The Scheme comprises the enhancement of the rail infrastructure around Oxford Station, located in the centre of the city of Oxford. The area around the station is highly urbanised, but includes several watercourses, including the Sheepwash Channel, which connects the River Thames east to the Oxford Canal, and over which passes the existing railway north from Oxford Station. Works for the Scheme would involve demolishing and replacing existing buildings, constructing a new railway line and platform, and modifying bridges. Detailed design and delivery of the Scheme is from 2020 to 2024. This report identifies the following ecological features that could constrain the Scheme: • invasive non-native species (INNS); • fish; • reptiles; • birds; • bats; and • otter. Based on the identified constraints, the following further surveys were undertaken: • Survey of invasive non-native plants within 10m of the red line boundary, including land along the railway in a seasonally appropriate time. • Survey for bats at the bridges over the Sheepwash Channel and the seven buildings identified in this report as having potential to support roosting bats. Surveys comprised (reported separately in Appendix 4.3): o hibernation check of the bridges between November and February (inclusive); o internal inspection of buildings, if possible, to identify whether they could be used by roosting bats; and o emergence and re-entry surveys between May and September (inclusive) to determine whether buildings are in use by bats. • Survey of two trees identified as having moderate potential to support roosting bats. Trees were surveyed twice to identify whether they supported bat roosts by an emergence and re-entry survey Page 1 of 172 OFFICIAL Network Rail Oxford Corridor Phase 2 Capacity Improvement Scheme Environmental Impact Assessment – Appendix 4.1: Preliminary Ecological Appraisal Report 163390-JAC-REP-EEN-000002 Revision A04 Avoidance/ Proposed Mitigation Measures: • Best practice to reduce environmental impacts such as by air pollution and contamination of watercourses (e.g. implementation of CIRIA C741). • Development and implementation of an INNS management plan. • Best practice to reduce impacts to fish, otter and bats. The Scheme would: o minimise in-channel works; o time the installation of structure supports either side of the Sheepwash Channel to avoid spawning periods of coarse fish species (March to June); o avoid direct lighting of watercourses, riparian habitat, adjacent woodland and adjacent residential areas; o prevent excessive noise and vibration; and o implement best practice for pollution prevention. • Trees assessed as having low potential to support
