Life Conference: Cors Geirch

I did not attend the trip to Cors Geirch, but that doesn't mean it's not an important wetland in the North Wales area. This site is situated on the Llyn Peninsula in a valley that lies between Pwllheli and Nefyn. Much like the other sites visited during the LIFE conference the reserve is recognized as a SSSI, SAC and also protected by RAMAR.

It is another fen site that is fed by alkaline water that drains into through the surrounding porous limestone rock making it a rare type of wetland. The site is also managed by CCW, and Welsh Mountain ponies are used to graze the site.
The site is special as it was the first in Wales to have the rare Narrow-leaved Marsh Orchid identified in 1953, it has now been identified at Cors Bodeilio and Cors Erddeiniog.
Many fenland species which were also see the at other sites we visited were present at Cors Geirch which can be seen listed on the Countryside Council for Wales website.
In the early 90s the site went through a large scale restoration project removing the top 30cm of peat across a large area of the site. The results included a raised water table and reduced fertility, allowing fen plant species to recolonise where agricultural species once dominated. More information on peat re profiling can be found on the LIFE project website.
