Welsh wetland turned over to wildlife

WETLAND HAVEN: Bwlch Cefn Llian

Home to otters, wagtails and snipe

December 2011: What do you do with an area of woodland that doesn't like trees?

That was the conundrum facing Forestry Commission Wales after trees refused to grow on an area of Bwlch Cefn Llian woodland, just north of Rhayader in mid-Wales.

Attempts some time ago to restock about 3.5 hectares with mixed broadleaves and sitka spruce failed due to the wet conditions, so foresters came up with the perfect answer - create a wetland haven for endangered wildlife.

Creating this area has been immensely satisfying
Forestry Commission Wales joined forces with Environment Agency Wales and Radnorshire Wildlife Trust to improve the biodiversity of the forest by blocking overgrown drainage ditches, encouraging surface water to spread across the area.

Wetlands are fast disappearing habitats but provide sanctuaries for rare insects, animals and birds such as dragonflies, otters, warblers, wagtails and snipe.

The woodland area proved the perfect location for a wetland as it could be converted with little work and lay within the River Marteg catchment area, where the Wildlife Trust is already working on several projects.

Nick Whythe, Forestry Commission Wales Local Area Manager, said: ‘The area was unsuitable for commercial tree planting but, through this partnership, we have been able to increase the environmental and biodiversity value of what would otherwise be an area of unproductive woodland.

Work will reduce the risk of flooding
‘Wetlands and their associated fauna and flora are becoming rarer all the time in rural areas due to agricultural and forestry drainage, so creating this area has been immensely satisfying.'

Conversion of the site to a wetland took about a week and involved blocking about 400 metres of drains. The work will also reduce the risk of flooding in the River Marteg by slowing the flow of rainwater into the river, as well as slowing the release of carbon from the peat in the area by blocking off the air to the surface.

Catrin Grimstead, the biodiversity officer for Environment Agency Wales, said: ‘Wetlands are very special. As well as providing habitats for some of our most threatened wildlife, they act as sponges, helping to reduce the impacts of flooding and drought, and promoting healthy environments downstream.'

Darylle Hardy, of Radnorshire Wildlife Trust, described the habitat enhancement work was ‘an exciting new beginning'. She said: ‘Already, snipe have found the newly-wetted hollows but we're expecting to see other wetland birds, more amphibians, dragonflies, signs of otters and maybe even water voles in the future.'
