While seemingly in a natural state, the rivers was incised and disconnected from the wider flood plain, with a lack of suitable gravels for the resident native Brown Trout population. Felling commenced in 2018 and some of the timber was used to begin ditch blocking and creating leaky dams within the main channel. Early observations showed that the results had been positive with the hydrological systems soon renaturalising within the valley floor, wet areas were developing and the main channel began to take on a more braided characteristic by occupying historic channels. In channel flow diversity increased markedly allowing a more complex sediment matrix to appear.<br /> |Monitoring surveys and results=Pre work aerial studies of the area and fixed point photography at key areas through the valley have allowed a gross study of early geomorphological changes within the system, including stream number and width, and changes within the netweork of wet areas across the valley floor.<br /> Aberystwyth University are undertaking flow measurements and will continue to do so over an extended time period. Ecological studies will be undertaken across this and a control site on the same waterbody to monitor changes.<br /> |Lessons learn=The implementation of this scheme on Welsh Government Woodland Estate has shown that there are high value gains possible at low cost inputs which can be imnplemented alongside current Forest management techniques. These can yield multiple benefits and studying these allows us to put forward a case for spreading this work and ethos across the wider Woodland Estate with potential for large scale projects. The multiple benefits are closely aligned with NRW's wider Corporate and Business plans and better ways of working which look to generate positive outcomes through nature based solutions giving positive benefits across a broad spectrum of habitats, species and communities.<br /> |Project title=Afon Merin Natural Process Restoration<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Merin2.jpg<br /> }}<br /> {{Case study image<br /> |File name=Merin3.jpg<br /> }}<br /> {{Case study image<br /> |File name=Merin4.jpg<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site}}<br /> {{Project background}}<br /> {{Motivations}}<br /> {{Measures}}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>
