  • New fracking licences cover SSSIs and RSPB reserves

    Government has today offered new licences for onshore oil and gas, many of which are expected to result in exploration for and production of oil and gas using fracking.

    27 licences have been offered, with a further 132 that have been assessed for their environmental impact announced and opened up to consultation.

    Government's claim is that the 132 licences that remain up for consultation are the environmentally sensitive licences. They rightly identify potential impacts on sites such as Special Areas of Conservation and Special Protection Areas that are important for wildlife at a European level and designated as such.

    But in the 27 licences that are going ahead without this extra scrutiny, there are 53 Sites of Special Scientific Interest and three RSPB reserves. This is clearly the first manifestation of Government dropping a promise to ban fracking in SSSIs.

    RSPB Fairburn Ings, Dearne Valley and Langford Lowfield are all included in the 27 new licences. I visited Fairburn Ings a few years ago and it's a beautiful reserve on the site of a former coal mine, but we definitely don't want to see fossil fuel extraction return here. It's now the site of a huge lake and beautiful woodlands that are home to woodpeckers, swans and kingfishers. Fracking at these 53 SSSIs or RSPB reserves could put birds like godwits, goldeneyes and bitterns at risk.

    Amber Rudd, now Secretary of State for Climate Change, made the to rule out SSSIs promise back in February, but dropped SSSIs from the list of Protected Areas when it issued new secondary legislation in June. It still promises to rule out fracking in National Parks, Areas of Outstanding Natural Beauty and World Heritage Sites, but hasn't done so yet.

    Government should attach conditions to fracking licences banning surface activity in all Protected Areas including SSSIs.

    But, protecting our most important wildlife sites wouldn't be the end of the chapter on fracking. We still don't think the regulatory regime for fracking is fit for purpose, and we're yet to see a compelling case that fracking is compatible with our climate change targets (we await a report the Committee on Climate Change must make to Government on this issue by 2016).

    Government appears to be rushing ahead with fracking, putting some of our most precious and sensitive wildlife at risk. Instead, their priority should be ensuring long-term support and certainty for the low-carbon and renewable industry that can help to drive down our climate change emissions.

    We will be looking very closely at the detail of the 132 licences, sharing more analysis, and responding to Government's consultation in the coming days.

  • Government issues new planning guidance on fracking

    Summer is normally considered a fairly quiet period politically, but on the fracking front things are hotting up.

    Today Government made the latest in a string of announcements, the most important part of which was to issue a plea for local authorities to process planning applications for fracking more quickly, given the important national need for our energy security and economy to kickstart the fracking industry.

    The Secretary of State for Communities and Local Government threatens to decide applications himself where they are taking too long.

    Seeking a more efficient planning system mustn't be at the expense of the quality of the decisions made. There's no point putting undue pressure on local authorities to hurry decisions about an unconventional technology and fossil fuel resource.

    Instead, Government should be promoting a more cautious and careful approach than normal that offers the utmost protection for people and the environment. No one, Government, industry, communities or NGOs want to see the wrong decisions made about where fracking should be allowed.

    Today's announcement came against the backdrop of a worrying approach to fracking from Government - only a few weeks ago they dropped a promise to ban fracking in Sites of Special Scientific Interest, and delayed fulfilling a promise to ban it in National Parks and Areas of Outstanding Natural Beauty.

    We're not convinced that the regulations around fracking are fit for purpose, and Government's priority should be getting those in order and ruling out our most important wildlife sites, before rushing ahead with rolling out permission to frack (Government plans to announce new fracking licences this Summer).

    What's more, we still haven't seen compelling evidence that fracking is compatible with the UK's carbon budgets (we eagerly await the Committee on Climate Change's report on this by April 2016).

    The Committee on Climate Change made it clear that fracking could only be compatible with our near term carbon budgets if other sectors of the economy made cuts in emissions. If the Government is to push ahead with fracking this makes it more important than ever that Government explain how they will guarantee a secure future for the low carbon industry, particularly given closures and cuts for schemes and subsidies in recent weeks.

    RSPB is asking Government to:

    - rule out fracking in all protected areas, including SSSIs 
    - address a number of other weaknesses in the regulation around fracking
    - demonstrate that fracking is compatible with our climate change commitments 
    - provide long-term security for the low-carbon sector beyond 2020

  • Climate change could threaten blanket bogs, craneflies and breeding birds

    Guest blog by Dr Matthew Carroll, Conservation Scientist at RSPB Centre for Conservation Science

    Craneflies as a food source for upland breeding birds

    The British uplands are home to internationally-important breeding bird populations. And for some of these species, a key part of their diet during the breeding season is something you might not have expected – craneflies, or daddy longlegs as they’re often better known. For birds that breed on blanket bogs – deep peat soils that occur on rolling hills in the wettest areas of the uplands – craneflies can make up a big part of the diet during this critical period.

    Both chicks and adults can rely on cranefly larvae and adults for food during the breeding season. For species like golden plover and red grouse, it’s been shown that chick growth and survival rates are higher when there are more craneflies available. So these unassuming flies are a very important part of the food chain. But research we’ve just published in Nature Communications suggests that climate change might threaten the whole food web.

    Craneflies need wet peat to survive and thrive

    The key link in the chain is soil moisture. Cranefly larvae live in the top few centimetres of peat, and they die when the peat becomes too dry. Some of our previous research published in Global Change Biology, Maintaining northern peatland ecosystems in a changing climate: effects of soil moisture, drainage and drain blocking on craneflies has shown that higher cranefly abundances are associated with wetter peat, so things like inappropriate drainage can cause their populations to fall.

    Climate warming could make peat too dry

    But it’s not just drainage that could make the peat become drier. Climate change could lead to warmer, drier summers, and this could threaten cranefly populations even on bogs that have never been drained. So our work examines this system, to see what the impacts of climate change might be.

    We used a model that predicts how wet peat bogs are, based on weather (temperature and rainfall) and landscape characteristics (altitude, steepness of slopes). We then combined these predicted water-table depths with observations of cranefly abundance so that, for a given set of weather and landscape conditions, we could estimate cranefly abundances. And then we used our cranefly predictions to see how bird populations responded to varying food supplies, and how things might change in the future.

    First, we looked at the Peak District, where big bird surveys were carried out in 1990 by English Nature and 2004 by Moors for the Future Partnership. We found that where our model predicted the highest cranefly abundances to be, the largest breeding bird populations had been seen. This pattern was found for three iconic upland species that eat craneflies during the breeding season – golden plover, dunlin and red grouse. So, where there was more food, there were more birds!

    Cranefly declines = golden plover and dunlin declines

    Then, we used climate change projections to see what might happen in the future. We found that as summer temperatures rise and rainfall decreases, blanket bogs are indeed predicted to become drier. This would mean that cranefly populations could fall by up to 80% by the late 21st Century. In some places, high cranefly abundances would be restricted to the wettest bits of the landscape. Relatively dry areas like the North York Moors may end up with very few craneflies left at all.

    And what would these declines in cranefly abundance mean for the birds? Well in the Peak District, we could see big abundance declines. Dunlin abundance was projected to decline by about 50%, whilst golden plover abundance was projected to decline by nearly 30% - these are clearly big losses. By the late 21st Century, both dunlin and golden plover might only be found in the wettest areas that still retain enough food for them.

    Conservation action for craneflies

    So, it might seem a bit bleak – our model suggests that climate change could threaten some of our important upland bird populations. But there is hope. Our previous research has shown that blocking  drainage ditches, which increases soil moisture levels, can increase cranefly populations. Drain blocking, along with re-vegetating bare peat, are key parts of blanket bog restoration and conservation strategies that the RSPB are involved with, in places such as Dove Stone in the Peak District and Lake Vyrnwy in mid Wales. These actions should help to keep bogs wet and provide a better future for the whole ecosystem as the climate changes. Knowing how climate affects hydrology, how hydrology affects invertebrates, and how prey availability affects birds, we can start to identify conservation actions. To maintain our upland bird populations in the face of a changing climate, we  need to ensure that blanket bogs stay wet and craneflies remain abundant.
