| dc.description | Since 2004, NPWS has been conducting monitoring, or surveillance, of the Freshwater Pearl Mussel
under Article 11 of the Habitats Directive. This Irish Wildlife Manual documents the monitoring
methods used. These have been developed for Ireland by Freshwater Pearl Mussel experts. In 2009,
Regulations (S.I. 296 of 2009) were made to set environmental quality objectives for listed Freshwater
Pearl Mussel SAC populations. The schedules to the regulations, and the site-specific conservation
objectives, as well as the NSAI standard, form the basis for assessment of conservation status/condition using monitoring data.
This manual provides methods for repeat monitoring of numbers of adult mussels at varying densities.
It also describes the measurement of mussels, with searches for juveniles, used to produce demographic profiles that are essential to assessing the viability of a population. Searching for juveniles carries very high risk of injury or death to mussels, and damage or destruction of their habitat and, therefore, requires specific expertise. | en |
