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. Landscape Information - Clay Vale of Buckingham Twyford Vale Recognise the importance of the historic hedgerow pattern by infilling gaps and establishing new hedgerow trees and encourage the management of hedgerows through traditional cutting regimes. Recognise the importance and promote the management and conservation of vegetation adjacent to the meandering watercourses including the pollarding of willows and promote connectivity of habitats. Recognise the importance of the historic meadows and unimproved and semi-improved grassland. Seek opportunities to promote the use of permanent pasture, with low stocking density and flooding regimes to promote biodiversity and landscape enhancement. Landscape Planting - Cutting Landscape Planting

Increased biodiversity in landscape planting. Focus on native species planting and adapting planting plans for local areas (use local material, collecting seeds).

Climate change resilience and futureproofing – species could use green corridors to adapt to changes in climate. Landscape Planting - Landforms Landscape Context Preston Bissett - Plateau Edge LCA Undulating clay plateau incised by a number of small streams which drain into the Brook. Several small woodlands which create a relatively well-wooded character (particularly between Chetwode and . A strong pattern of hedgerows with numerous mature trees. The land use comprises mixed farming (predominantly arable).

Train Types and Service Pattern

Classic Compatible • Runs on conventional lines (ECML / WCML) and HS2 • Standard rail gauge • Less aerodynamic shielding • Louder Captive • Runs of HS2 line only • Greater gauge clearance • More aerodynamic shielding • Quieter Track Types

ES based ballasted track Current proposals based on slab track Noise Mitigation Traffic Access Routes

1: As part of the enabling works, Fusion will be upgrading junctions at the M40 Junction 10 and on the A43 to allow for the increase in traffic. 2: Construction Vehicles will not be able to access at this point. We will be using our Internal Access Road to access all sites within the area south of the A4421. 3: The A43 compound will be a primary point of access heading north to the C3 section of the route. It will also be used as a primary access heading south once the overbridge has been completed.
