| dc.description | This report presents details of a 2015-2017 monitoring survey to assess the conservation status of the EU Annex II species Hamatocaulis vernicosus, commonly known as Slender Green Feather-moss, which is found in mesotrophic fens and flushes in Ireland. Assessments of Population, Habitat for the Species and Future prospects, were undertaken at all 11 known sites following an established monitoring protocol. Population was assessed at each site using three attributes: extent of occurrence, mean percent cover of H. vernicosus and density of shoots. Habitat for the Species at each site was assessed taking both the area and quality of suitable habitat into account. At each monitoring stop, Habitat for the Species quality assessment data were collected on hydrology, percent tree cover, percent shrub cover, percent grass cover, percent bryophyte cover, cover of Calliergonella cuspidate and mean vegetation height (cm). Pressures, threats and activities, both positive and negative, occurring throughout each site were also examined and used to determine the Future prospects of the site with regard to its Population and Habitat for the Species. Each site received an assessment of Favourable (green), Unfavourable-Inadequate (amber) or Unfavourable-Bad (red) for each of the three parameters, which were then combined to evaluate the overall condition assessment result for the site. Nine sites passed the Population assessment. The failure at two sites could be linked to drainage activities in parts of the sites. All of the sites received a Favourable assessment for Habitat for the Species, apart from one upland flush site, which failed due to overgrazing of the habitat surrounding the flush. The Future prospects of the Population and Habitat for the Species parameters were assessed at each site, taking pressures, threats and activities into account. Grazing was recorded at most sites and was usually considered beneficial at appropriate levels, although some poaching and erosion was noted at two sites. Damaging drainage activities were recorded at two sites, but the prospect of recovery is deemed to be good if no further drainage activities take place. Combining the assessments of the three parameters at each site resulted in ten sites receiving an overall assessment of Favourable, while one site, received an Unfavourable-Inadequate assessment. At the national level, the Population parameter received a Favourable assessment. Only parts of two sites that failed the Population assessment were negatively affected by drainage and there are good prospects for recovery in these otherwise large populations. Ten of the sites (c. 90%) containing over 99% of the area of the Habitat for the Species achieved a Favourable result for Habitat for the Species, and the Future prospects of Habitat for the Species was assessed as good for the sites deemed to be in Favourable condition. Combining these results, the national conservation status assessment for the Annex II species Hamatocaulis vernicosus was then evaluated, and a result of Favourable was obtained. The report concludes with recommendations for refining the methodology in future monitoring cycles and for improving the conservation status of the less favourably scored sites.
