Pearl Mussel Conservation beyond the Pearl Mussel Project

The Irish Pearl Mussel Project is looks agricultural impact and looks at 80% of the population.

To consider other (non-agricultural) threats, and 20% of Pearl Mussel populations outside the 8 Project catchments needs more consideration.

Summary on conservation status of Pearl Mussel species (Page 51):

Reports on the conservation status of habitats/species protected under the Habitats Directive, are made to the EU every six years, and all three summary and detailed background reports are available at:

https://www.npws.ie/publications/article-17-reports

These include some information on pressures and conservation measures.

A map identifying the water catchments within which populations of the Freshwater Pearl Mussel occur can be found on the following web page as both a GIS shapefile and as a pdf (entitled ‘Margaritifera Sensitive Areas map’)

General Information on NPWS

There is also information on the species on npws.ie, (may need to be updated)

See

https://www.npws.ie/research-projects/animal-species/invertebrates/freshwater-pearl-mussel

Which has links to a series of pages, including this page

https://www.npws.ie/research-projects/animal-species/invertebrates/freshwater-pearl-mussel/irish-sacs

That lists the 19 SACs designated for the protection of the species, and :

https://www.npws.ie/research-projects/animal-species/invertebrates/freshwater-pearl-mussel/conservation-measures

That gives some information on conservation measures, including Regulations made in 2009 to protect 27 mussel populations in those 19 SACs

Interested in local knowledge on Pearl Mussel population, non-agricultural threats and any local citizen science / research on populations within or outside the Pearl Mussel Project.
