It describes the typical threats and influences and the opportunities that may exist for positive action. Links are made to sources of further information and guidance. New Planting Parking and Picnic Areas Boundaries and Linear Features Boundary and linear features have been identified as priority habitats by the UK Biodiversity Steering Group. Road networks create very long boundaries indeed. Dykes provide an important habitat for lichens, mosses, ferns and flowering plants.
Small holes can form nesting sites for birds such as wrens, wheatear and wagtails.
Reptiles such as adders and lizards may hunt and hide in crevices. Even old remnant walls can be good habitats for plants and insects. Hedges and dykes may have ditches associated with them, and this increases the species diversity of the habitat. Existing hedgerows should be protected and enhanced by implementing good management practices, and new hedges should be planted using appropriate species mixes for the locality. Construction of new drystone walling, perhaps using surplus excavated materials from road works, should also be considered.
