‘Friends’ question councillor’s claims on biodiversity in a solar panel clad country park

…the purpose of the management of the Country Park is to conserve and enhance biodiversity, and the fact that farming methods are used is integral to promoting its biodiversity. The Country Park is not designated ‘Hastings Country Park Nature Reserve’ for nothing, and nature has to come first…

Michael Moor, Chair of The Friends of Hastings Country Park Nature Reserve, has written to Councillor Maya Evans, Hastings Borough Council’s lead member for Climate Change, Biodiversity and Sustainable Development, calling in to question claims she made in recent interviews with Hastings Independent Press and with Hastings In Focus about the council’s plans for the development of a ‘solar farm’ on ten acres of Hastings Country Park.

Here we reproduce his letter to Ms Evans in full.

Solar arrays in Hastings Country Park Nature Reserve

I am writing this open letter on behalf of the Friends of Hastings Country Park Nature Reserve in response to your piece in Hastings Independent Press of October 18th about the council’s proposal to set up about ten acres of solar arrays in the Nature Reserve for which the council has the responsibility of stewardship.

Screenshot 2019-10-31 08.02.43We understand your wish to try to draw some red lines on the project as an implicit attempt to mitigate the inevitable tension between the council’s primary aim of securing income from a solar installation on the one hand and the environmental damage to a sensitive ecosystem on the other. However, we feel that, in the interests of good decision-making by the council, some of the arguments behind those red lines need to be challenged. The matters concerned relate to

  • Biodiversity
  • Concrete foundations and cleaning fluids
  • Farming and the protected landscape.

Hear Maya Evans discuss the environment and Hastings Borough Council’s plans for the country park by clicking the link below 

  1. Biodiversity

Your article suggests that solar panels bring biodiversity as a matter of course. This is frankly a tendentious statement and we would be interested to know on what studies you might be drawing to reach such a conclusion.

As far as we and our advisers are aware, existing independent research only suggests that biodiversity might increase under solar arrays in comparison to fields which are a monoculture in terms of a crop (eg barley). With conventional farming practices, these arable fields will have been managed to reduce biodiversity in terms of wild flowers, invertebrates and crop diseases.

This research cannot be interpreted to mean that biodiversity would increase in the fields immediately above and adjoining the Fairlight Glen SSSI and the field at North’s Seat which are being considered by the council for solar arrays. As permanent pasture these fields are important in terms of carbon sequestration and provide a habitat or food for a range of flora and fauna.

We regard it as disingenuous to try to argue that these fields are already ‘developed’, and are not greenfield sites. It is inevitable that the construction of solar arrays in these fields would result in the disturbance of the soil structure, loss of sequestered carbon, and a loss of biodiversity.

It is also inevitable that solar panels will have a shading effect on the ground beneath them, thus also reducing total photosynthesis, and hence carbon sequestration and biodiversity.

Transformers, Tangmere Solar Farm, West Sussex
Transformers on Tangmere Solar Farm, West Sussex… is this a example of what might need to be installed in Hastings Country Park?

In the initial report to the council’s cabinet in January, an estimate was made of the carbon supposedly saved by installing solar panels. From the council’s studies so far we have not seen any attempt to factor in the carbon cost of making, transporting, installing, managing and eventually decommissioning solar arrays, as well as the continuing reduction in carbon sequestration.

If the council were to make this calculation (as it should) the result would indicate a substantial discount from the initial optimistic guess at carbon saved.

You suggested as one of your red lines that the fields might be managed in part with reseeded wildflowers. However, their creation and management also have environmental implications.

To achieve any substantial biodiversity improvements, the soil across the whole fields would have to be disturbed.

These sites comprise improved pasture, so simply seeding with a wildflower mix without doing anything else is unlikely to be successful. The wildflowers one might want are unlikely to establish well because these fields are nutrient-rich and there would be too much competition. Good soil preparation – with removal of topsoil if nutrient levels are high – is actually regarded as key to re-creation of wildflower meadows, be they real meadows containing only native species of local provenance, or the sort that are called wildflower meadows but where non-local species and non-native species are used.

If wildflower re-seeding with non-local provenance and/or non-native species is what is proposed there may also be issues with doing this close to the SSSI. In addition, the carbon input and loss for establishing and managing wildflower meadows would need to be factored into the council’s estimate for carbon saved from installation of solar arrays (see above).

We are also sceptical about the survival of wildflowers in the face of work required to maintain the panels.

  1. Concrete foundations and cleaning fluids

We are pleased that you are now thinking about your red lines in relation to the foundations for solar panels and cleaning methods but it is optimistic to think that red lines against the use of concrete foundations and chemical cleaning fluids could be sustained in practice.

Concrete is the foundation of choice for contractors installing solar panels because they provide a more stable structure than alternatives. But, of course, the manufacture and transport of concrete comes with a carbon cost. And its installation inevitably causes substantial damage to soil structure and thus to carbon sequestration.

We agree that it is sensible to try to stipulate that no chemical cleaning fluids should be used for any solar arrays, particularly given the risk that they might run off downhill into the SSSI. But anecdotal evidence from other parts of the country indicates that, irrespective of what a cleaning contract might say, contractors resort to such fluids when faced with a difficult cleaning task, for example removing bird faeces from solar panels. With the strong bird population in the trees surrounding the proposed sites and others perching on the panels this could be a significant issue for cleaning solar panels in the Country Park.

It would be difficult to ensure compliance with a contractual condition that would require regular inspection and supervision.

  1. Farming and the protected landscape

In the third paragraph of your article, you say that ‘much of the Country Park is used for farming’. This implies that in those parts of the Nature Reserve where farming does take place biodiversity conservation is secondary. We believe that this sends the wrong message, and is contrary to the council’s management plan for the area. Farming is carried on there in a manner wholly consistent with the overall purpose of the Nature Reserve.

You state that none of the proposed sites comprise protected land. But you fail to mention that they fall within a statutorily protected Local Nature Reserve, within SSSI Impact Risk Zones and an Area of Outstanding Natural Beauty. National planning policy affords AONBs the highest status of protection in relation to conserving and enhancing landscape and scenic beauty. These designations imply a considerable degree of environmental protection.

The High Weald Coast, of which the Country Park is a substantial part, is in the East Sussex Landscape Assessment characterised as a largely unspoilt and tranquil landscape with few intrusive features. This assessment of the landscape beauty are independent and objective, not a matter of perception as you suggested. You also ignore the fact that the solar panels will have to be surrounded by security fencing to ensure public safety and potential damage by intruders and there will be associated cabling and transformers.

In conclusion, the purpose of the management of the Country Park is to conserve and enhance biodiversity, and the fact that farming methods are used is integral to promoting its biodiversity. The Country Park is not designated ‘Hastings Country Park Nature Reserve’ for nothing, and nature has to come first.

  1. Cllr. Evans fails to mention the rigid security required for these ground based solar panels in public areas..These panels carry high voltages and have to be securely fenced off from the public and any large wildlife. The country park is supposed to be open to all for their enjoyment – but if these panels are erected on this special site things will be very different for visitors. There is a load of information on the internet about these large solar panel installationson the ground and it makes for very worrying reading…A vast area of the country park will have to be securely fenced off so no member of the public can get near these panels…I doubt if Maya Evans is aware of much of what goes with these panels…she needs to do some reading on the subject.

  2. My first question concerning Cllr Evans promoting this ten acre Solar panel site in the Country Park is what are her qualifications and experience in such issues? What it appears to me is Cllr Evans has been given this mission to promote green energy issues by her Labour party acting as their official mouthpiece to promote this controversial idea. From what I have read and what Michael Moor is concerned about for this park, it would suggest to me this councillor has no real idea of the implications with what you might call a solar panel farm. Further to put this project in the Country Park.
    In a previous HIF article on this subject there was a very learned and detailed comment by somebody who raised and explained the implications of it being a bad idea. Someone a few councillors should be talking to before promoting what they want and ignoring expert advice and of course us usual members of the public who disagree.

    While I am certainly not against alternative forms of energy and clean ways to produce it, I think in this particular issue Cllr Evans is not sufficiently erudite on this issue. How I see it, someone correct me if I am wrong, this is a Labour party scheme of things where they will insist they are right about this solar panel project. And anyone against it is just plain wrong.
    I can see the Friends of the Country Park are going to have quite a task here to avert this from happening
