Sussex Wildlife Trust / University of Sussex 50th Anniversary conference: The Nature of Change.

On 15th September this year the SWT joined with the University of Sussex for a major conference. We called this “The Nature of Change” because, as well as being our 50th anniversaries, this could be a major period of change for the natural environment.

Our conference was opened by Professor Michael Farthing, the Vice Chancellor of the University and then we gained a fascinating insight into the last 100 years of nature conservation in Sussex. David Streeter, founder member and President of the SWT, traced the history of 8 very special places in Sussex first identified by Charles Rothschild (the founder of the Society for the Promotion of Nature Reserves) in 1912. Looking at the detail of what has happened to places like Amberley Wildbrooks gives a good illustration of how nature conservation has grown in extent and influence over the last 100 years.

The theme of the conference then moved on to the major issues that should have a major influence on our relationship with the natural world in the future. Although they are not new ideas, concepts like landscape ecology, ecological restoration and ecosystem services have been developing considerably in recent years. We therefore received a series of four excellent presentations on these subjects:

• 
  First was a talk on the “Making space for nature” review into the functioning of England’s ecological network. A major document, highly influential to government, which outlined the failings of England’s ecological network and gave a series of recommendations for improvement.




• 
  Then there were two presentations on the National Ecosystem Assessment, giving an outline on how ecosystem assessment works and some of the key messages to come out of the NEA.




• 
  The last morning session was from DEFRA, talking about the England Biodiversity Strategy and how this is taking on the messages form the making space for nature review and the NEA.

The afternoon sessions presented a challenge to some major organisations in Sussex – how will they respond to this call for a much higher ambition for the natural world?

In the afternoon we therefore had presentations from:

• Natural England,




• the Environment Agency




• the South Downs National Park Authority and




• East Sussex County Council,

all giving a great insight into what this greater ambition might mean in practical terms.

It was a good conference, and I am very grateful to all the speakers involved. All the presentations can be viewed on the following link:

Of all the thousands of pages that have been written in the National Ecosystem Assessment it is perhaps the first sentence that is most important:

“The natural world, its biodiversity and its constituent ecosystems are critically important to our well-being and economic prosperity, but are consistently undervalued in conventional economic analyses and decision making.”

Our 50th anniversary is a good time to move from this to a situation where we value, restore, recreate and reconnect nature, for its own inherent value and so it can provide the services on which we all depend.

The Launch of the National Ecosystem Assessment

At its launch, Oliver Letwin (Minister for Government Policy) said that the National Ecosystem Assessment was one of the most important things government has done for a very long time. He referred to it being “paradigm changing” and said that it shows that we can’t just ignore the value of nature, indeed it must now become central in all decision making.

I tend to agree with him. The National Ecosystem Assessment should create a major change in the way nature is valued. This is internationally leading, ground breaking stuff which should help re-write the rules on how our society can live sustainably with the natural resources on which it depends. And yet, although it has been reported to some extent, the importance of this work seems to have escaped most in the media.

The first “Key Message” in the introduction is perhaps the most important paragraph in the whole document so I will repeat it verbatim:

"The natural world, its biodiversity and its constituent ecosystems are critically important to our well-being and economic prosperity, but are consistently undervalued in conventional economic analysis and decision making. Ecosystems and the services they deliver underpin our very existence. We depend on them to produce our food, regulate water supplies and climate, and breakdown waste products. We also value them in less obvious ways: contact with nature gives pleasure, provides recreation and is known to have a positive impact on long-term health and happiness."

So that sets the context. Yet most of our ecosystem services are degrading or existing in an already degraded state. (For example about 50% of the marine fisheries are being managed sustainably – but fish stocks are being sustained at a level about 10 times lower than they were 100 years ago). If you are one of those people who can only think in economic terms then we are loosing economic benefit because we have degraded our ecosystems. And future trends are likely to degrade these ecosystems still further. Its more important than life or death – this is costing us money!

Add this to the findings of the review by John Lawton ”Making Space for Nature” and you come to the conclusion that England does not have a functional ecological network and the ecosystem services on which we all depend are in long term decline.

Of course this is nothing new; we have known this for decades, but this in an internationally leading study which should feed straight in to government policy. Government should be listening and going by Oliver Letwin’s comments, they are. Indeed Prof Bob Watson (DEFRA Chief Scientist) said that he has never seen a document have such a rapid effect on government policy.

Indeed environmental policy has been breaking records recently:

• there never has been a review like Lawton’s “Making space for nature” before,


• there never has been such a public response to any government policy as there was to the consultation on the Natural Environment White Paper (15,000 responses) and


• the NEA has possibly had one of the most rapid effects on government policy of any document.

I have been critical in a past blog of the coalition government seeming to get off track with its environmental record. Well maybe this can change matters. The Natural Environment White Paper is due out on 7th June. This clearly must set the right trajectory by picking up the recommendations in the Lawton review and by responding to the key messages in the NEA. But it is what happens next that is important. How will any policy changes in this White Paper be reflected in practical results at local, national and international level?

A future for the Public Forest Estate

The problem with the current debate about the public forest estate is that it started in the wrong place. Admittedly it did attract a great deal of public interest, but instead of asking

“how can we dispose of the estate?”

it should have started with the question

“what is the purpose of the estate?”.

This question has been asked and answered many times over, most recently in a report done in 2009. http://www.forestry.gov.uk/forestry/infd-7rufme

Not long ago perhaps, but a lot is changing. The “Lawton review” has made strong recommendations about how to develop a coherent ecological network and the National Ecosystem Assessment has looked at how we can better value the benefits we get from nature. Both of these are key drivers in the forthcoming Natural Environment White Paper. Any future for the public estate must fit within the concept of restoring the natural environment that flows from these documents.

If you want to read some of my thoughts on these please take a look at my blog posts around September last year starting at:

http://tonywhitbread.blogspot.com/2010/08/natural-environment-white-paper-2.html.

Against this background, perhaps it is relevant to ask the question again. If we did then I suggest that the purpose of the estate should go along the following lines:

• The purpose of the public estate is to contribute to realising the full potential of England’s current and future ecological network, so that it provides the ecosystem services on which we depend.

(If you don’t know what I mean by ecosystem services then again please look back to my blogs in 2010)

In practice this is perhaps just a current way of describing multi-purpose forestry, which FC tries to do anyway. But it is perhaps a better recognition that forests deliver a lot more than just timber.

The problem is that this could be the policy objective for all forest management (indeed all land management) – public and private. So the public forest estate must have a special role, something complementary to the private sector.

In my mind this specialness is that the public estate should deliver ecosystem services that are not easily valued in traditional economic terms and so not easily delivered by the private sector.

We can work out the price of timber, but it is harder to value soil formation, nutrient cycling, wild species, climate amelioration or ecological interactions. Other services we get include recreation, access, spiritual enrichment, wildlife and the appreciation of wildlife. We know these are essential, but we hope nature provides them for free. These ecosystem services are our public benefits and do have a value (when the sums are done the value can be 100 times more than the cost of conservation) and the public estate should be there to deliver them as its primary role.

Outside the public estate, management approaches that support these services might be seen as a “cost” to be supported by providing “grants”. A public forest estate, however, should support these as its normal way of operating. So, as well as producing timber, the estate should use (and demonstrate) management approaches that also deliver all other services. It would therefore be an exemplar of multi-purpose land management. One consequence will be that, as so many other benefits are recognised, there will be significant areas of land where other ecosystem services are emphasised and timber production will be far less of an objective.

In order to do this the public forest estate will need to be large and diverse, covering the range of ecological conditions and management situations found in England. It will also need to be transparent and accountable. It will need to be in the places where it can best deliver aspects of public benefit that are less easily delivered by private and charitable sectors. This could mean re-configuring the current public estate, maybe selling some areas but purchasing others. In order to achieve its purpose, it is likely that the net size (i.e. after selling some areas and acquiring others) will be larger than it is at present, not smaller.

This is perhaps my long-winded way of supporting the position statement articulated by the Save Our Woods campaign
http://saveourwoods.co.uk/news/sow-briefing-for-westminster-debate-on-the-future-of-the-fc/

What’s more this seems to be what everybody wants – a bigger, more effective public estate.

Maybe this will be difficult to achieve in the current economic climate but plans for a public estate should be long term. At least we should hold on to a good thing while we’ve got it. A more expansive agenda could then follow when conditions permit.

The Natural Environment White Paper 5

The third of the main drivers behind the forthcoming White Paper is the “Making Space for Nature: a review of England’s Wildlife Sites and Ecological Network”, chaired by Professor Sir John Lawton. This was published last week and, after getting a sneak preview of earlier drafts it is interesting to see how this has turned out.

You can look at the whole document, or the summary on the defra website (under "making space for nature") at:

http://www.defra.gov.uk/environment/biodiversity/index.htm

I would thoroughly recommend that you at least look through the summary. You can then draw your own conclusions on the scale of the changes that might be needed to address its conclusions.

In my mind this review should be absolutely fundamental. I’ve talked about ecosystem services and so far much of the discussion is at an international scale (with The Economics of Ecosystems and Biodiversity) or national scale (with the National Ecosystem Assessment). These are good but it will all only start to mean something when we get down to how areas/places that we know are actually doing as functioning ecosystems – “do England’s wildlife sites comprise a coherent and resilient ecological network”.

Basically the review asks whether our current approach is going to deliver an environment that conserves healthy, functioning ecosystems that maintain biodiversity and provide us with all the ecosystem services that we need. If we look out of the window, will what we see deliver what we need. Unsurprisingly the answer is “no”.

The review gives the aim of an ecological network as one where:
“compared to 2000, biodiversity is enhanced and the diversity, functioning and resilience of ecosystems re-established in a network of spaces for nature that can sustain these levels into the future, even given continuing environmental change and human pressure.”

Underpinning this are three objectives:

• 
  To restore species and habitats to levels better than in 2000 and that are sustainable in a changing climate.
• 
  To restore the ecological and physical processes that underpin ecosystems, thereby enhancing the capacity to provide ecosystem services.
• 
  To provide accessible, wildlife rich, natural environments for people to enjoy and experience

The review then looked at the current situation to see whether our existing approach works. To do this it tested against 5 attributes:

1. 
   Does the network support the full range of biodiversity?
2. 
   Is the network of adequate size?
3. 
   Do the network sites receive long-term protection and appropriate management?
4. 
   Are there sufficient ecological connections to enable species movement?
5. 
   Are sites valued by and accessible to people?

The review essentially concluded that our current scatter of wildlife sites does not comprise a coherent and resilient ecological network. Indeed of the 5 tests above it is only the first that is substantially met. I know any one of us could have told government this but it is highly significant that a government commission, drawing on a wide range of evidence and expert opinion came to this inevitable conclusion.

From my brief overview, I would say that this is a good review. It says a lot that we have been saying as part of our Living Landscape approach. It also seems to come to similar conclusions about what is needed to reverse the situation and deliver a coherent ecological network. More of that in future blog posts.
