Rare & threatened fern and fern allies conservation and monitoring

The Rare and threatened fern and fern allied species in Ireland under investigation include Killarney Fern (Trichomanes speciosum), Clubmosses (Lycopodiaceae species) and Moore’s Horsetail (Equisetum x moorei). This is collaborative project between NPWS Scientific Unit, Trinity College Dublin Botany Department and the National Botanic Gardens Glasnevin.

  • To develop practical monitoring guidelines for reporting on these species to the EU under Article 17 of the Habitats Directive.
  • To develop methods for best conserving these species in the wild and in long-term storage (ex situ) as backup collections.
  • To determine the genetic makeup of populations of the Annex I species Killarney Fern (Trichomanes speciosum) using a DNA fingerprinting technique.

Bryophyte Conservation

There have been a number of NPWS bryophyte conservation projects completed in recent years including the publication of a Flora Protection Order Map Viewer – Bryophytes. Other useful resources include:

Other on-going bryophyte projects include:

  • New bryophyte Red List for Europe, a three-year project led by IUCN, supported by EU LIFE funding (LIFE14 PRE BE 001) and co-financed by NPWS. See and for further information.
  • Calaminarian Grassland Survey 2017-2018 (Hodd and Hodgetts, consultants), with a particular focus on metallophyte bryophyte species.
  • Rare Plants Monitoring project (BEC consultants), which includes survey, monitoring and reporting for EU Habitats Directive Article 17 bryophytes Petalophyllum ralfsii and Hamatocaulis verniciosus.

Scapania ornithopodioides


The LichenIreland project, in conjunction with CEDaR and the Environment and Heritage Service Northern Ireland, was initiated in 2005. This project aims to increase awareness of the species group, as well as improve understanding of the distribution and ecology of the Lichen flora in Ireland.
