Calls to stop HS2 tree felling over worries for bats
HS2 argue they've found no evidence of roosts
More trees are being cut down for HS2 near Great Missenden and there are worries bats won't be protected.
Despite promises of provision for a bat corridor on Leather Lane by HS2 contractors, campaigners say felling starting today leaves those in doubt.
HS2 told us they're only felling the trees directly in the line's path.
HS2 Rebellion are currently in dialogue with EKFB and have employed a civil engineer to design a viable alternative route for the over-road and bat corridor.
What are the worries?
The group say that it is the height of summer when bats and endless other wildlife are active and using the trees and ecosystem along Leather Lane for habitat, foraging, and commuting.
Felling at this time not only goes against the Precautionary Principle adopted by HS2 in their Environmental Statement, but it is also in contravention of their Local Environmental Management plans and all good practice regarding wildlife protection, prevention, and mitigation.
Leather Lane is an ancient, sunken lane, known as a Holloway. It is lined to the south with 99 oak trees. It was originally planted by Arthur Lazenby Liberty in the late 1800s, and is set within the Central Chilterns Area of Outstanding Natural Beauty (AONB).
Campaigners say this 'irreplaceable' bat corridor is 'under immediate threat' as HS2 are currently planning the overbridge on the southern side, putting endless oak trees and the ecosystem at imminent risk.
This will fragment the corridor and will impact the bats' ability to forage and travel between other habitats, threatening bat populations and putting the conservation status of the endangered Barbastelle bat under threat, they say.
HS2 Rebellion say:
"HS2 and EKFB have failed to uphold their legal obligations and their own standards and commitments to ecology and biodiversity, and no mitigation has been put in place.
"As a result, we stand to lose this irreplaceable holloway and bat corridor, which will have a huge impact on the Chilterns landscape, biodiversity, and bat species at both a local level and national level.
"With the government's recent G7 re-commitment to halt biodiversity loss, this issue is especially poignant at this critical time for the environment."
In the absence of surveys from HS2, concerned local residents have stepped in to commission several independent bat surveys, which show that there are at least seven species of bat - including the endangered Barbastelle bat - which are continually using this vital corridor in high numbers.
Furthermore, the current designs are for a standard two-way road, which does not take into account the design principles submitted to protect the AONB,1 and will require more land and earthworks.
Local residents, with the support of bat experts, ecologists, engineers and lawyers, are campaigning to reduce the overbridge to a one-way road on the northern side and to provide mitigation for the bats to get over the tracks. This will have the effect of saving lives and reconnecting the fragmented landscape, as otherwise the current works will lead to population decline if not addressed immediately.
Expert John Altringham, Emeritus Professor of Ecology and Conservation at the University of Leeds, who advises national authorities including Natural England and the Bat Conservation Trust on bat ecology and conservation issues, has confirmed that.
He said:
"As few trees as possible should be removed to retain foraging habitat, roost potential and connectivity across this fragmented landscape.
"All species are under considerable pressure and their small populations reflect the already degraded nature of the landscape. Further stress on species through habitat degradation, loss and fragmentation will inevitably lead to further decline and possibly local extinction."
Barbastelle bats are among other bat species that have been detected using the bat corridor. They have recently lost roosts at nearby Jones Hill Wood following felling of trees containing known roosts, and as a result their species is under threat. The Barbastelle bat is afforded protection under the Habitats directive.
Professor Altringham added:
"The Annex II Barbastelle already has a thin and patchy distribution in the UK, so local loss of this species is of national importance, in part because it leads to ever more isolated local populations, which become increasingly vulnerable to the effects of climate change and other pressures."
The campaigners are demanding that EKFB:
- Suspend felling until bridge design is agreed and bats go into hibernation;
- Sincerely consider the design to route the overbridge to the Northern side;
- Adopt the design principles submitted by the Chilterns AONB group to design a one-way lane, in keeping with the holloway and Chilterns AONB, and keep the track within the Act limits; and
- Create a bat corridor over the track cutting to prevent unnecessary deaths and protect their conservation status.
They demand that HS2 lives up to its PR on green bridges and upholds its commitments to net loss and protection of biodiversity, as required by law.
An HS2 spokesperson said:
“HS2 always strives to reduce our impact on the environment, however some trees on Leather Lane are directly in the line of where the new railway will be built.
"We have the necessary bat licence from Natural England, however there is no evidence of bat roosts in the affected trees and measures will be put in place to create a temporary bat flight path during our works.
“The construction of HS2 is playing a vital role in Britain’s economic recovery from Covid-19, with over 16,000 people already working on the project, both directly and across our UK-wide supply chain.
"By providing a cleaner, greener way to travel, HS2 will help cut the number of cars and lorries on our roads, cut demand for domestic flights, and help the country’s push to reduce carbon emissions.”
