encompassing the following
The Mulkear River and its tributaries (principally Newport, Bilboa and Dead rivers) form part of the Shannon Special Area of Conservation (SAC) and are particularly important for sea lamprey, Atlantic salmon, European otter, river lamprey and brook lamprey. The first three of these are the main ecological focus for this project.
The rivers have been extensively modified since the 1850s - straightening and meander removal, along with regular removal of LWD and other vegetation - which has reduced habitat diversity and thus biological diversity - ie. LWD removal reduces pool formation - an important habitat for juvenile Atlantic salmon. In addition, a number of weirs have been installed, creating a barrier to free upstream migration of fish for spawning - particularly sea lamprey and Atlantic salmon.
The riparian zones along the Mulkear and its tributaries have been degrading for many years, contributed to by the spread of invasive species (eg. giant hogweed, Japanese knotweed, Himalayan balsam). This may lead to loss of river bank stability, sedimentation of important spawning beds and in the long term, the health of the riverine ecosystem as a whole.
A number of aims have been set out to improve the in-stream and riparian habitats:
1. Restoration of degraded habitats to improve otter (Action for otters), sea lamprey and Atlantic salmon populations, using best-practice for habitat rehabilitation.
2. Removal/modification of weirs to facilitate upstream fish migration for spawning.
3. Prevention and reversal of damage caused by invasive/introduced species - removal of problem vegetation from riparian zone and replacement of conifers with deciduous trees.
4. Work with local farmers to produce alternative solutions for cattle watering, with less impact on water quality.
5. Extensive advocacy/advisory work to create strong community links, along with improved education and awareness of river-related issues.
Works include: Alternative cattle watering solutions to improve water quality.
