Bog on Leitrim mountain in need of urgent remedial work

Bog on Sliabh an Iarainn

The blanket bog on the summit of Sliabh an Iarainn mountain is in need of restoration.

Simon Gray, Senior Technical Officer at Ulster Wildlife who is working on the restoration of the blanket bog on Cuilcagh told the Leitrim Observer there may be scope to extend their works into Leitrim, if funding is received.

He told the paper "a huge area on the summit of Slieve Anierin requires remedial work."

Work is ongoing on Cuilcagh mountain in Cavan/ Fermanagh to restore 16Ha of degraded blanket bog.

Mr Gray explained "The area of blanket bog we are working on has been badly eroded at some point in the past which has exposed large areas of bare peat and left hags of peat lying proud. The reason why this erosion has occurred is still up for debate. When we see this kind of erosion it can be down to a number of things including fires, overgrazing, peat cutting, visitor numbers, drainage, extreme weather events and unique natural events. 

"In this case we are not sure why it appeared but something had to expose the bare peat in the first place to allow water, wind, freeze thaw and drought to erode it to the extent it is now in. It may have been a fire or something some time ago. 

The works started on Cuilcagh in September and is using peat hags to revegetate the cliffs of bare peat. They are also blocking the gullies with coir logs, the works will continue until the new year. The area will then be monitored to see how it works and if it could be replicated to success in other areas.

The entire project is costing approx £100K.

A larger part of South Leitrim including Slibah an Iarainn is included int he same Special Area of Conservations (SAC) as Cuilcagh. The current project is working on a conservation action plan will be developed for the whole SAC and this will identify the exact areas where this kind of work will be warranted.

"We are having conversations with NPWS at the minute about what ways we might be able to find funding for these kind of works in the future and what way we can involve landowners in the area. Very early days at the minute but we are doing our best to try and put this area on the map for funding for this kind of work. There is actually an area on the south side of Benbrack heading towards Doon (Aughnasheeliin) that requires this kind of work too. We would be really keen to hear from any landowners that would be willing and interested in doing this kind of work.
