Project Title:

Forest Restructuring in Freshwater Pearl Mussel catchments

Project Coordinator:

Dr. Norman Allot

Project Abstract

Eight of Irelands 27 Freshwater Pearl Mussel (FPM) catchments currently contain 80% of the total national FPM population, representing about 37% of the endangered, population. Ireland, thus, has significant international responsibility for the world’s remaining, critically conservation of the species and as such these ‘Top 8’ catchments have recently become prioritised for implementation of forestry measures to help restore FPM to ‘favourable’ conservation status, as required under the EU Habitats Directive. Forestry is a significant land use in the Top 8, and has been identified, amongst other land uses, as a potential diffuse sources of water pollution which can negatively impact on FPM through the processes of eutrophication and sedimentation. In the absence of specific strategies and measures to improve water quality and FPM habitat, conservation prospects for the species are very poor. To address this deficit, the development of FPM Catchment Strategic Plans for Forestry are now required, As part of that process, the Forest Service recently revised site risk assessment standards for the Top 8 in December 2010. What is currently lacking is an appropriate range of practical mitigation, and future silvicultural and management options to match the identified risks of forestry with the ecological quality objectives for FPM (S.I 296 of 2009). This desk study will provide essential background information on appropriate mitigation and forest management measures to aid the development of FPM Catchment Strategic Plans for

Forestry within the Top 8 with the aim of enhancing conservation of FPM.
