Calvert Jubilee by Jim Asher

High Speed Two and Wildlife

We recently received notice from High Speed 2 (HS2) that they intend to carry out clearance works at one of our nature reserves, Calvert Jubilee

The clearance would involve a huge area of land covering approximately 200 hectares, which includes part of Calvert Jubilee nature reserve, a neighbouring Local Wildlife Site, and farmland. We have met with representatives of HS2 to make it clear that the scale and timing of the works will have a devastating effect on wildlife, particularly as it is the start of nesting season. We have also sent a formal letter to HS2 requesting more specific details of the areas to be cleared, how this clearance will take place and the mitigation that will be put in place to compensate for any damage to wildlife. 

We believe that the works will cause unnecessary and unwarranted destruction of important breeding and feeding habitats for a range of species. We therefore strongly object to the proposals as they stand.

If we do not consider that the mitigation proposed by HS2 is adequate we will, to the extent relevant legislation allows us to, refuse access to BBOWT’s land until HS2 produce a scheme of works and mitigation that addresses our concerns and respects the needs of wildlife. 

About HS2

The first phase of the High Speed Two (HS2) railway between London and Birmingham was given Royal Assent on 23 February 2017.

As a result of BBOWT’s strenuous campaign for the impacts of HS2 on wildlife to be reduced, some significant changes to the route have been made, but the HS2 railway line will still have considerable impacts on wildlife along the entire route as well as our nature reserves, Calvert Jubilee and Finemere Wood (more information below).

Since the proposed route was published in 2010, BBOWT has worked hard to reduce the impacts of HS2 on wildlife. BBOWT led the local campaign to speak up for wildlife, called for a Strategic Environmental Assessment of the project and encouraged people to take part in public events.

What is BBOWT doing to improve the future for wildlife and impacts on our nature reserves?

BBOWT continues to push for improvements where we can. The Wildlife Trusts are represented on the Ecology Review Group for HS2, which will examine the impacts of the construction and operation of the line. The Ecology Review Group will also ensure that targets for replacing habitats and dealing with impacts on protected species are actually met.
Phase One of HS2 will have direct impacts on two of our nature reserves: Calvert Jubilee and Finemere Wood. The route of the railway cuts along the eastern side of Calvert Jubilee and the western side of Finemere Wood. The extent of the impact to the meadows at Finemere Wood is not certain yet, as HS2 Ltd has also brought forward proposals to move a railway sidings onto land next to the nature reserve, which will increase the impact even further.

We will keep our web pages for Calvert Jubilee and Finemere Wood up to date with information about contractors working on site, and advise visitors to check these pages before going to the reserves. The impacts on both sites are also likely to be increased as a result of East West Rail (EWR2). The main railway route passes over HS2 at Calvert Jubilee, and the EWR2 spur to Aylesbury runs alongside HS2 at Finemere Wood.

What has BBOWT done to reduce the impact of HS2 on wildlife?

Since 2010 BBOWT has campaigned alongside and in partnership with other organisations, notably HS2 Action Alliance and The Woodland Trust, as well as local groups the Chilterns Conservation Board and the North Bucks Bat Group.

BBOWT produced reports and petitions to the Parliamentary Select Committees, appearing three times before Committees to make the case for better wildlife protection.

As a direct result of our campaigning with The Wildlife Trusts nationally, and with the help of experts Prof John Altringham and Dr Anna Berthinussen from the University of Leeds, we secured:

  • A requirement for a Barn Owl Action Plan to be carried out. Without this Action Plan, phase one of HS2 is expected to kill 1% of the breeding barn owl population in the UK each year.
  • A promise to address shortfalls in the amount of wildlife compensation. We also secured an independent review of the calculations HS2 carried out to monitor their own impact on the natural environment.
  • A commitment for Green Bridges to be built where the line passes through the Bernwood Forest area. These will have 30m wide ‘green’ planting of grass and trees. The HS2 route through Bernwood Forest bisects a colony of Bechstein’s bats, one of the UK’s rarest mammals. BBOWT also secured extensive mitigation proposals for woodland creation in Bernwood Forest.
  • Changes to the Bill to ensure that bats can use the planned underpasses.
  • Alterations to works to ensure parts of our nature reserves are protected, and to ensure visitor access is maintained.

As a result of combined campaigning by BBOWT with HS2 Action Alliance, The Woodland Trust and the Chilterns Conservation Board:

  • Tunnelling was extended under parts of the Chilterns AONB to avoid ancient woodlands that would have been destroyed or bisected by the route.
  • The Government changed the way that information on environmental impacts is presented to MPs before they vote on large projects.
  • The European Commission confirmed that they “remain of the view that large transport infrastructure developments such as this should be addressed….through the process foreseen in the SEA Directive”. We supported a legal challenge, asking the UK Supreme Court to rule that a Strategic Environmental Assessment (SEA) should have been carried out.
  • The Government eventually carried out a review of the possible impacts of HS2 on the South West London Waterbodies, a Special Protection Area for wildlife, just before the failure to carry out the review was addressed in the High Court.
  • HS2 Ltd removed ancient woodland impacts from their calculation of “no net loss” to biodiversity. Having Ancient Woodland in the calculations for a scheme approved by Parliament would have given the green light to other developers that they could damage irreplaceable habitats and still claim they were producing “no net loss” of impact.
  • An additional £5million has been provided by HS2 Ltd for tree planting along the route.
