The year has started on an alliterative high: food, farming, floods and offsetting.  The latter was the subject of a lively debate at the end of the annual symposium of the Cambridge Conservation Forum.  The Secretary of State's comments at the weekend about offsetting ancient woodland (see here) provided a spicy backdrop.

I took part and tried to explain why the RSPB is, perhaps unfashionably, adopting a "yes, if..." stance.  It is, of course, a hugely complicated subject and is not suited to soundbites and the quality of the debate was good thanks to Tony Gent from Amphibian and Reptile Conservation, Pippa Howard from Fauna and Flora International,  Edward Pollard from The Biodiversity Consultancy and an informed audience.

I started by showing some time-lapse footage of what an offset/compensatory habitat scheme can look (see here).   I wanted to remind people that we do already have a regulated offset system thanks to the Birds and Habitats Directive.  The film showed the breach of the shingle beech that took place on 10 September this year at Medmerry on the Sussex coast.  Regular readers of this blog will know that this is part of a major scheme undertaken by the Environment Agency which we now have the responsibility of managing.  It is first and foremost a flood risk management scheme, but the beauty of it is that it helps create intertidal wildlife habitat to replace internationally important areas being lost through coastal squeeze in the Solent.  

The Environment Agency is obliged under the terms of the Habitats Directive to recreate about 100ha a year to compensate for the loss of protected intertidal habitat.  The Medmerry scheme will make a contribution to address these losses.  

The reason I put a spotlight on Medmerry was that this scheme, and similar ones like it, offer some clues about how to do compensation schemes well and they are instructive in helping government design an offsetting scheme for lower quality habitats - the subject of the Defra consultation that ran late last year.  I have always felt that the mitigation hierarchy written into both international law and domestic policy eg through the National Planning Policy Framework is a good reflection of sustainable development: avoid damage, explore alternative less damaging options, mitigate and then as a last resort compensate for the damage that has been caused by the development.  

The threshold for consenting a project obviously increases with importance of the site – with damage to internationally important sites allowed only if there are overriding reasons of public interest or, in the case of domestic sites, the NPPF needs developers to demonstrate significant benefits to outweigh the costs.

Yet the context for the current consultation is that the natural environment is already under huge pressure.   Historically, we’ve lost a huge extent of habitats 97% of lowland meadow, 80% of lowland Heathland, 94% of lowland raised mires, thousands of square kilometres of wetlands went through drainage.  More recent assessments (through the UKNEA and the State of Nature report) have shown that the decline continue.

With this backdrop we need ensure that any offsetting consultation makes things better rather add to current pressures – that’s what the 2020 biodiversity commitment commits us to.  With real political pressure to kick start the economy and with anti-environment rhetoric you can imagine why the environmental community is nervous.  Yet, even I was surprised to hear that over 20,000 people have signed a petition against offsetting through 38 degrees.  We have lost 388 hectares of anicent woodland over the last ten years with minimal compensation.  While we would never support the destruction of ancient woodland, if the State decides to give damaging development the go ahead, surely it is better to have clear guidance to improve the standards of compensatory habitat schemes?

Let me be clear, the RSPB is not theologically against offsetting – how can we be, given our support of the text in the NPPF and Nature Directives?

Yet, through our own experience, we also know the tests for a successful scheme:

a) respect the mitigation hierarchy. The government has thankfully got this  – we must only trade only trade high quality habitats as a last resort
b) most people think that a clear consistent and mandatory framework is required – that’s what the Defra wants and what the Ecosystem Markets Task Force and the Natural Capital Committee recommend.  It is the clear legal framework that has enabled developers deal with the obligations in the Nature Directives.
c) big schemes like Medmerry can help compensate for lots of little losses – put these schemes in the right place (Nature Improvement Areas, Futurescapes, Living Landscapes etc) and you could potentially help improve connectivity in the countryside.  

Yet, there are also some major bear traps that need to be avoided:

d) Offsetting is not the same as avoiding or mitigating harm.  We must not let the promise of new habitat tomorrow excuse loss of existing habitat today.  This is where I feel that the Secretary of State went too far with his comments on ancient woodland - he gave the impression that it was straightforward and even desirable to let development go ahead and recreate new habitat.  This is wrong.  Our priority must always be to protect existing areas of natural/semi-natural habitat.  Inevitably there is always a lag in the system from creating new habitat of the same functional quality to that which is lost.  We found that when Cardiff Bay Barage was built and compensatory habitat was created along the coast at Newport, the birds failed to find the new habitat and starved.  Equally, different habitats take different amounts of time to create: reedbeds, 35 years, woodlands up to a century, blanket bog about 10,000 years.
e) local authorities will need sufficient capacity/expertise to make the system work – currently only 30% of LPAs have ecologists.  
f) Unlike schemes in US and Australia, our habitats require a little more aftercare/management.  We need the right measures in place to ensure in perpetuity protection and management.  

In conclusion, we’re in the “yes if” camp.  Yes, if...  the government listens to our concerns and designs the best scheme for wildlife in this country. 

  • "In conclusion, we’re in the “yes if” camp.  Yes, if...  the government listens to our concerns and designs the best scheme for wildlife in this country."

    I would substitute the "yes, if" for "no, unless.." If the rspb says yes to this the government will quote you as saying you support their offsetting and mitigation objectives and you will be in great danger of losing credibility in the debate. This is a highly precarious political tightrope you are walking and I agree with Redkite that the rspb proceed with the greatest care on this issue!

  • Martin, when its possible for virtually the whole ecosystem of a reed bed to develop from a carrot field or poplar plantation in just a decade its is certainly not wrong to take a 'yes, if...' approach. What is terrifying - and incompetent beyond belief - is that with valid examples like that the SoS, no doubt advised by his Department, manages to latch onto possibly the very worst (probably alongside heathland) possible example in ancient woodland of a habitat that by its very ecological and heritage definition can't be reproduced. This is a line in the sand. There is a limit to the sheer ignorance that is acceptable from Government which has both the responsibility and resources to inform itself of the very basics of its job  - after basic error after basic error over forestry since it decided to take a hand in policy Defra really should be examining very carefully what is going wrong in the way it discharges its responsibilities.  

  • I think my great concern that relates to "Offsetting" is the way this Government and Mr.Paterson in particular seem to view it as a panacea for removing any wildlife site that maybe in the way of a proposed development. As you point out Martin it maybe possible in some cases to create compensatory habitat but with the wide variety of types of habitat in question and the time that any newly created habitat takes to really achieved wildlife value, (often hundreds of years), true "offsetting" opportunities should be the exception and not the rule if our wildlife is not to suffer steady degradation. If offsetting is managed properly I cannot see it providing the Government with what I think they are looking for,that is quicker and easier solutions for developments. I therefore think that in practice there is potentially a great divergence of view on this subject with conservation organisations.

    Proceed with the greatest of care on this issue would be my advice!!!.
