Croeso pawb.
Nice to see the weather has finally broken from the gloomy, but thankfully dry phase it has been in for a while.
Natural Resources Wales have just completed the remedial and enhancement works to the peat bog at Llyn Llech Owain, I'll give an outline of the why's and what's.
In around 2019 work as carried out by contractors to mitigate the loss of water from the northern section of peat bog, with bunds and pools created to reduce the water runoff. The work seemed to have done the trick, however in 2023 with NRW having conducted a Lidar survey, (Lidar - Wikipedia) it was discovered that the 2019 works hadn't had the overall effect that it could have with the use of modern technology and changes, through learning, of peatbog management.
The work carried out through October and into November has been guided by the latest technology and best practices for peatbog restoration with a major component being to follow the natural contour lines of the land
An experienced and specialist contractor was appointed by NRW, using specialist equipment to access the bog the machinery each had less than 1psi, less than a human footprint.
The first stage was to remove or kill off any scrub in the planned work area, with this complete they set about following within centimetres the creation of bunds and ponds. I think the photos will say a lot more than words can.
The machine clears the ground vegetation then digs in to collect peat, created a bund then turfs over the exposed peat to exclude drying out and erosion
The completed bund then begins to hold water.
We are fortunate that there is a good population of the very important Sphagnum Moss on site which can be "seeded" into any bare ponds in the future.
Even during the work, Common and Jack Snipe were recorded using the reworked areas which was really good to see.
