An autumnal small leaved lime and upland oak wood

A weather forecast for the Brecon Beacons National Park stated fog/mist/low cloud, light rain and negligible wind, so it was with high hopes that I set off for Coed y Rhaiadr, there was fog, negligible wind and light drizzle all the way there until I dropped down to Hirwaun. Where there was no fog, mist or rain and the rotating blades of wind farm turbines indicated wind too. Still there are plenty of options in Coed y Rhaiadr with autumnal colour and I headed for an area of woodland high up the ravine slopes with photogenic veteran oaks. Passing the waterfalls the area is noted for indicated the the tree canopy that provide a backdrop had been stripped of leaves from the recent passage of Storm Ophelia. The oaks I had hoped to photograph were also denuded of leaves, so it was back down to the river.



The numerous waterfalls make it a magnet for photography workshops in the autumn and it hadn't taken long for the workshop providers and punters to stake out their claims. I didn't see anyone photographing the woodland sans waterfalls, which is a pity as the woodland is designated as a Special Area of Conservation. A riparian small leaved lime in autumnal colour provided the necessary inspiration and a native woodland tree that I've rarely found a) in autumn colour and b) suitably sited to make a photograph. From the chosen viewpoint the rain serendipitously broke up the river surface, mitigating the sky reflection. Whilst waiting for the wind to ease I watched a Dipper working its way downstream, diving and feeding from the riverbed. The wind eventually died down to make a photograph and the only audible sound was rain falling and dripping down through the canopy.


Another storm was forecast in a few days time so I made the decision to maximise my photography opportunities and cut short my excursion in Coed y Rhaiadr to visit a nearby upland wood that should have been relatively sheltered from the Storm Ophelia's winds. Some parts of the wood have a closed canopy whilst other parts are more open in nature and mature sessile oaks are spread along a steep sided valley, with crowns and branches shaped by the elements. A few oaks have layered their branches which are mantled with epiphytic lichens and well within tripod height.



Birch, alder, willow, holly, hazel, hawthorn, ash and rowan trees make up the rest of the woodland trees and with more time I would have photographed these, but the oaks were concentrated on for this visit. I do not know anything of the woodlands history, many of the oaks are pollarded and the hazel trees are coppice stools, hinting at a past management regime. The wood is not officially designated as ancient woodland, but is depicted on first edition 19th Century Ordnance Survey maps and some of the oaks appear to be of some age. The lack of regeneration indicates the woodland is overgrazed and has been so for many years.


Eventually the wind and driving rain brought an end to the excursion and a note made to revisit again in the future.
