Recognise the importance and value of the historic hedgerow pattern and replace where it has been lost to enhance the landscape character and strengthen connectivity of habitats. Encourage the establishment of new hedgerow trees. Maintain and improve the condition of existing hedgerows through traditional cutting regimes

Recognise the importance of new woodland planting to minimise the impact of new infrastructure and manage using traditional techniques to create and manage a wide diversity of habitats.

Recognise the importance of neutral grassland

Recognise the importance of the character of minor roads by the planting and management of hedgerows and verges and limiting urbanising elements such as signs and kerbs.

Recognise the importance and value of the existing historic hedgerow pattern and plant up with new hedgerow trees. Seek to restore the historic hedgerow pattern where it has been lost to enhance the landscape character and strengthen the ecological diversity and implement management through traditional cutting regimes.

Recognise the importance of woodland and through planting and management using traditional techniques create and manage a wide diversity of habitats.

Recognise the importance of historic meadows and unimproved and semi-improved grassland close to watercourses and promote the use of permanent pasture, with low stocking density and flooding regimes to promote biodiversity and landscape enhancement.

1MC07-CEK-IN-PRE-CS07_CL13-000001 5. Driving the Vision

• Turweston, • Westbury, • Mixbury, • Finmere & Evenley

Through successful design and delivery of enhancement measures, such as creating new public access, opportunities for education, art and interpretation of the landscape, biodiversity and heritage, handing back land for farming, or managing land for economic return such as woodland for fuel or opportunities for grassed areas to be opened up to grazing rights

Characteristic regional hedges Any part of Britain which possesses hedges can be identified by them. Clues may be given by the way in which they are managed, the type of associated bank or ditch, the hedge plants, or the way in which the climate has influenced growth.

1MC07-CEK-IN-PRE-CS07_CL13-000001 Information Paper E20

Control of Airborne Noise

• The nominated undertaker will take all reasonable steps to design and construct altered roads, and to design, construct, operate and maintain the operational railway so that the combined airborne noise from these sources, predicted in all reasonably foreseeable circumstances, does not exceed the lowest observed adverse effect levels (LOAEL)

• Where it is not reasonably practicable to achieve this objective, the nominated undertaker will reduce airborne noise from the altered roads and the operational railway as far as is reasonably practicable

• Noise insulation will be offered with the aim that airborne noise from altered roads and the operational railway does not give rise to significant adverse effects on health and quality of life that would otherwise be expected when airborne noise exceeds the significant observed adverse effect levels (SOAEL)
