Current Status in the SW

Definition1

Semi-natural ash woodland on calcareous substrates with associated maple, small-leaved lime, elm and oak, and may be ancient or secondary in origin.

Three broad types are recognized in the Region:

  • Ash-maple woods in the lowlands on calcareous clay
  • Ash woods on the upland fringes on moist but free draining soils, usually present in small stands on flushed soils in oak woods and often associated with alder.
  • Ash-lime woods on steep rocky slopes and in ravines, often associated with species rich limestone grassland.
There is also complementary coverage within other Habitat Action plans for the region including wood pasture and parkland, and upland oakwood.

Current Extent1

It is estimated that the South West holds 10% of the total ancient ash-maple woodland resource in the UK. The area of secondary woodland is currently unknown.

Examples of important sites in the South West1

  • Draynes Wood (Cornwall)
  • Bovey Valley Woods, Lemon Valley, Chudleigh Caves (Devon)
  • Axmouth-Lyme Regis undercliffs (Devon)
  • Purbeck Ridge (Dorset)
  • Cranborne Chase (Dorset/Wilts)
  • Wye Valley (Gloucestershire)
  • Neroche Forest (Somerset)
  • Thurlbear Wood (Somerset)
  • Blackdowns (Somerset)
  • Mendip Complex (Somerset)
  • Avon Gorge (Somerset)
  • Gordano Valley (Somerset)
  • Cheddar Gorge (Somerset)
  • Oxford Clay (Somerset)
  • Park Wood (Somerset)
  • East Exmoor Valley Woods (Somerset)
  • Brayden Forest (Wiltshire)

Current factors affecting the habitat in the SW

  • Presence of planted conifers
  • Lack of continuity of lichen habitat i.e. age structure and successor trees
  • Inappropriate management and or lack or management
  • Fragmentation and isolation of woods.
  • Inappropriate planting and restocking.
  • Lack of suitable markets for coppice products.
  • Increasing deer population preventing regeneration
  • Development e.g. mineral extraction

 


UK biodiversity objectives and proposed targets

Ash and maple woods are addressed within the wider UK - Broadleaved and Yew Woodland Habitat Statement

Conservation Direction: Maintain the extent and habitat quality, especially of ancient and semi_natural broadleaved woodland, and expand broadleaved woods, particularly with new native woodland which is linked to ancient and semi-natural woods.


South-west biodiversity objectives and proposed targets

OBJECTIVE 1

Minimise any further loss of ancient ash-maple woodland

TARGET: Ongoing



OBJECTIVE 2

Ensure that all semi-natural ash-maple woods are appropriately managed for wildlife, to maintain local distinctiveness, to meet local needs


TARGET: ongoing

OBJECTIVE 3

Increase the area of ash-maple woodland by 10% through removal of conifer on ancient sites

TARGET: by 2010



OBJECTIVE 4

Increase the area of ash-maple woodland by 10% through new planting expanding existing woods, targeting links between existing semi-natural habitats.

TARGET: by 2010

OBJECTIVE 5

Promote a campaign for the use of locally sourced wood, including coppice products, especially by promoting the value of ash, e.g. for furniture making

TARGET: by 2000

 




Current Action

Most of the Ash-maple woodlands in the region are designated SSSIs and/or have NNR status; two proposed SACs exist; Wye Valley Woods, and the Avon Gorge Woods

The Forest Authority has a new national census of woodland underway which will provide data by county. It is being carried out on a rolling basis and should reach the region this year. The Authority offer grant aid (WGS/WIG/Challenge Funding) for the management, restocking, restoration and planting of new woods; grant-aid for fencing to exclude stock from woods is also available e.g. Livestock Exclusion areas such as the Blackdown Hills ESA, (Somerset). Buyers and sellers of timber, particularly small lots of special native timber are being brought together under a new Forest Authority Initiative, 'Woodlots'. A new Woodlots area is being developed for Wiltshire and Dorset.

English Nature and partner organisations have developed the Veteran tree Initiative aimed at promoting the importance of very old trees for deadwood, and lichen habitat, as well as their cultural values.

The Brayden Forest Project, (managed by the Wiltshire Wildlife Trust) is working closely with Forest enterprise on restoration of conifer plantations on ancient wood sites e.g. Webbs Wood; other examples of restoration include Harridge Wood (Somerset).

Coppicing and coppice products are promoted through the Wessex Coppice Group, who provide training and advice; the Wildlife Trusts through their practical management on reserves and the marketing of products; and the Royal Forestry Society through their demonstrations and networking.

The Woodland Trust plays a significant role in the region creating new woods on land donated to the Trust. A community Forest for Bristol is an up and running major initiative.

Butterfly Conservation 'New Life to Old woods' campaign aims at promoting the importance and value of veteran trees for dead wood, lichen habitat and cultural value.
