Widespread death of a tree species will have ecological impacts on species that in some way depend on that tree species to complete their life-cycle. One measure to mitigate these impacts is to establish alternative tree species to replace the threatened tree species. These alternative tree species should be as similar as possible to the threatened tree species in terms of species supported, tree traits and the environmental conditions under which the tree will grow. This study assesses the availability and quality of data to assess the ecological impact of Hymenoscyphus fraxineus on Fraxinus excelsior and the suitability of 48 alternative trees to replace F. excelsior in the UK. To make this assessment data were collected on 1) species use (whether the 955 ash-associated species will use the alternative tree species), 2) traits (bark pH, deciduous, floral reward, fruit type, height, leaf dry matter ...

Status notes give short explanations, justifications, references, etc. for country occurrences in the distribution tables. Taxon details list the naming authorities for each taxon and provide notes and references on nomenclature and synonymy. Nomenclature follows the recently published annotated checklist of bryophytes of Europe, Macaronesia and Cyprus. An extensive bibliography and literature list are provided, followed by an appendix with useful references for Europe as a whole, European regions and individual European countries or territories. Appendices with lists of European bryological societies, journals, floras and the country contacts of the European Committee for Conservation of Bryophytes are presented at the end of the report.

However, there is still a substantial problem in encouraging individuals and agencies to use the revised system, and there are still many different systems currently in use, both within individual countries and internationally. A British initiative to provide a common standard for assignation of conservation status to species in Britain is described. It emphasises the importance of using the same, stable, criteria throughout, engaging the available expertise and reporting effectively.

The first edition, published in 1995, is now in urgent need of updating. Since its publication, our knowledge of the bryophytes of Europe has been considerably improved, especially concerning taxonomy and distribution. The work has started: a comprehensive table, listing the occurrence and Red List status of each species, in each European country, has been prepared. A short list of candidate species for IUCN threat assessment was established by eliminating species known with certainty to be of least concern. Of 2140 bryophyte species known to occur in Europe, 241 liverworts and 721 mosses were selected for further consideration. Among them, 28 liverworts and 98 mosses occur in Hungary. Examples of some species occurring in Hungary are presented below to show which criteria are u...

H. vernicosus, commonly known as the Slender Green feather-moss, has distinctive hooked shoot tips and leaves that are strongly curved, are often pleated lengthways and are frequently tinged with red at the bases. It occurs in mesotrophic fens and flushes. H. vernicosus can appear similar to other fen species, such as Warnstorfia exannulata and in the past has also been confused with other species, such as Scorpidium cossonii and Palustriella commutata. H. vernicosus is dioicous and sporophytes are rare across its distribution and have never been reported in Ireland. It has a circumboreal distribution and although widespread in Europe, it is rarely common. It is scattered and rare in the Republic of Ireland, with 11 extant populations in the counties of lowland transition m...

Most of the information openly available has been published by the Ghana Herbarium at the Department of Plant and Environmental Biology, University of Ghana. The Ghana Herbarium has over 100,000 specimens from Ghana and other West African countries. Of these approximately 85% of the specimen labels have been digitized. The database contains information including species names, taxonomic family, barcode number, name of collector(s), locality data, date of collection, description of species and uses of the plants. Data were captured using Botanical Research and Herbarium Management Software (BRAHMS) software and is openly available on Global Biodiversity Information Facility (GBIF) (http://www.gbif.org/country/GH/publishing). Less than 1% of the herbarium collection contains bryophyte information of Ghana. Even though bryophytes are an often overlooked flora, Ghana has a high diversity of bryophytes. Indeed Ghana...
