London Resort, Swanscombe, the BBC and biodiversity… actions will speak louder than words

Are you enjoying Green Planet, the BBC’s latest natural-history blockbuster (showing now on all working televisions)?
Of course, the corporation’s standards in this field are second to none, while it makes a big deal of its record on sustainability, so it’s difficult to understand its involvement in the proposed development of the London Resort theme park, a scheme that would effectively destroy one of the most wildlife-rich sites in the country – the Swanscombe peninsula.
Campaigner Chris Rose highlights this apparent quandary in his blog on biodiversity, which will be highlighted during COP CBD15, or the 15th Conference of the Parties of the Convention on Biological Diversity, taking place in China in May.
As he points out, the ongoing loss of biodiversity – the ‘nature emergency’ – is overshadowed by the climate emergency, even though the two are inextricably linked. This, he argues, needs to change, with lip-service to the cause of biodiversity translating into genuine action and policy change.
The failure of the theme-park developer, London Resort Company Holdings, to meet deadlines has delayed the Planning Inspectorate’s six-month examination of its application and the process is now anticipated to begin in March (it had been scheduled for September last year), meaning it is likely to be running throughout COP15.
The UK government will of course be participating in that conference – it’s time for the big talk to be matched by the action…

The killing of nature: Ecosystems and Biodiversity Demise, by Geoff Meaden

Countryside lovers and naturalists alike in this county feel the decline of wildlife as much as anyone. Kentish plover once bred on the coastline between Dungeness and Greatstone, but urban sprawl put paid to this country’s only substantial population of the species (pic David Mairs)

In the Autumn-Winter 2018 edition of Kent Voice we published the first, edited, part of Geoff Meaden’s article on ecosystems and biodiversity demise.
Here, as promised, is the entire, expanded piece in which he not only highlights the pressures on our natural heritage but considers a range of approaches to reversing the trend of environmental loss 

Surely no one reading this will be unaware that, at any scale from local to international, and in any place from the tropics to the subarctic, most natural ecosystems face rapid degradation and that biodiversity losses continue unabated.
Although our TV screens continually relay this demise of nature, still it continues as an apparently unstoppable certainty.
With all this information, plus imploring from conservation organisations, why do humans seem hell-bent on bringing about biological extinction for the planet?
After a look at some relevant factors on a wider scale, I hope here to open a small window on possible causes for the demise and suggest solutions at the local level.
As a 10-year-old in 1952 I remember going to Saturday-morning pictures to see a film called Where No Vultures Fly. It showed Africa in all its natural glory, but even then the unsustainable destruction of wildlife was recognised and the film demonstrated that wildlife parks would soon be necessary if biodiversity was to be maintained.
In the 66 years since the film was released, Africa’s human population has risen from a quarter of a billion to one and a quarter billion – a fivefold increase. And it has changed from having largely undegraded natural environments to a continent that is almost completely human-dominated.
What has happened in Africa has been replicated in Central and South America, as well as in much of Asia, while no continent has been without severe environmental damage.
As a measure of this damage, the weight of all larger land mammals on Earth now comprises 33 per cent Homo sapiens, 66 per cent our pets and livestock (domesticated animals) and just 1 per cent are wild animals (see Table 1).
The latest State of Nature report for the UK (2016) shows that abundance of 2,500 terrestrial and freshwater species has fallen by about 20 per cent over the last 40 years, but for the 213 species with highest conservation priority abundance the decline is close to 65 per cent.
Our planet is now almost completely anthropocentric, with the world’s human population continuing to grow at some 80 million a year. The planet has finite resources, making this growth totally unsustainable; if nothing changes we are on course for massive biological extinctions.

This reversal of Earth from being a ‘nature-bountiful’ planet would seem to imply the problems are not being tackled.
This is far from true.
There is no end of environmental organisations ranging from local to international; from broad-based to specific; from large to small membership; from being talking shops to action- or activity-based; and from public to charity or private organisations.
Some of these organisations have memberships measured in hundreds of thousands and financial accounts that turn over millions of pounds annually. So what is going wrong?
Why are numerous animals on the verge of extinction? Why doesn’t rainforest destruction decrease? Why are coral reefs almost a thing of the past? Why is Britain one of the most nature-depleted countries in the world? Why is no one apparently really listening to what David Attenborough and others are constantly saying?
These questions are far too complex to answer at an international or national scale, so here I examine some causes of biodiversity and ecosystems demise, mainly at a local level, before postulating some ideas for reversing this process.
In Kent we are blessed with a relatively wide range of natural biomes. These include extensive coastal plains, chalk downs, clay vales, river floodplains and areas reclaimed from the sea, each giving rise to a range of vegetative biomes such as marshland, natural grassland, mixed deciduous woodland and heathland.
Into these vegetation zones variations in the physical structure of the land help to create a random assortment of micro-habitats. Moreover, we have had imposed centuries of human development, which has led to a panoply of additional vegetative environments that include hedgerows, copses, planted woodland and coppiced woodland, plus an assortment of farmland types (essentially arable and grazing land).
The potential for biodiversity variation could be great, and indeed it once was. But where and why has much of Kent’s nature gone? It might be useful to address what I see as important points contributing to local, and to some extent national, ecosystems and biodiversity demise:

  1. Pressures from population growth
    This is easily the most important longer-term reason for the demise of nature. In Kent we have seen particularly high population growth over recent decades, the convenience of accessibility to London being a primary factor. The population here is now growing by some 15,000 per annum compared with ‘only’ 8,000 per annum in the late 1990s. Many in the population are well placed to enjoy a comparatively good lifestyle, which almost inevitably has negative impacts on the environment in terms of ‘environmental consumption’, for example through building homes and utilising wilder areas for leisure pursuits.
  2. Habitat loss and fragmentation
    For many centuries the main cause of habitat loss was its conversion to productive farming land. The compatibility of this ‘new land’ with the requirements of nature has declined with the degree of applied technology and we now have what is to a large degree a monoculture where ‘nature’ is virtually excluded. Population growth also leads to increased housing demand, plus demand for infrastructure, retail and employment. Although some of this demand is met from brownfield sites, most is not. Natural habitats are inevitably gnawed at and increasingly the size and connectivity of individual units of wild space is eroded. Kent is particularly hard hit because the density of human constructs is already high, so the obstacles to achieving larger and more integrated biological units are almost insurmountable.
  3. Pollution
    Most of us are aware of the vast range of insecticides, herbicides, fertilisers and assorted chemicals deposited on our rural environment (plus back gardens). These chemicals are mainly aimed at increasing food production for humans and little attention is given to the negative consequences for biodiversity. A walk through any Kentish orchard in spring reveals almost a complete lack of pollinators, doubtless caused by too many chemicals. Of probably greater overall concern is the leaching of pollutants into waterways, where they are concentrated into relatively narrow channels and often added to by discharges from sewage plants. In Kent this is a particular problem because rainfall is low and sub-face geology encourages water infiltration; thus there are frequently low water levels.
  4. A failure to appreciate or react to the problems
    We can make a fair assumption that, despite the variety of environmental information constantly streamed from a range of media, too many of us give insufficient thought to what is happening to the natural world. Even if we do think about this, how many of us take the trouble to take part in nature-conserving activities? While it is true that there are many conservation volunteers and practitioners, as a proportion of those that are really needed to ‘make a difference’, the number of practitioners is too few and conservation groups are coping inadequately with the decline of nature. Perhaps the basis of this lies in the Darwinian concept of survival of the fittest: we are each individually programmed for self-preservation and too many of us go through life ‘fighting for ourselves’. So, perhaps rather simplistically, our individual actions are geared mainly towards making life better for ourselves. Too many of us care insufficiently for our surroundings, be they built constructs or nature. Human nature prevaricates against achieving the necessary behavioural change.
  5. Too much public access to ‘nature’
    We must recognise that people want to ‘see and visit nature’. Hence we are invited to visit a wide variety of attractions, and local councils and conservation groups promote new cycle paths or species habitats as places to visit. But in many cases this has gone too far and there are now few places in Kent from where the public are barred on the basis of nature protection. Just as humans need refuges of peace and quiet, I am quite certain that many species require the same. Human disturbance is a major factor behind species decline.
  6. Disease and alien invasions
    The position of Kent in relation to the Eurasian landmass means this county is particularly vulnerable to invasive species. The basic causes of invasions are the four Ts of trade, travel, tourism and transport, plus, more recently, climate change. Of course, species have always migrated by various means and there is some difficulty in identifying what constitutes a native species. Nevertheless, even a cursory examination shows invasion rates are accelerating, with at least 12 species of tree having become vulnerable to extinction from increased disease invasions in the past two decades. In some cases such invasions may cause little harm to ecosystems or biodiversity, either because the invader can easily integrate within a specific ecosystem or because it fails to compete with existing organisms. At the other extreme, invasions can wreak havoc, especially regarding fungal infections or viruses. In Kent we have seen decimation of amphibians through fungal infections; in many areas toads and frogs seem to have disappeared. The acceleration of climate change will surely exacerbate both disease and species invasions.
  7. A concentration on economic growth and development
    You only have to read local-government corporate plans, or witness the power and influence of big business, to realise economic growth and development are the primary goals society seeks. While of course we need jobs as a source of income and satisfaction, the primacy of the economy and its promotion means that social and environmental considerations usually take second place. Ultimately, economic growth and development depend on land and other resources being exploited, which on balance is a negative for nature. There seems little appreciation by many in the business community that the exploitation of nature is eventually unsustainable. I suspect ‘ecosystem services’ are something foreign to the business community.
  8. Lack of centralised cohesive policies
    As mentioned in my introduction, there is any number of groups, bodies, organisations, charities and government departments involved in one way or another with ecosystems or biodiversity research, observation or ‘management’. Although most of these groups are doubtless doing great work, no single organisation has both an overall vision and the means necessary to effectively say ‘Enough!’. With the severity of nature’s decline, why hasn’t central government given impetus to the Department for the Environment to project a necessary ‘office for the promotion of healthy ecosystems’?

I, and many others, fear the real threat of biological extinctions is now so great that it is putting our fundamental life-support systems at risk. A central plan of action must be established so management controls can be identified, rationalised and then implemented.

Even this brief look at some of the factors leading to the accelerating demise of ecosystems and biodiversity reveals society has a huge challenge, and this must be addressed urgently. It is essential we convey the fact that humans are part of an integrated biology living on a tiny planet where the continued existence of life relies on a changing but balanced living environment. And it is this environment that supplies us with the essential ecosystems services without which life is impossible. We must never ignore or forget this.
Saving ecosystems and biodiversity will mean making sacrifices and taking decisions that to date have proved a challenge too far. The challenge is not easy and in Kent it will certainly not be solved by citizens or groups acting alone. There will need to be worldwide efforts, plus the implementation of remedies at European and national levels. A main purpose of this piece is to consider realistically what local people and groups might best do. I now offer some possibilities that could be taken up according to prevailing conditions and personal circumstances.

  1. Giving protection to a wider area
    Several groups and informed experts have emphasised that it is essential some quantified level of strictly protected status is given to a significant proportion of both the terrestrial and marine areas. The recommended proportion varies from expert to expert and is dependent on the scale being examined. Edward Wilson, probably the world’s leading conservation ecologist, suggests that 50 per cent of the land on our planet needs “sacrosanct conservation”, ie this amount of land is set aside solely for nature conservation. At a more local scale, Kent Wildlife Trust has a target that 30 per cent of Kent “is managed to create a healthy place for wildlife to flourish”. Even 30 per cent of Kent is probably a highly ambitious target, but this is likely to be needed if all varied ecosystems are to be maintained and indeed improved. We must take the necessary responsibility to ensure this target is achieved.
  2. Habitat improvement
    If habitats could be improved, there are numerous local sites where greater biodiversity could be encouraged. Examples include degraded ponds, areas of intensive weed infestation, silted stream beds or marshlands, point source pollution along streams and areas where litter or rubbish has accumulated. There is already much activity directed towards improving habitats, but there is almost an unlimited range of work that can still be usefully accomplished. As well as restoring degraded habitats, new habitats can be created that allow for ‘more nature’, for example new lagoons in marshland or along river banks; planting of wildflower meadows, especially along set-aside land; and creating artificial nesting sites in modern barns.
  3. Joining wildlife and local conservation groups
    There are numerous groups whose focus is directed generally towards ‘improving nature’. Membership of such groups gives the opportunity for active or more static participation. For those who are relatively inactive, then just your support and encouragement are welcome, while of course financial contributions are important (if not essential). But groups such as Kent Wildlife Trust, Kentish Stour Countryside Project, RSPB, Friends of the Earth, Bumblebee Conservation Trust, Butterfly Conservation, The Woodland Trust and Amphibian and Reptile Conservation offer a wide variety of mainly voluntary opportunities to ‘get actively involved’. Most of these groups also have action plans explaining their aims and how these aims might best be achieved, while ample information is available on websites.
  4. Nature improvements outside conservation areas
    The majority of land in Kent will always retain a variety of non-conservation purposes, for example housing, industry, transport routes and urban centres. However, most of these areas offer wide opportunities for nature improvement. One obvious example is urban gardens, where nature can be encouraged through bird-feeding, adding flower and plant varieties and perhaps leaving some kind of ‘wild area’. Another important improvement outside conservation areas per se is through the implementation and protection of ‘wildlife corridors’ that often compensate for the fragmentation of ecosystems by allowing wildlife transit routes between dispersed areas of protection. This may be along railway lines and hedgerows, through golf courses and via an assortment of ‘nature stepping stones’. One important set of wildlife corridors that needs considerable enhancement comprises headlands or set-aside land along the edges of countless fields. Too often these areas are literally set aside having had no management or improvements. Most of these non-conservation land areas need to be recognised and given some level of formal protection.
  5. Tackling local wildlife pressure points
    Recognition needs to be given to where existing and planned structures, industries, pollution sources and other major constructs that could be detrimental to ‘nature’ are located or are planned. I suspect we can all think of actual or potential, mainly human, constructs likely to create such pressure points, for example the proposed solar farm at Cleve Hill, the former animal-rendering plant at Thruxted Mill and the sewage plant at Bybrook. We can all play a part in ‘watching’ these developments and, if necessary, contact the owner or the local authority if there are problems. These single points can do environmental damage that may be out of all proportion to the size or scale of the pressure point itself.
  6. Data gathering
    For the great majority of local biodiversity there is a deficiency of quantitative and locational data. Local environmental organisations ought to be challenged as to the data they can provide and whether they think that adequate actions to redress negative situations can be addressed via their existing data. It is well known that the RSPB organised an annual garden bird count and this is an invaluable source of knowledge in respect to wild bird populations, at least in urban areas. But this data collection ideal needs extensive replication across a much wider biome and species range. As long as methods of data collection can be appropriately standardised, the actual data can easily be gathered. Most of the larger wildlife organisations should have the resources to turn the data into useful information (text plus tables, graphs and maps) and eventually time-trend analyses. The use of data gathered can be essential to wildlife-targeted recovery plans – something all major local environmental or conservation groups should aspire to.
  7. The identification of keystone sites or areas
    For all the Kent biome types and for a range of important indicator species, it is vital to select areas where either the biomes or the selected species are thriving. Once selected, these sites need to gain protection so the area is sacrosanct from built development; it may also be necessary to bar general human access to some sites. It is now well known that Marine Protection Areas (MPAs) have an excellent capacity to not only give protection to species within the area but also to act as overspill sources. Thus, when populations build up within an MPA the population pressure obliges animals or plants to move out into surrounding waters and soon replenishment of these waters becomes noticeable. The same general principle is likely to work in terrestrial ecosystems, though strict management may be necessary.
  8. Friendly persuasion
    Since the reversal of ecosystems and biodiversity declines is never likely to be accomplished solely by actions on a local or Kentish scale, it will be vital that both groups and individuals participate in ‘friendly persuasion’ across the widest possible audience:
    l ‘Friendly’ because if something needs to be done, success is more likely to be achieved through a positive and friendly approach
    l ‘Persuasion’ because we are attempting either to change someone’s mind or to show that our suggested approach needs to be activated.
    There is a myriad range of measures that might come under this category, such as letter-writing to decision-makers or to the press, issuing press releases, spreading the word via social media, circulating petitions, talking to a councillor or your MP and giving public talks.
    These measures must be pursued with vigour, determination and commitment – as if our lives depended on what we are doing, which very surely they soon will.
    It is important to note that before embarking on any campaign it is essential to be well informed on the particular aspect of a topic about which you feel most strongly. This is important because we do need to change mindsets; if people were as convinced as we must be, then the chances are that the status of ecosystems and biodiversity would not be in their present dire situation.

There is no evidence that any local or international person, body or group has an overall perspective on the management priorities necessary to halt ecosystems and biodiversity decline.
A body like the United Nations should have a whole agency committed to fostering the future of ‘nature’, but the UN Environment Programme’s ‘Convention on Biological Diversity’ has no such comprehensive plans, for example like those of the Intergovernmental Panel on Climate Change for combatting worldwide climate change.

Likewise, the Department of the Environment should be the lead organisation in the UK, and indeed this year Michael Gove, Secretary of State for Environment, Food and Rural Affairs of the United Kingdom, produced a 25-year plan for the environment, but although this plan recognised some of the main “actions that are needed”, it said almost nothing on “how the plans would be implemented”. The same can said of earlier government plans.
Vision, action and coordination will be vital to achieve the following essential management actions:

  • The appointment of an ecosystems and biodiversity champion
  • Financial commitments, primary aims and objectives
  • An overall management structure
  • Developing suitable metrics for measuring progress
  • Data gathering and processing
  • Establishing priority actions
  • Delegation of specific roles to existing nature conservation groups (a rationalisation of effort)
  • Building a volunteer structure.

Most of these actions could best operate at county level. An oversight body in Kent might be Kent Wildlife Trust, Kent Nature Partnership, Environment Agency or Natural England.
It would be of interest to find out what actions any of these groups are taking to ensure that the overall demise of nature does not continue.

Our wonderful nature is in serious trouble and it needs our help as never before”, David Attenborough, State of Nature 2016

I also believe that an organisation going under the title Campaign to Protect Rural England needs to be at the forefront of attempts to reverse the diminishing fortunes of our local ecosystems and biodiversity.
