Dyfi Forest Resource Plan

Dyfi Forest Resource Plan

View and comment on our proposed plans for Dyfi forest


Dyfi forest is situated to the north of the Afon Dyfi and the east of the Afon Dulas on the boundary between Gwynedd and Powys and covers an area of approximately 2955 hectares. Dyfi FRP is one of two pilot plans that are being developed to replace the previous format of forest design plans.

This is a highly productive forest for timber with soils and climate suitable for growing a wide variety of high yielding tree species. The forest is predominantly spruce but also includes higher quality species such as Douglas fir and larch.  To date there has only been a limited impact of Phytophthora ramorum on the larch, but it is accepted that this species will need to be removed in the coming years as part of the larch replacement programme currently being implemented across the Welsh Government Woodland Estate.

Ancient woodland is designated over approximately 430 hectares of the plan area in varying ecological condition from Ancient Semi-Natural Woodland (ASNW), which includes Coed Maes-mawr SSSI, to significant areas of Plantation on Ancient Woodland Sites (PAWS) with few remnant features. There are also significant heritage features throughout the forest such as old mine workings and agricultural features.

There is regular informal recreational use of the forest, particularly from local dog walkers and cyclists on the trails including the Dyfi ClimachX. The forest is also used more formally by Outward Bound, Wales Rally GB and other organised events.

Summary of objectives

  • Managing for water – improvement of riverine habitat, including the gradual reduction of the need for forest harvesting operations in many of the steep difficult terrains associated with these water courses.  Establishing a framework of predominantly native habitat, linking existing ancient woodland, helping to improving water quality and reducing the risk of forest operations impacting on water sedimentation
  • Maintaining timber production - this shall remain a key driver for Dyfi forest, however the opportunities for diversification of tree species are considerable due to the good soils and significant areas that have low enough exposure
  • Management systems on steep terrain which limits opportunities for forest management, systems chosen for management should be appropriate to the site and promote good silvicultural management practices
  • Investment in infrastructure (tracks) will be necessary to support the move to Low Impact Silvicultural Systems (LISS)
  • Much of Dyfi Forest is second rotation conifer crops with large areas in urgent need of high quality thinning interventions that will support the development of LISSs, reduce the need for large scale clearfelling in the future and aid the development of structural diversity of the forest
  • Key habitats for European Protected Species such as Dormice should be protected and enhanced, this again will benefit from an improved delivery of silvicultural thinnings
  • Industrial heritage is a major feature of the area with many features (slate mines) within the forest, these should be protected and it should be ensured that any harvesting work follows best practice
  • Research Forest – This part of Dyfi Forest is now officially part of a GB network of Research Forests where the objective is – “The Dyfi Catchment and Woodland Research Platform will support study of multi-functional landscapes at a catchment scale, where the relative roles of biodiversity, geology, hydrology, geomorphology, soils, vegetation, climate and human activities can be examined in an integrated research and monitoring programme.” - http://www.forestry.gov.uk/fr/INFD-8S6FYH
