The world pays increasing attention to the conservation and restoration of natural wetlands. In order to maintain the habitats that are important both for the European Union and Latvia, the project “Conservation and Management of Priority Wetland Habitats in Latvia” (Ref.No. LIFE13 NAT/LV/000578) is implemented during 2013 – 2017. The project is funded by the EC LIFE+ program and the Administration of Latvian Environmental Protection Fund. The project is 8 implemented by the University of Latvia and five project partners – RIDemo Ltd., E Būvvadība Ltd., Modern Technology Development Fund, Estonian Fund for Nature (SA Eestimaa Looduse Fond) and Diepholzer Fen Lowland Union (BUND Diepholzer Moorniederung). The project aim is to implement wetland protection and restoration measures to ensure conservation and protection of the habitats that are valuable for Latvia and European Union. The objectives of the project: • At the project sites, to ensure the most favourable status for July 11–12, 2017 – Riga (Latvia) especially protected habitats of Latvian and EU raised bogs, transition mires, fens, and spring fens, including their plant and animal species; • To perform the management of protected mires habitats; to ensure continuous humidity conditions in the mires and to restore the original vegetation, reduce growing areas of invasive Sosnowsky’s Hogweed Heracleum sosnowskyi in spring fens habitats, to clean shrubs in transition mires and fens, to perform long-term observation (monitoring) of changes of mires vegetation; • To organize national and international seminars for the various interest groups, thus contributing to the transfer of experience in the restoration and protection of wetlands’ habitats to the professionals and general public; • To educate the public about the necessity of protection, conservation and management of the mires creating the project website and preparing five informative booklets, as well as creating a mobile interactive multimedia exhibition, photo exhibition and four films. Protected habitats in the project sites: Raised bogs (7110) are habitats getting water and nutrients from atmospheric precipitation. The most common bryophytes are Sphagnum species, which are the main “creators” of the peat bog. Raised bogs have a very few nutrients, because up to 10 m thick peat layer covers the mineral soil and prevents the bog plants to use nutrients contained therein. Degraded raised bogs where natural regeneration is possible or is taking place (7120) are the mires, where the natural hydrological regime has been changed or where part of bog is used for peat extraction. These habitats comprise also the bog areas where the possibility to restore the natural 9 hydrology exists and where peat formation is expected in 30 years. Transition mires and quaking bogs (7140) are habitats that originally are formed in the process of overgrowing lakes or wetlands turning into the mires. They occur on the edges of raised bogs, lakes and boggy depressions (vigas). Petrifying springs with tufa formation (Cratoneurion) (7220) are sites, where springs with calcareous water form freshwater deposits of lime (lime tufa, travertine). They can be found both in forests and in open landscapes. In Latvia could be found very rarely. Mineral-rich springs and spring fens (7160) are the springs and spring fens having constant inflow of groundwater. Depending on the quantity of water flow, they can be found in a form of a little lake, a small watercourse or wetland area with damp soil. Project sites Slītere National Park is especially protected nature area that is established to protect unique inter-dune complex, consisting of 150-180 dunes (kangari in Habitats on Conservation and Management of Wetland Conference Latvian), interspersed between narrow, wet depressions (vigas in Latvian). This unique area is formed 4-7 thousand years ago, when the Littorina Sea covered the territory of Latvia. The largest mire in SNP is Bažu Mire (2646 ha). Frequent rarities that could be found in the wet depressions are oblong- leaved sundew Drosera intermedia, fen orchid Liparis loeselii and rare moss species – Paludella squarrosa, Buxbaumia viridis, Dicranum viride, Drepanocladus vernicosus. Gauja National Park was established to protect the unique nature object, the ancient Gauja River Valley. The current Gauja Valley was formed by derogation of glacier about 12-13 thousand years ago. Almost all ecosystems typical to Latvia, i.e. forests, mires, rivers, lakes, and natural grasslands are common in the National Park. The largest mire in the area is the Sudas-Zviedru Mire (2575 ha) where raised bog habitats maintain rare plant species like deer grass Trichophorum cespitosum. In the other project site, Dāvida Springs by the riverside of Vaide River, rare and protected habitat Petrifying springs with tufa formation (Cratoneurion) occupies area of 3 ha. Ziemeļu Mires Nature Reserve was created for the protection of a large complex of mires. Part of the Nature Reserve is included

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

Moreover, this examination highlights which species appear to be underprotected and therefore need to be included in some catalogues of protection or be catalogued under some category of protection. Te national and regional catalogues that should be implemented are shown, as well as what species should be included within them. Tis report should be a helpful guideline for environmental policies about orchids conservation in Spain, at least at the regional and national level. Around 76% of the Spanish orchid fora are listed with any fgure of protection or included in any red list, either nationally (about 12-17%) or regionally (72%).

  • Carnivorous Plant Responses to Resource Availability
    Carnivorous plant responses to resource availability: environmental interactions, morphology and biochemistry Christopher R. Hatcher A doctoral thesis submitted in partial fulfilment of requirements for the award of Doctor of Philosophy of Loughborough University November 2019 © by Christopher R. Hatcher (2019) Abstract Understanding how organisms respond to resources available in the environment is a fundamental goal of ecology. Resource availability controls ecological processes at all levels of organisation, from molecular characteristics of individuals to community and biosphere. Climate change and other anthropogenically driven factors are altering environmental resource availability, and likely affects ecology at all levels of organisation. It is critical, therefore, to understand the ecological impact of environmental variation at a range of spatial and temporal scales. Consequently, I bring physiological, ecological, biochemical and evolutionary research together to determine how plants respond to resource availability. In this thesis I have measured the effects of resource availability on phenotypic plasticity, intraspecific trait variation and metabolic responses of carnivorous sundew plants. Carnivorous plants are interesting model systems for a range of evolutionary and ecological questions because of their specific adaptations to attaining nutrients. They can, therefore, provide interesting perspectives on existing questions, in this case trait-environment interactions, plant strategies and plant responses to predicted future environmental scenarios. In a manipulative experiment, I measured the phenotypic plasticity of naturally shaded Drosera rotundifolia in response to disturbance mediated changes in light availability over successive growing seasons. Following selective disturbance, D. rotundifolia became more carnivorous by increasing the number of trichomes and trichome density. These plants derived more N from prey and flowered earlier.

  • Schoenus Clade (Cyperaceae): Taxonomy, DNA Barcodes and Genome Evolution
    Schoenus clade (Cyperaceae): taxonomy, DNA barcodes and genome evolution A.M. Muasya, University of Cape Town FBIS160530166740 The African and Australasian genus Tetraria is polyphyletic and dispersed into four lineages, with the two South African lineages informally recognized as comprising the Tricostularia and Schoenus clades. Species boundaries in the Schoenus clade are uncertain because of character similarities, possible polyploid origin of narrowly distributed taxa and limited attention by both plant collectors and taxonomists. From broad studies, there is evidence of complex evolutionary relationships within the Schoenus clade, and as currently defined, the clade is polyphyletic and includes the genera Schoenus, Tetraria and Epischoenus. The Schoenus clade has at least 40 taxa endemic to South Africa, with distributions predominantly in the Fynbos biome and extending into the Drakensberg escarpment (but part of the clade also occurs in Australia and New Zealand). This study aims to increase our understanding of the taxonomy and species distributions of Schoenus clade species, to: 1) revise the taxonomy and generate Encyclopaedia of Life (EoL) pages; 2) augment current herbaria specimens of plants from this clade and revise conservation status of all species using the IUCN criteria; 3) acquire genome size data for these species; 4) obtain and publish DNA barcodes for all the South African species in tribe Schoeneae; and 5) improve the understanding of evolutionary relationships within the clade. Field and herbarium studies will run from September 2016 until August 2017 to revise the taxonomy of these species and update their geographical extents. Data on chromosome numbers, genome sizes and genetic (DNA barcode) sequences will be extracted from samples collected in the field to better understand role of polyploidy (and perhaps hybridization) and evolutionary relationships within the clade.

Without limiting the rights under copyright reserved above, no part of this publication may be reproduced, stored in any type of retrieval system or transmitted in any form or by any means (electronic, photocopying, mechanical, recording or otherwise) without the permission of the copyright owner. INTRODUCTION The Selection Criteria are substantially based on Guidelines for selection of biological SSSIs published by the Nature Conservancy Council (succeeded by English Nature) in 1989. Appropriate modifications have been made to accommodate the aim of selecting a lower tier of sites, i.e. those sites of county and regional rather than national importance. The initial draft has been altered to reflect the views of the numerous authorities consulted during the preparation of the Criteria and to incorporate the increased knowledge of the County's habitat resource gained by the Phase 1 Habitat Survey (1992-97) and other survey work in the past decade.

  • The Red Data List of Irish Plants
    The Red Data List of Irish Plants The risks that species face are each very different, however, as a guide to the susceptibility of a given species, an agreed set of categories has been established internationally, and these are used to determine the potential risk that a species could become extinct. These categories are:- CRITICALLY ENDANGERED or CR - Species that are declining at a fast rate, and face imminent risk of extinction. ENDANGERED or E - Species that are declining, or grow in habitats likely to be disturbed, 'developed' or facing an ongoing degradation. VULNERABLE or V - Species that are currently not endangered, but would be extremely vulnerable if their habitats are disturbed in the future. There are seven species of plant that require immediate intervention (CR) if we are to save them from joining the fate of 11 other species that are now known to be extinct in Ireland. A number of these are already extinct in the Republic, and are not therefore legally protected under the 1999 Flora Protection Act. In the list below, 188 species of plant are listed, of which 64 are flowering plants, 4 ferns, 14 mosses, 4 liverworts, 1 lichen and 2 algae.

  • Carnivorous Plant Newsletter Vol 48 No 4 December 2019
    Drosera in the western USA—an update Barry A. Rice • Center for Plant Diversity • University of California • One Shields Avenue • Davis • California 95616 • USA • [email protected] Keywords: Taxonomy: Drosera, western USA, Drosera anglica, Drosera intermedia, Drosera linearis, Drosera × obovata, Drosera rotundifolia, Drosera × woodii. One of my primary research activities focuses on carnivorous plants in the US states of Montana, Wyoming, Colorado, New Mexico, and westward (but excluding Alaska). Throughout most of this range, the only native species of Drosera are Drosera rotundifolia L., Drosera anglica Huds., and the hybrid Drosera × obovata Mert. & Koch. These species are well-known to readers of this jour- nal, and need no further description. In this region, these plants quite often occur in sites that are widely separated, and in some states these taxa are of considerable rarity (for example, in Colorado D. rotundifolia and D. anglica are known at only 4 and 1 sites, respectively; Wolf et al. 2006). In addition to these species, there have been reports of two additional native Drosera—Drosera intermedia Hayne in northern Idaho (and perhaps adjacent eastern Washington), and Drosera lin- earis Goldie in Montana. Drosera intermedia was reported in Boundary County, Idaho by Bursik (1993), as growing with Drosera anglica, but being quite different in form. Additional populations were subsequently found in Custer County, Idaho (L. Kinter, pers. comm. 2017). Of course, the closest other Drosera inter- media plants were on the other side of the continent, so this was considered a find of great interest, and the plants were treated as of special significance. A few years ago, I decided I needed to visit and assess these plants.

  • In Vitropollen Germination of Orchids Traditionally Used
    148 European Journal of Environmental Sciences IN VITRO POLLEN GERMINATION OF ORCHIDS TRADITIONALLY USED TO PRODUCE SALEP YASEMIN KEMEÇ1,*, KAAN HÜRKAN1, and CÜNEYT AKI2 1 Çanakkale Onsekiz Mart University, Institute of Natural and Applied Sciences, Department of Biology, 17100 Çanakkale, Turkey 2 Çanakkale Onsekiz Mart University, Faculty of Science and Arts, Department of Biology, 17100 Çanakkale, Turkey * Corresponding author: [email protected] ABSTRACT In Turkey the tubers of about 120 orchid species are widely collected for manufacturing the traditional drink salep. In this study, we focused on the in vitro germination of the pollen of the salep orchid species Ophrys mammosa, Orchis provincialis, Anacamptis morio subsp. morio, Orchis simia and Neotinea tridentata and discussed the potential effects this might have on the conservation of these orchids by reducing the need to collect them in the field. Pollen was sown on different media; Knudson, Orchimax and the medium described by Malmgren, and then incubated at 24 ± 1 °C in darkness for 24 h. Germinated pollen was stained with Brilliant Blue and examined under a stereoscopic microscope. Results of Tukey and Dunnett T3 statistical tests indicated that in terms of percentage germination, the best germination was observed on O. mammosa by 55% and Orchimax was the most successful medium by 50.5%. For pollinaria germination, the best rate was observed on O. mammosa by 69%. The medium Malmgren was the best germinative by 61.3%. It is clearly seen that difference in germination rates among studied species are achieved using different media. The development of such a method of studied species in this research points to the fact that this is possible and should serve as encouragement for others to devise procedures for other species.

  • Native Plant List, Pdf Format
    Appendix A: City of Bellingham Native Plant List December 2020 The City of Bellingham Native Plant List (Figure 1) includes plant species that are native to Bellingham watersheds (Figure 2). The native plant list applies to all habitat types, including riparian, upland, and wetland areas. The list was developed using specimen records from the Consortium of Pacific Northwest Herbaria and Bellingham plant checklists curated by Don Knoke, a volunteer at the University of Washington Herbarium. To improve plant establishment and protect the genetic resources of our local plant populations, the City recommends using native plants that were grown from seeds or cuttings collected from the Puget Trough Ecoregion (Figure 3). Obtaining native plants grown from material collected from the Puget Trough Ecoregion will help ensure the plants are adapted to the unique environmental conditions of Bellingham watersheds and are genetically similar to our local plant populations. A more thorough discussion of the rational and selection process is provided in the City of Bellingham Public Works Department Native Plant Materials Selection Guidelines, December 2020. Figure 1.
