, erosion of the peaty soils' structure, and accelerated drainage.The Pumlumon Project
'A pioneering, science-based project to revive the ecology and economy of the Welsh uplands', Montgomeryshire Wildlife Trust ''www.montwt.co.uk'', accessed 14 April 2022 Some believe the drainage issues have contributed significantly to flooding in areas some distance downstream, though this cannot be clearly proved. Like most of the uplands across Wales, intensive land use activities have resulted in many habitats being either lost or degraded. Over-grazing of sheep has induced soil compaction, which has resulted in increased flooding of the lowland areas. The principal land cover within the project area is dominated by a complex mosaic of locally, nationally and internationally important habitats and species, such as dry and wet dwarf-shrub
