If bats or signs of bats were found in any of the features, a European Protected Species (EPS) licence for bat development would be necessary to work on or remove the trees.

If roosts are identified, and destruction cannot be avoided, further surveys may be necessary to inform the EPS licensing process.
The Bat Conservation Trust (BCT) Guidelines (BCT, 2007) recommend that when a tree with high potential to support roosting bats is felled, a bat box be erected on a nearby tree. It should be assumed that a tree with high potential to support roosting bats may be used by bats at some point even if no bats have been recorded using it during the surveys. Therefore before any trees which are classified as Category 1, 2 or 3 in terms of their bat roost potential are felled, a Schwegler 1FF bat box is erected on a nearby tree. This would help to compensate for the potential roost lost and help to ensure the potential roost „stock‟ of an area is not decreased as a result of the works. Schwegler 1FF bat boxes are known to be used by a variety of bat species and are also unlikely to be used by nesting birds which can out-compete bats for bat boxes during the nesting bird season.

It is acknowledged that Little Blakenham Pit SSSI which is a known hibernation site for bats is situated approximately 1km to the north west of the Onshore Cable Route and approximately 3km for the Converter Station. There is therefore the potential for lighting impacts on favoured commuting corridors in the proximity to the Onshore Cable Corridor and Converter Station.
122
There would be no 24 hour lighting along the Onshore Cable Route except at HDD locations and all Construction Consolidation Sites. There would however need to be 24 hour lighting at the Converter Station only for key construction activities.
123
Pre-construction activity surveys would be undertaken to identify key commuting routes around the Converter Station. These would follow the same methodology as the baseline surveys undertaken for the ES. This information would then form the basis of a lighting strategy focused on minimising impacts during sensitive construction months. This strategy would be agreed with the local authorities and construction implemented in line with the strategy.
124
The pre construction activity surveys and the pre-construction walkover survey outlined in Section 3.2.1.2 would also be used to inform micro-routing decisions for during-construction mitigation
