  • Biology, Genetic Variation and Conservation of Luronium Natans (L.) Raf
    Watsonia 22: 301-315 (1999) 301 Biology, genetic variation and conservation of Luronium natans (L.) Raf. in Britain and Ireland Q. O. N. KA Y, R. F. JOHN School of Biological Sciences, University of Wales, Swansea SA2 8PP and R. A. JONES Countryside Council for Wales, Ladywell House, Newtown, Powys SY161RD ABSTRACT Luronium natans (Floating Water-plantain) is a European endemic aquatic plant which is now rare and threatened across most of its extant range. Confusion with similar species has led to misunderstanding of its distribution and status in Britain and Ireland, but oligotrophic upland lakes now seem to hold the main populations. Isozyme studies show comparatively high levels of genetic variation among native populations in Wales, contrasting with the lack of variation reported in some closely-related aquatic species, but there is close similarity among samples of plants from canal populations on the Welsh borders. It has spread into this canal habitat relatively recently (post-l 850), and the isozyme patterns found there indicate that the canal populations have originated from a native lake population connected to the canals by feeder streams. The greatest range of genetic variation now appears to remain in a few native "core" sites, and the survival of these populations is thus of particular importance. Conservation priorities are discussed in relation to the biology, distribution and metapopulation structure of the species in Britain and Ireland. KEYWORDS: Floating Water-plantain, aquatic plants, isozyme variation, Wales, threatened species, oligotrophic lakes. INTRODUCTION Luronium natans (L.) Raf. (Alismataceae) is a stoloniferous aquatic perennial which grows in a range of habitats, and is phenotypically very plastic.

    WETLAND PLANTS – full species list (English) RECORDING FORM Surveyor Name(s) Pond name Date e.g. John Smith (if known) Square: 4 fig grid reference Pond: 8 fig grid ref e.g. SP1243 (see your map) e.g. SP 1235 4325 (see your map) METHOD: wetland plants (full species list) survey Survey a single Focal Pond in each 1km square Aim: To assess pond quality and conservation value using plants, by recording all wetland plant species present within the pond’s outer boundary. How: Identify the outer boundary of the pond. This is the ‘line’ marking the pond’s highest yearly water levels (usually in early spring). It will probably not be the current water level of the pond, but should be evident from the extent of wetland vegetation (for example a ring of rushes growing at the pond’s outer edge), or other clues such as water-line marks on tree trunks or stones. Within the outer boundary, search all the dry and shallow areas of the pond that are accessible. Survey deeper areas with a net or grapnel hook. Record wetland plants found by crossing through the names on this sheet. You don’t need to record terrestrial species. For each species record its approximate abundance as a percentage of the pond’s surface area. Where few plants are present, record as ‘<1%’. If you are not completely confident in your species identification put’?’ by the species name. If you are really unsure put ‘??’. After your survey please enter the results online: www.freshwaterhabitats.org.uk/projects/waternet/ Aquatic plants (submerged-leaved species) Stonewort, Bristly (Chara hispida) Bistort, Amphibious (Persicaria amphibia) Arrowhead (Sagittaria sagittifolia) Stonewort, Clustered (Tolypella glomerata) Crystalwort, Channelled (Riccia canaliculata) Arrowhead, Canadian (Sagittaria rigida) Stonewort, Common (Chara vulgaris) Crystalwort, Lizard (Riccia bifurca) Arrowhead, Narrow-leaved (Sagittaria subulata) Stonewort, Convergent (Chara connivens) Duckweed , non-native sp.
