BRYOPHYTESThese criteria are directly derived from the JNCC guidelines for selection of biological SSSIsfor lower plants (available at http://www.jncc.gov.uk/page-2303 accessed 14 October 2010).Some deviations from the JNCC criteria have been made to update information on speciesstatus and to simplify scoring of species for the purposes of this document.To qualify as a prospective County Wildlife Site on grounds of bryophyte interest alone, asite must have post-1949 records for species (or infraspecific taxa) adding up to a totalscore of 100. This is lower than the threshold used for SSSI selection for lower plants(bryophytes plus lichens), which was set at 300.Species should be scored using the list on the following pages, which is arrangedalphabetically. Note recent name changes are accounted for by cross-referencing.Cornwall BAP Priority speciesA site is eligible for selection if it supports a significant population of any of the followingspecies (BAP Priority species automatically score 200):Cephaloziella calyculata Entire ThreadwortCephaloziella dentata Toothed ThreadwortCephaloziella integerrima Lobed ThreadwortCephaloziella nicholsonii Greater CopperwortCryphaea lamyana Multi-fruited River MossCyclodictyon laetevirens Bright-green Cave-mossDitrichum cornubicum Cornish Path MossDitrichum plumbicola Lead-mossDitrichum subulatum Awl-leaved DitrichumDumortiera hirsuta Dumortier’s LiverwortFissidens curvatus Portuguese Pocket-mossFissidens serrulatus Large Atlantic Pocket-mossFossombronia foveolata Pitted FrillwortFunaria pulchella Pretty Cord-mossGrimmia crinita Hedgehog GrimmiaJamesoniella undulifolia Marsh EarwortLejeunea mandonii Atlantic LejeuneaMarsupella profunda Western RustwortPetalophyllum ralfsii PetalwortRiccia bifurca Lizard CrystalwortRiccia nigrella Black CrystalwortScopelophila cataractae Tongue-leaf Copper-mossTelaranea nematodes Irish ThreadwortTortula cuneifolia Wedge-leaved Screw-mossTortula wilsonii Wilson’s PottiaWeissia multicapsularis Spreading-leaved Beardless-mossSpecies listed on Schedule 8 of the Wildlife & Countryside Act 1981 (asamended)A site is eligible for selection if it supports a significant population of a listed species (thesespecies automatically score 200).Species listed on Annex II of the EC Habitats Directive (1992, as amended)A site is eligible for selection if it supports a significant population of a listed species (thesespecies automatically score 200).Appendix 6 – Species Evaluation in CornwallCounty Wildlife Sites Criteria
Red Data Book (RDB) Species, Nationally Scarce Species and Species of countyimportanceSome Nationally Rare species (see Church et al., 2001) that currently occur in fewer thanten British sites score 200. Other Nationally Rare taxa score 100, as do the rarest of the‘Nationally Scarce’ category. Certain species showing widespread or long-term declines alsoscore 100; however Fossombronia husnotii scores only 50 because it is found on manyCornish sites.Nationally Scarce species (see Preston, 2006) score 50 (Aloina ambigua and Fissidens limbatusare excluded because both are under-recorded and taxonomically weak).Any additional species (or taxa) that are rare in Cornwall (4 or fewer post-1949 records)score 50. However, those that are relatively common elsewhere across at least parts ofsouthern or central England are ignored.A few species that are both rare in Cornwall and otherwise unknown in southern Britain (orwith only one or two other localities) score100 if they do not otherwise qualify for such ahigh score.Tortula acaulon var. papillosum (syn. Phascum cuspidatum subsp. papillosum) and Tortellaflavovirens var. glareicola are both ignored because taxonomy is uncertain and intermediatesare very common.Acaulon minus var. mediterraneum appears to be a Nationally Rare taxon with spiculosespores. An account of its characters and British records is in preparation. The score of 100assumes it to be somewhat under-recorded.For a few dioicous species the presence of both sexes together or of just the rarest sex isused to justify a higher score (100 not 50). indicates Nationally Scarce** indicates County Important (italicised if uncertain)* indicates rare in Cornwall and otherwise unknown in S EnglandAcaulon muticum var. mediterraneum 100Adelanthus decipiens 100Amblystegium radicale 200Ambystegium saxatile = A. radicaleAnomobryum filiforme = A. julaceum**Anomobryum julaceum 50Antitrichia curtipendula 100Atrichum tenellum 50**Barbilophozia barbata 50**Barbilophozia floerkei 50**Bartramia ithyphylla 50**Blepharostoma trichophyllum 50Brachydontium trichodes 50Bruchia vogesiaca 200Bryum apiculatum 100Bryum intermedium 50Bryum torquescens 100Bryum valparaisense 100**Calliergon giganteum 50Appendix 6 – Species Evaluation in CornwallCounty Wildlife Sites Criteria
