A public consultation on the plans for a Lower Thames Crossing east of Gravesend is now open, and runs until the 20th December 2018. www.lowerthamescrossing.co.uk/haveyoursay
In 2017 the Department for Transport announced that the route the ‘Lower Thames Crossing’ will take in Kent will be a bored tunnel east of Gravesend, and the 'Western Southern Link Road' to link this with the A2. Kent Wildlife Trust remains opposed to a crossing at this location (‘Option C’).
The Trust remains opposed to a crossing at 'Location C', but recognises that a bored tunnel reduces impacts upon the internationally important habitats of the North Kent Marshes and Thames Estuary compared to the other crossing types.
We also recognise that the chosen 'Western Southern Link Road' will result in the loss of a smaller area of important wildlife habitats compared to the previously-suggested preference, the 'Eastern Southern Link Road'.
Either link road option would have resulted in the loss of ancient woodland, but specifically, the Western Southern Link Road (the chosen route) has the potential to destroy parts of Shorne & Ashenbank Woods SSSI and Claylane Woods.
Owing to the potential for the route to destroy woodland and farmland habitats and associated species, we will be expecting that these impacts are properly identified, and avoided and minimised wherever possible.
Not only will we also be looking for adequate mitigation and compensation for any impacts, we will also be seeking 'enhancements' to the local environment and habitat connectivity.
Ancient Woodland is an irreplaceable habitat, so we will be expecting at least 30 hectares of woodland to be planted (excluding verges and embankments) for every hectare of ancient woodland lost.
We still believe that the decision-making process is flawed.
While the economic benefits have been weighed against the financial costs, they have not assessed the economic costs, for example, the impact on community health, ecosystem services, or tourism. Kent Wildlife Trust believes that the only sustainable way to reduce congestion is to reduce demand. This has the additional benefit of reducing air pollution and the greenhouse gasses that result in climate change. Air pollution is the leading environmental health risk factor in the UK, and climate change is one of the greatest threats to our environment and the ‘ecosystem services’ which we depend upon.
We believe that road developments should only be considered as a last resort within a sustainable transport strategy, which must be planned and fully integrated with conservation objectives and the land use planning process. This should:
- prioritise environmentally sensitive maintenance and improvement of the current road network over new road schemes
- reduce the need to travel, for example through: well-designed towns, cities and neighbourhoods; and improved transport technology
- promote reductions in private vehicle use in order to reduce traffic levels, fuel consumption and vehicle emissions, including fiscal measures and car share schemes
- minimise dependency on private vehicle use by increasing and improving public transport and active travel routes, which are well connected to essential services
A public consultation on the Lower Thames Crossing proposals ran from the 26th January to the 24th March 2016. Kent Wildlife Trust's full response to the consultation can be downloaded below, but in summary, we have called upon Highways England to:
- Undertake a proper analysis of the economic case for a Lower Thames Crossing that takes into account wider economic impacts, including environmental economic impacts
- Demonstrate that alternatives to further unsustainable road construction are not a better fit to the stated objectives of the scheme, given due regard to those objectives
- Reject the Eastern Southern Link Road, owing to an unacceptable environmental impact
- Reconsider the Western Southern Link Road, with the aim to avoid environmental impacts
- If Option C is chosen, rule out all crossing types apart from a bored tunnel
- Undertake a full analysis of the direct and indirect impacts of any chosen scheme, with an aim to have regard to the avoid-mitigate-compensate hierarchy, ensuring any mitigation or compensation is properly planned within a strategic ecological network, managed in perpetuity, and properly funded.
About the Sites
A site of Special Scientific Interest (SSSI) is a national designation intended to provide statutory protection for the best examples of the UK's flora, fauna, or geological features. Local Wildlife Site (LWS) is a non-statutory designation and provides no legal protection (though species supported by LWS may have legal protection). It is given to sites that are important for wildlife at a county level and above. More information on Kent’s Local Wildlife Sites can be found here. An ancient woodland is one which has been present since 1600, and are often best identified by the suite of ‘indicator species’ that they support. Ancient woodlands now only cover about 2% of the country and are irreplaceable.
Shorne and Ashenbank Woods SSSI
Shorne and Ashenbank Woods SSSI include both Shorne Woods Country Park and the Woodland Trust’s Ashenbank Woods on the other side of the A2. Part of the former may be lost to the widening of the A2 should the western link road be built.
The site supports an important and diverse invertebrate fauna, especially beetles, true bugs and dragonflies. The woodland varies from sweet chestnut coppice to a more mixed broadleaved woodland of mature oak, sweet chestnut, and hornbeam, and holly and yew are frequent in the understorey. Bramble, bluebell, dog’s mercury, and bracken dominate the ground flora, together with ancient woodland indicators such as wood spurge, wood sedge and wood anemone. The woodland breeding bird community includes hawfinch, marsh tit and all three British woodpeckers.
Like Great Crabbles, Shorne and Court Woods, Claylane Wood is ancient woodland. We do not have much information on this woodland.
