HS2 now required to declare construction impact on woodlands and local roads HS2 Ltd will be required to publish reports on the scheme’s impact on ancient woodland, as well as giving local authorities more notice about road closures. The new measures are part of amendments made to the West Midlands to Crewe (Phase 2a) bill. The amendments tabled by the House of Lords have now been passed by MPs. They require HS2 Ltd to publish annual reports regarding the construction impact of each phase of the scheme on ancient woodland. High Speed 2 (HS2) minister Andrew Stephenson said he has also committed to “wider environmental reporting” on the scheme’s impact.
