINE biotopes programme by the EU Commission 1986–1991 (Davies & Moss, 2002). A novel feature of that hierarchical classification was the development of criteria in order to make a key for identification of habitats, analogous to keys for identification of species. Mires are included in unit D – ‘Mire, bog and fen habitats’. The following subunits correspond rather well to the Estonian mire habitat types: D1.1 Raised bogs D1.1/P-51.1 Active, relatively undamaged raised bogs D1.12 Damaged, inactive bogs D2.2 Poor fens D2.2/P-54.42 [Carex nigra], [Carex canescens], [Carex echinata] fens D2.3 Transition mires and quaking bogs D2.3/P-54.51 [Carex lasiocarpa] swards D2.3/P-54.52 [Carex diandra] quaking mires D2.3/P-54.53 [Carex rostrata] quaking mires D2.3/P-54.54 [Carex limosa] swards D2.3/P-54.55 [Carex chordorrhiza] swards D2.3/P-54.57 [Rhynchospora alba] quaking bogs D2.3/P-54.58 [Sphagnum] and [Eriophorum] rafts D2.3/P-54.59 [Menyanthes trifoliata] and [Potentilla palustris] rafts D2.3/P-54.5C [Eriophorum vaginatum] quaking bogs D4 Base-rich fens D4.1/P-54.22 [Schoenus ferrugineus] fens D4.1/P-54.23 Subcontinental [Carex davalliana] fens D4.1/P-54.21 Tall herb fens D4.1/P-54.2K [Sesleria caerulea] fens D4.1/P-44.93(p) [Myrica gale] scrub on rich fens D4.1/P-54.12 Hard water spring mires D5 Sedge and reedbeds, normally without free-standing water D5.1/P-53.112 [Phragmites australis] beds normally without free-standing water D5.1/P-53.12(p) [Scirpus lacustris] beds normally without free-standing water D5.1/P-53.13(p) [Typha] beds normally without free-standing water
