Natural Resources Wales is responsible for the sustainable management of the publicly owned woodlands and forests of Wales. They are managed for the benefit and well-being of the people who visit them and depend on them for their livelihood. This responsibility includes improving their biodiversity and long-term resilience to climate change so that future generations will also be able to enjoy the benefits they provide. Every ten years Natural Resources Wales reviews the long-term management plans for each forest area. These are compiled in a new Forest Resource Plan, which set out the long-term vision for these woodlands and are the basis for 10-25-year silvicultural programmes of work (management of the trees) that set out to deliver this vision.

Gethin, Merthyr Vale & Allen's Estate Forest Resource Plan is made up approximately 5 woodlands split between Rhondda Cynon Taf County Borough Council and Merthyr Tydfil County Borough Council and cover an area of 1,365 hectares.

The setting for the woodlands are steep sided valleys close to the communities of Merthyr Tydfil to the North, through Aberfan, Mountain Ash and Troedyrhiw and down to Treharris and Abercynon in the South.

The majority of the FRP extends between the River Taff to the east and River Cynon to the West and sits within the wider Taff Catchment

The FRP provides multiple benefits with some areas providing valuable timber resource, others with a focus on Recreation (i.e. Bike Park Wales) and habitat restoration (Ancient Woodland Restoration, Great Crested Newt habitat, Grassland habitat)
